Motorcycle Automatic Transmission – The Top 3

Motorcycle enthusiasts love a wild goose chase such as the famously beloved, Bigfoot. Many motorcyclists fail to believe that there is actual automatic transmission motorcycles that exist. This is not true because the knowledge isn’t out there. This is actually true because of there just aren’t to many readily available. The top three automatic transmission motorcycles really exist and the proof is found by reading on.

3. The Honda DN-01

The Honda DN-01 was introduced in 2005 as a cruiser motorcycle. This is one of the first of very few automatic transmission motorcycles ever released. The bike didn’t actually make it on showroom floors until 2008-2009. This bike is so powerful to the consumer that it is still being offered in shops as of early 2011. Missing you chance to check out the Honda DN-01 is just wrong. The Honda DN-01 is just one of those bikes you can’t miss a chance to try out for yourself.

2. The Aprilia Mana 850

The Aprilia Mana is a newer automatic transmission motorcycle that was just released last year. This bike is fast and very powerful. The Aprilia Mana 850 is a sleek sports bike that offers highlights from leather to chrome and everything in between. There is nothing better than a quick bike with the backing of being an automatic transmission motorcycle. The Aprilia Mana 800 makes its way to this top three list for being a solid bike with an even nicer ride.

1. The Honda CB750

The Honda CB750 has had many models in its series between 1969-2003. The Honda CB750 automatic transmission models is better known as the Honda CB750 Hondamatic. This model is one of a kind that has a coil ignition start and a solid inline four stroke SOHC air cooled engine. The only downfall to this model was the fact that the gear changing was not automatic. Instead, each gear was chosen by a foot-controlled hydraulic valve. This bike only sold in the North American market but can now be found all over the world.

What is CNC?

CNC is the acronym of Computer Numeric Control and it is often associated with plasma cutting as in CNC plasma cutting. A plasma cutting unit that is controlled by CNC is controlled by a computer. There are two basic classes of controls, industrial PC-based control systems and hobbyist/artisan PC-based control systems. The industrial CNC systems, such as the ones produced by Hypertherm or Burny, are robust enough to stand up the harsh production environments. They have a touch screen that can be housed inside of a heat shield for additional protection. The industrial CNCs are very costly, but they come highly recommended for any application because they are not vulnerable to typical PC problems meaning they have very little down time. Due to the high cost you will not often find industrial scale CNCs in a hobbyist’s garage. The artisan and the hobbyist plasma cutter use standard PC-based controls with I/O cards for controlling the plasma systems and the drives. Since these are regular PCs they are prone to an array of computer problems, but none that cannot be fixed.

If you want to use a CNC for your plasma cutting there are some things you will need. You will need a table for the cutting to take place on. On each side of the table you must have a rail that the drives can use to move the plasma systems; we will call this the x-axis. A bridge or gantry must span the table and each end must rest on the rails. The plasma system must be attached to a rail on the bridge which will allow it to move back and forth; the y-axis. Industrial strength set ups us fabricated steel for the construction of the table, rails and bridge. On the other hand, extruded aluminum is used for the hobbyist and artisan CNC plasma cutter set ups. The difference is that the steel is more robust and will withstand constant use whereas the aluminum can only withstand occasional use. If building one of these machines sounds a little scary to you, there are lots of kits that you can buy or you have the option of buying ready built CNC plasma cutters.

If you cruise the web you will be able to find many videos showing CNC plasma cutters in action. It is not the easiest topic in the world to explain and I suggest you check out some videos if you have not seen a CNC plasma cutter before.

Everything You Ever Wanted To Know About Condoms

If there was ever an invention to make sex as safe as possible, it has to be the condom. Not only do they prevent the spread of sexually transmitted diseases, but they’re very effective at preventing pregnancy too. No other form of contraception is so reliable and versatile. So what’s not to love?

Buying them

So you’re shy about asking for them? Supermarkets and gas stations carry condoms these days – you can buy them from a machine in the washroom. Sex clinics give them out by the handful for nothing. And if you still feel weird about getting your hands on condoms – just consider how it would feel buying medicine to treat an STD instead.

