If you have not decided already,you will soon want to network your two or more computers in your home. You want to be armed to the teach with knowledge of just what it takes to connect your computers to one another.
You first should decide which network is best your you. If your computers are in the same room,the Wireless network should not be considered.The wired by cable network should work just fine.
Computer that may be close to each other but cannot be seen may and have phone jacks close by can easily be networked with the HomePNA Network.While PCs that are far from each other can be connected with the powerline network,assuming wall outlets are nearby.
And when there are computers in different rooms and you want the convenience of moving the systems from room to room,the more expensive Wireless Network is the way to go.After you decide on the type of network that is best for you,knowing what components you’ll need to purchase will be a great help.Let’s take a look at each network and the components needed to get it up and running.
The WIRED ETHERNET NETWORK
If your computers are in the same room,the basic network kit can wire your systems together.Be sure to carefully open any kit or component you purchase and do not damage the box it came in.The purpose for this is to make it easy to return the component if needed.
Basic kits will have instructions and software for the network… Read the rest

Wireless networks use radio waves instead of wires to transmit data between computers. Here’s how:
The Binary Code: 1s and 0s
It’s well known that computers transmit information digitally, using binary code: ones and zeros. This translates well to radio waves, since those 1s and 0s can be represented by different kinds of beeps. These beeps are so fast that they’re outside the hearing range of humans.
Morse Code: Dots And Dashes
It works like Morse code, which is a way to transmit the alphabet over radio waves using dots (short beeps) and dashes (long beeps). Morse code was used manually for years via telegraph to get information from 1 place to another very quickly. More importantly for this example, though, it is a binary system, just as a computer system is.
Wireless networking, then, can be thought of as a Morse code for computers. You plug in a combined radio receiver and transmitter, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from here to there.
Wavelengths And Frequencies
You might wonder how the computer can send and receive data at high speed without becoming garbled nonsense. The key to wireless networking is how it gets around this problem.
First, wireless transmissions are sent at very high frequencies, which allows more data to be sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) — a frequency similar to mobile… Read the rest