Carrying them

Is it presuming too much to take condoms on a date? Frankly, that attitude hasn’t been seen since the fifties. So the girl might realise you do have sex and you wanted it with her. Is that an insult? In any case, you don’t have to take them out your pocket and wave them around. If you get to the point where you need one, you’ll both be happy to see that little foil wrapper, never mind who was carrying it!

Using them

Remember the classes where you practised with a banana? Do yourself a favor, practise with the real thing. Use a whole pack if you need to – keep trying till you know how to get one on properly. You won’t be able to put on a condom if your penis isn’t fully erect – but remember that the penis releases fluid that can spread STIs or contain sperm even before it’s erect. Remember to pinch the ‘teat’ at the end before you unroll the condom down your penis – you might want to leave a bit more space at the top to prevent the condom from splitting. Keep this teat pinched between your fingers as you unroll the condom, and make sure it’s fully covering your penis before and during sex. Don’t feel shy about interrupting your lovemaking to put one on – that pause can only build the excitement!

Last words

Oil based lubes, sharp fingernails, jewellery and out of date condoms are all recipes for disaster. Use a special lubricant. Some people find they have an allergy to latex – condoms now come in allergy-friendly latex-free varieties. In fact, there are now a vast number of different shapes, colors, sizes and flavors of condom. Experiment to see which ones you and your lover prefer – perhaps a ribbed variety for more stimulation or a condom with extra lube for very sensual sex. You should use a condom or dental dam for oral sex too, and change condoms for every new orifice or sex act.

Finally, to get rid of a condom, wrap it and bin it. Never flush a condom down the toilet.

Deadly Staph – Tips for the Prevention of Staph Infections

Over the past few years some dangerous Staph bacteria have become resistant to antibiotics. Only recently has the news media focused on this serious new health problem, which is of urgent concern to our schools. These killer bacteria, called methicillin resistant Staphylococcus aureus or “MRSA”, have recently caused panic in schools in the USA. Some infected students have become seriously ill and some have died after these antibiotic resistant bacteria invaded their blood stream. Most Staph bacteria only causes minor skin infections and are treated with antibiotics. Serious and deadly infections however, develop when antibiotic resistant bacteria (MRSA) is involved. The best methods for prevention of all types of Staph infections involve general cleaning strategies which can be incorporated into the routine cleaning practices at all schools. Here are some tips for limiting the possibility of Staph bacteria infecting your students:

1.) Establish a daily and routine environmental cleaning schedule for your school restrooms and dining areas. The cleaning staff should be trained and monitored to be sure they understand and practice thorough and effective cleaning procedures. Your local health department can provide advice on procedures.

2.) Use germicidal products or a solution of 1 part chlorine bleach and 9 part water to clean any surface that is subject to frequent touching by students, including light switches, doorknobs, faucet handles, hand rails and all restroom fixtures. Use soap and water at a minimum, preferably an all-purpose cleaner, for a daily cleaning of all other floors and surfaces.

3.) Install automatic soap dispensers, automatic hand dryers and automatic paper towel dispensers. These touch-free automatic dispensers will reduce student’s exposure to appliances that are frequently the source of hand transmitted bacteria. like Staph. If your school still utilizes the old manual hands-on dispensers it will be nearly impossible to clean them frequently enough to eliminate the spread of bacteria.

4.) Immediately clean up any surface that has a visible body fluid contamination such as blood, urine or other body fluid.

5.) Make sure automatic soap dispensers and automatic paper towel dispensers are filled with product at all times. This should be part of the cleaning personnel daily routine. Refill the dispensers daily.

6.) Encourage good hygiene. Students should be cautioned against sharing water bottles and personal items, encourages to shower after gym classes and other physical activities.

7.) Require that students cover cuts, abrasions and lesions with a proper dressing (bandage) until healed. Athletics staff should monitor this closely among their athletes.

8.) Clean all items used in athletic activities with an all-purpose cleaner and wash uniforms after each use.

9.) Publish, articulate and post reminders to staff and employees the importance of frequent hand washing with soap and water or the use of germicidal hand gels. Your schools restrooms and cafeteria should have warning signs posted in highly visible areas reminding everyone that hand washing is a requirement of your facility and is everyone’s responsibility.

Following these simple cleaning routines will greatly reduce you schools risk of bacterial infections of all types, including Staph and viruses, such as the flu, and the common cold.

Beauty is Everywhere

As I look out into the world, I see so much to be grateful for. Surrounded by beauty, I am left in no doubt that we live in a spirit filled world that is becoming more authentic in the beauty that it is able to appreciate. For so long we have come to define beauty on a superficial level, but as we grow, so will our ability to appreciate beauty grow within us.

With this, understand that only can we recognize and appreciate what is truly beautiful when we have unified with the essence of our own beauty within ourselves. So many struggle to find the beauty in the world when they look outside. Fearful of what they will encounter, they see a world filled with anger, hostility and ugliness, and because this is what they see, this is what becomes real for them, and they continue to live as their self fulfilling prophecy would have it be.

Neglecting their own beauty, they have swallowed a nightmare pill which alters dramatically the world in which they see. Turning away from the spirit, they have chosen to embrace the ego, which sees things always in a distorted light. With power and strength to gain for itself, the ego is devoted not to searching for beauty, but to finding that which can build it up in the eyes of the world. Concerned with the physical world and pleasing those within it, it is not at all interested in the wisdom of the spirit.

Not wanting to be the protagonist in its own demise, the ego has a vested interest in keeping the true source of beauty from your eyes. Not wanting you to experience the awe that beauty inspires, it seeks to keep you in a state of boredom where you ask no questions of life. Asking no questions, you cease to interact with life, and you deprive yourself of the answers that God wants to give to you. This is what it means to be reactive to life, and to suffer in the process.

Called to be proactive, we do not grow in our experience of life, if we have closed ourselves off to what it seeks to teach us. Wanting to show us the beauty in the world and in ourselves, it is a willing teacher, but a teacher has no role to occupy without a student in attendance. This is why we must be open-minded in beauty’s presence. With much to give, there is much to learn about the beauty of God which manifests itself in all things.

It is said that beauty is in the eye of the beholder. What this means to me is that each of us has the capacity to find beauty in different things. What some label beautiful, others might label ugly, and vice versa. But does it really matter what verdict is passed on whether something is pleasing to the eye or not? What matters absolutely is the seed of beauty to be found in all things that God has created. With the beauty of the creator pervading each of his creations, that beauty is definitely there to see. The question then becomes what is the quality of the vision of the observer?

Many are capable of seeing the beauty in all that surrounds them, but even more are not. Selective in what they ascribe the label ‘beautiful’ to, these people have chosen to honour the mind above the heart, which is all to discriminating. Seeing more than the mind is capable of seeing, the heart knows that it is futile to judge, because it realizes that judgment passed on that which appears in a diminished light is falsely condemned. Seeing only a portion of the whole, much is misunderstood; and embracing only a part, much is rejected as irrelevant. See in this, the dangerous game that we play when we choose to have the ego’s eyes be the filter with which we view the world.

Seeing only fragments of beauty that it has contaminated through its own judgment, much is discarded, and even less honoured, for God cannot be seen by that which despises his presence. Wanting you not to see him, the ego will lead you to label as ugly, much that is beautiful in appearance and substance.

Intense in its loathing, the ego is not always rational in its judgment, and even in its certainty, it misses much to be appreciated. See in this how the ego’s arrogance often leads it to abandon that which could otherwise serve it. Cursed in its blindness, it makes not for wise counsel to the one who searches for a deeper experience of life.

Wanting to experience love, one must consult the heart, being the centre of beauty inside the self. Being not separate from God, it is the gift that God has given us to enjoy the world. Blessed with much, we can find much joy when we look upon the world with spiritual eyes. Hindered not by that which are the ego’s shortcomings, we can see the love behind the barriers, and the distinctions which make the miraculous commonplace.

Blessed in spirit, we must not take for granted that which is capable of teaching us who we truly are. Endowed with wisdom, all of God’s creations are capable teachers, and assuming not a separate identity from him, they are models to be emulated. With this, learn that beauty is distorted as the separation is affected. So as you travel far from him, so will your ability to experience beauty diminish in strength.

Concerned primarily with attaching labels in the moment, what eludes you is the beauty inherent in entering the moment. To enter the moment, is to join with God in your heart, and see what he sees in the physical world. With all that he created being good, you are then able to see the love that pervades everything in the light of the spirit. Appreciating everything just as it is, you understand that it is enough and that the ego does not have to be invited to enhance what is complete in itself.

Complete, the gifts of God are holy in what they hold and what they deliver. Endowed with beauty, they bring to the lost man, much that is invaluable. Longing for God, those who are lost, suffer in their desperation. Convinced of their own ugliness, the memories of their eternal beauty slip into the past. But the past is not lost forever, for every illusion stands to be corrected, and as a partner with eternity, it will not fail to reveal itself in a touch that the moment has in store, for the child who sees clearly now, not yearning for more.

One of the most memorable times that I recall beauty touching me deeply was in Florence when I went to see Michelangelo’s David. I had heard from many people how wonderful this classical piece of sculpture was, but hearing a second hand account doesn’t really prepare you for the effect that it has on the soul, when you see it in person. To say that I was taken aback by its beauty would be an understatement. I was left absolutely speechless! To think that one man saw this masterpiece in that block of marble and saw it as his purpose to bring it to life for all to enjoy is awe inspiring to me.

But as I was standing there, just gazing up at the masterwork, I knew not the distraction of thought that attempted to persuade my mind to intellectualize how the work was brought to life. This allowed me to centre myself and let the profound beauty that emanated from the shiny white surface, move my spirit powerfully in the moment. And as I just allowed the moment to touch me, I felt for a moment just how Michelangelo must have felt with the chisel in his hand and the spirit in his heart, for as I am not alone with my pen, he was not alone with his tools, for with every incision had God’s hand revealed itself so gently and lovingly.

All in all, I spent about an hour in the company of David, listening only to the silence which was my teacher. And as I meditated on what had greeted my senses, I felt a deep sense of appreciation begin to emerge, and as my eyes began to well up with tears, my constant companion placated my fears that I would miss something, a moment, which taught me who I am, not alone in war, but beautiful and fair.

To know Michelangelo must have been to be in the company of a great lover. Here was a man who made it his life’s purpose to serve the world by making manifest in physical form, the love that he carried inside. How else can you explain it? To look into the eyes of David is to know without a shadow of a doubt that he was conceived in love, and because it was this love that filled Michelangelo’s heart, the conception was inevitable.

With this, understand that love never leaves beauty unexpressed, for that is not love’s way. And in the same way that love will never leave beauty unexpressed, so will it never leave the witnesses to that beauty untouched, for the heart that was inspired to bring the beauty to life, is in no way separate from the heart of the witness who has seen in that beauty a clear image of themself revealed.

See in this, how all embodiments of beauty carry a reflection that is not one dimensional. If you were to observe a rose, you would be moved by the beauty of that rose, but what has moved you is not limited to the petals, stem and thorns which make up that rose. What you receive from that rose is an experience of the beauty of nature which is in no way separate from all that the rose is, because nature is the essence of its being. And as it is with the rose, so it is with you, because nature is the very essence of who you are. As God has breathed life into the rose, so has God breathed life into you, and in it you get a glimpse of not only its glory, but your glory as well, which is a stranger not to the glory of God.

Endowed with all that is beautiful, do not doubt what is yours to give, and as you awake from your slumber, so will your brothers and sisters enjoy a more peaceful rest. Not tormented by their hideous nightmares, a new joy will emerge in the form of a dream that is not isolated in how it comes to bless them. As beauty multiplies, so does its visions, in the mind that has unified itself with the heart.

Filled with this love, joy replaces sorrow and gratitude replaces judgment, for as the Lord has spoken, you need not open your mouth to speak. Speaking in glorious tongues, you are left in no doubt that what he has to say is real. Beautiful in its composition, it is undeniably powerful in its resonance. Teaching your heart, the mind finds rest, subsumed by the grace that has cradled it, and when it awakes, immense beauty awaits it, in both its relationship to the physical and the infinite which know no divide. Being what beauty has conquered, love has done its work, through the eye of the spirit that cannot be blinded to the world’s worth.

Cold Sores and Staff Infection

Cold sores are a result of infection with the herpes simplex 1 virus. This is a viral infection that once you have contracted stays in your system for life. The only treatments available are antiviral management, because there is no cure.

A person who suffers from atopic dermatitis should be extremely cautious around anyone with a cold sore. Atopic dermatitis, better known as eczema, is rashes and irritations on the skin caused by any number of environmental allergies. This condition causes very itchy dry patches of skin that can break open and are prone to secondary infection from scratching. Studies have shown that patients with eczema are more likely to carry stash on their skin than those who do not.

The herpes simplex virus can spread rapidly in a person with atomic dermatitis. This can cause an infection known as eczema herpetic. It can spread over the whole body or remain localized in areas of active eczema outbreak. This situation should be monitored very carefully by a medical professional.

Herpes virus is very contagious and the spreading capability increases in the person who has eczema. The virus can spread over the whole body very quickly leaving you open to secondary infections and especially staph. As noted above the eczema carrier is also more apt to have the staph already present on their skin, thus when scratching sores or rashes, the staph can penetrate and make a bad situation even worse.

If you have eczema and been exposed to the herpes simplex virus, it is important that you see your doctor immediately. They may want to start you on an antiviral medication sooner rather than later to ward off a potential outbreak.

Signs that you may be getting a herpiticum outbreak will include blisters, sores within the areas of eczema. These tiny blisters will soon pop and spread the virus at an alarming rate. There is a chance of fatality if not treated properly. You may feel tired or feverish and notice some swelling in the area of the rash.

It is important to note even if you are not overly concerned for yourself, you should be concerned for your family and coworkers. The virus is very contagious and should be treated immediately. Besides early treatment can lessen the severity and duration of your outbreak.

In very severe cases, your doctor may prescribe a bleach bath to kill the bacteria. However, this should never be undertaken without a doctor’s advice as the wrong dilution can cause severe problems. Phototherapy and laser therapy are also alternative therapies that your doctor or dermatologist may consider.

The main thing to remember is prevention is better than cure, use good hand washing practices and keep yourself healthy. When you are run down your immune system becomes compromised and less able to fight off infection and the herpes particles.

Wide Area Network (WAN)

Types and Characteristics of WANs

What is a WAN?

There are two prevailing definitions of a Wide Area Network (WAN). The book definition of a WAN is a network that spans large geographical locations, usually to interconnect multiple Local Area Networks (LANs). The practical definition of a WAN is a network that traverses a public network or commercial carrier, using one of several WAN technologies

What are its Main Components?

The main components for a WAN are routers, switches and modems. These components are described below in the hardware section.

CPE – Devices on the subscriber premises are called customer premises equipment (CPE).

The subscriber owns the CPE or leases the CPE from the service provider. A copper or fiber cable connects the CPE to the service provider’s nearest exchange or central office. This cabling is often called the local loop, or “last-mile”.

DTE/DCE – Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud.

Hardware

In a WAN you will need various types of hardware components for it to function. The typical items of hardware that you will need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a wide area network (WAN) and handles the task of routing messages between the two networks. Operates at layer 3, and makes decisions using IP addresses.

Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. Operates at layer 2, and uses MAC addresses to send data to correct destination.

Modem – Short for modulator/demodulator, a modem enables a computer to communicate with other computers over telephone lines. Operates at layer 1, where signals are converted from digital to analogue and vice versa for transmission and receiving.

Wan Standards

WANs operate within the OSI model using layer 1 and layer 2 levels. The data link layer and the physical layer. The physical layer protocols describe how to provide electrical, mechanical and functional connections to the services provided by the ISP. The data link layer defines how data is encapsulated for transmission to remote sites.

Encapsulation

Encapsulation is the wrapping of data in a particular protocol header. Remember that WANs operate at the physical layer and the data link layer of the osi model and that higher layer protocols such as IP are encapsulated when sent across the WAN link. Serial interfaces support a wide range of WAN encapsulation types, which must be manually specified. These types include SDLC, PPP, Frame delay etc. Regardless of WAN encapsulation used it must be identical on both sides of the point to point link.

Packet and Circuit Switching

Circuit switching and packet switching are both used in high-capacity networks.

The majority of switched networks today get data across the network

through packet switching.

Circuit-switching is more reliable than packet-switching. Circuit switching is old and expensive, packet switching is more modern.

General Routing Issues

What is a Routing Protocol?

A routing protocol is a protocol that specifies how routers communicate and exchange information on a network. Each router has prior knowledge of its immediate neighbours and knows the structure of the network topology. The routers know this because the routing protocol shares this information.

Protocol

RIP (Routing Information Protocol) was one of the most commonly uses protocols on internal networks. Routers use RIP to dynamically adapt changes to the network connections and communicate information about which networks routers can reach and the distance between them. RIP is sometimes said to stand for Rest in Pieces in reference to the reputation that RIP has for breaking unexpectedly and rendering a network unable to function.

Routing Algorithms

Distance Vector

This type of routing protocol requires that each router simply inform its neighbours of its routing table. The distance vector protocol is also known as the bellman-ford algorithm.

Link State

This type of routing protocol requires that each router maintain a partial map of the network. The link state algorithm is also know as Dijkstra’s algorithm.

IGRP

IGRP is a type of distance vector routing protocol invented by cisco used to exchange routing data in a autonomous system. Distance vector protocols measure distances and compare routes. Routers that use distance vector must send all or a portion of their routing table in a routing update message at regular intervals to each neighbour router.

Addressing and Routing

What does routing mean?

Routing is the process of deciding how to move packets from one network to another.

The directions also known as routes can be learned by a router using a routing protocol then the information is passed from router to router along the route of the destination.

IP Address’s

Every machine connected to the internet is assigned an IP address. An example of an IP address would be 192.168.0.1. IP addresses are displayed in decimal format to make it easier for humans to understand but computers communicate in binary form. The four numbers that separate an IP address are called Octets. Each position consists of eight bits. When added to together you get 32 bit address. The purpose of each octet in an IP address is to create classes of IP addresses that can be assigned within a network. There are three main classes that we deal with Class A, B and C. The octets of an IP address are split into two parts Network and Host. In a class A address the first octet is the network portion, this determines which network the computer belongs to, the last octets of the address are the hosts that belong to the network.

Sub netting

Sub netting allows you to create multiple networks within a class A, B or C address. The subnet address is the address used by your LAN. In a Class C network address you would have a subnet mask of 255.255.255.0. A subnet mask identifies which portion is network and which is host. For example 192.168.6.15 the first octet three octets are the Network address and the last octet being the host(Workstation). It is important to subnet a network because gateways need to forward packets to other LANS. By giving each NIC on the gateway an IP address and a Subnet mask it allows the gateways to route packets from LAN to LAN. Once the packet arrives at its destination, the gateway then uses the bits of the subnet portion of the IP address to decide which LAN to send the packets.

Circuit Switched Leased Lines

A circuit switched network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. Here are some terminologies associated with a Circuit switched network.

Frame relay is a telecommunication service designed for cost-efficient data transmission between local area networks (LANs)

Basic rate interference is a service used by small business for internet connectivity. An ISDN BRI provides two 64 Kbps digital channels to the user.

Primary rate interface (PRI) is a telecommunications standard for carrying voice and data transmissions between two locations

All data and voice channels are ISDN and operate at 64kbit/s

Packet Switching

http://www.raduniversity.com/networks/2004/PacketSwitching/main.htm – _Toc80455261

Packet switching refers to protocols in which messages are broken up into small packets before they are sent. Each packet is then transmitted over the Internet. At the destination the packets are reassembled into the original message. Packet switching main difference from Circuit Switching is that that the communication lines are not dedicated to passing messages from the source to the destination. In Packet Switching, different messages can use the same network resources within the same time period.

http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and protocolwhich encodes data into small fixed-sized cells.

ISDN is used to carry voice, data, video and images across a telephone network. ISDN stands for integrated services Digital Network. Isdn also provides users with a 128kbps bandwidth. This is done through frame relay. Frame relay complements and provides a service between ISDN, which offers bandwidth at 128 Kbps and Asynchronous Transfer Mode which operates in somewhat similar fashion to frame relay but at speeds from 155.520 Mbps or 622.080 Mbps. Frame relay is based on the older X.25 packet switching technology and is used to transmit analogue signals such as telephone conversations.

PSDN stands for packet switched data network and is a data communication network. Packet switched networks do not establish a physical communication signal like the public telephone does (circuit switched network) Packets are sent on a fixed length basis and assigned with a source and a destination address. The packets then rely on the routers to read the address and route the packets through the network.

Mobile and Broadband Services

Digital Subscriber line(DSL) is mainly used to bring high bandwidth connections to homes and small business’s over a copper wire telephone line. This is can only be achieved if you stay within the range of the telephone exchange. DSL offers download rates of up to 6mbps allowing continuous transmission of video, audio and 3D effects. DSL is set to replace ISDN and compete with the cable modem in providing multimedia to homes. DSL works by connecting your telephone line to the telephone office over copper wires that are twisted together.

Asymmetric Digital Subscribers Line is most commonly used for home users. It provides a high download speed but a lower upload speed. Using ADSL, up to 6.1 megabits per second of data can be sent downstream and up to 640 Kbps upstream.

http://en.wikipedia.org/wiki/Symmetric_Digital_Subscriber_Line

Symmetric Digital Subscriber Line is a digital subcriber line which runs over one pair of copper wires. The main difference between ADSL and SDSL is the difference in upload and download speeds. SDSL allows the same upstream data rate and downstream data rate as ADSL upstream can be very slow.

[http://searchnetworking.techtarget.com/sDefinition/0],,sid7_gci558545,00.html

HDSL High bit-rate Digital Subscriber Line, one of the earliest forms of DSL, is used for wideband digital transmission within a corporate site and between the telephone company and a customer. The main characteristic of HDSL is that provides equal bandwidth in both directions.

IDSL is a system in which data is transmitted at 128 Kbps on a regular copper telephone line from a user to a destination using digital transmission.

The Local Loop enables operators to connect directly to the consumer via copper local loops and then add their own equipment to offer broadband and other services. This process involves operators accessing local exchange buildings to connect to a network of copper lines which connect them to homes and businesses. BT is an Example of a Local Exchange. The local loop connecting the telephone exchange to most subscribers is capable of carrying frequencies well beyond the 3.4 kHz upper limit.

Benefits of using DSL

DSL can provide virtually instantaneous transmission of voice, data and video over ordinary copper phone lines. A DSL connection can eliminate delays when waiting to download information and graphics from the Internet. It provides users with a cost effective high speed Internet connection. Another benefit is that a DSL connection is always on-line (like a LAN connection) with no waiting time for dialling or connecting.

There are now more than 10 million broadband connections in the UK. By December 2005 there were 9.792 million broadband connections in the UK and the average broadband take up rate during the three months to December was more than 70,000 per week.

“But” vs “And”

Two three–letter words: “but” and “and.” In grammatical terms, they are called conjunctions. They bridge two clauses of a single sentence together. In communication (and negotiation), these words are subtle manipulators of exclusion or inclusion. Generally speaking, “but” excludes, denies, discounts or in some way rejects the previous clause. For example, the statement “she is a very productive employee but she can be a bit demanding” is subtly different than “she is a very productive employee and she can be a bit demanding.” In the first example, the “but” tends to convey a negation of the first clause of the sentence in favor of the second clause of the sentence. In the next example, the “and” tends to convey an inclusion of the first clause along with the second clause.

Take another example: “Yes I understand you need to meet with me before tomorrow’s meeting but my schedule is packed full” vs. “I Yes I understand you need to meet with me before tomorrow’s meeting and my schedule is packed full.” In this example, by using “and” instead of “but” the speaker not only avoids negating the initial clause but also conveys to the listener that his/her concerns about needing to meet are acknowledged.

Using “and” is also a much softer way to say no. For example, the typical “yes, but” can easily be replaced with “yes, and.” For example, the request “We need to purchase new computers” can be responded to with “yes I know, but we can’t until next year” or “yes I know, and we can’t until next year.” The “and” does not negate the “yes” whereas the “but” does tend to convey a sense of canceling out that which preceded the “but.”

The use of “but” is extraordinarily common. In fact, few people actually recognize the subtle influence of using but. If you were to consciously attempt to change “but” to “and” in your speaking, you will notice how odd it feels. But, it is a worthwhile exercise if for no other reason than to become more comfortable with the ability to switch from one to the other. However, there can be a more important reason: using “and” instead of “but” can positively influence dialogue. When using “and” instead of “but” there is a sense of inclusion and acceptance even if the conclusion is a denial or refusal.

Try it out over the next several days. Listen to others’ sentences and when you hear “but” change it in your own mind to “and.” Then, start listening to your own sentences. When you hear yourself about to say “but” change it to “and” but remember one thing…oops…and remember one thing…

What is Bluetooth?

Bluetooth technology specifies a two-way, short-range radio link that enables communication between PCs, mobile phones, PDAs, and other computing, electronic, and home theatre equipment. With Bluetooth, you can easily synchronize contact or calendar data between a PDA and laptop, talk on a hands-free phone, or print without cables. It is a cable replacement technology like infrared, but offers many advantages over infrared.

The Bluetooth specification focuses on keeping costs low, power consumption minimal, and the size small. Its low power consumption means it can be used in battery-powered devices. Bluetooth offers faster data rates and greater   transmission  distances compared with infrared and there are no line-of-site restrictions. It operates at the 2.4 GHz radio frequency, ensuring worldwide operability.

History

Bluetooth is named after a 10th century Danish king, Harald Blatand (Harld Bluetooth) who was known for uniting warring groups in current-day Norway, Sweden, and Denmark. It was originally developed by Ericsson, but is now managed by the Bluetooth Special Interest Group (SIG).

The Bluetooth SIG is an industry group with members from the telecommunications, computing, and chip manufacturing industries. To date over 2000 companies are members. The Bluetooth SIG oversees a qualification program to ensure compliance with the standard and interoperability with other Bluetooth devices. Any device bearing the Bluetooth logo has successfully completed interoperability testing.

Technical Details

Speed: The gross data rate supported by Bluetooth is 1 Mbps. Actual data rates are 432 kbps for full-duplex and 721 kbps for asymmetric  transmission .

Frequency: Bluetooth uses the unlicensed ISM (Industrial, Scientific, and Medical) band at 2.4 GHz. In most countries, this band is available. In a few countries it is reserved for military use, but even these countries are moving to make the band available for general use. Because Bluetooth shares the same frequency range as 802.11b WLAN products, these two technologies cannot operate in the same space under some conditions.

Security: Bluetooth is designed to be as secure as wire using authentication and 128-bit encryption. Applications can also build their own security on top of the Bluetooth connection.

 Transmission  distance: Bluetooth’s typical range is up to 10m. The range depends on the radio power class used. A class 2 radio has a typical range of 10m. More powerful classes support longer ranges and have higher output powers. Most devices use a class 2 radio and mobile devices, like mobile phones, where low power consumption is crucial, can only use a class 2 radio.

Architecture: With Bluetooth, up to 8 devices can be connected simultaneously. A piconet is the term for a collection of Bluetooth devices connected in an ad hoc fashion. All devices are peer units, but one device acts as a master and the other slaves for the duration of the piconet connection. Each piconet can support up to 3 full-duplex voice devices. Within a 10m area, there can be up to 10 piconets.

Applications

Bluetooth is becoming the preferred wireless technology in the WPAN (Wireless Personal Area Network). Personal applications include:

– Users can connect PCs to transfer files.

– Workers can collaborate on the same document using Microsoft NetMeeting.

– Users can connect to a printer without cables.

– Users can synchronize data between a handheld PDA and laptop.

– Users can listen to music via a wireless headset.

– Users can talk on their mobile phone with a wireless headset.

– Users can connect their laptops to the internet using their mobile phone’s GPRS or UMTS network.
