Introduction to Networking
A network is a group of computers, printers, and other devices that are
connected together with cables. Information travels over the cables, allowing
network users to exchange documents & data with each other, print to the same
printers, and generally share any hardware or software that is connected to the
network. Each computer, printer, or other peripheral device that is connected to
the network is called a node. Networks can have tens, thousands, or even
millions of nodes.
Like most things, networks are are assembled according to certain rules.
Cabling, for example, has to be a certain length, each cabling strand can only
support a certain amount of network traffic, etc. The rules that govern how a
network is set up is called its topology. The most popular topology in use today
is called Ethernet, which consists of computers and peripherals cabled together
in specific ways. Ethernet is relatively inexpensive, easy to set up and use,
and very, very fast.
Ethernet networks are categorized by how fast they can move information. Speed
is expressed in megabits per second (or Mbps), where one "bit" is equal to 1/8th
of a character, letter, or number. There are currently two Ethernet speed
categories. Standard Ethernet operates at a fast 10Mbps, which is quick enough
for most networking tasks. Fast Ethernet, by contrast, races along at a
blistering 100Mbps, making it ideal for desktop video, multimedia, and other
speed-hungry applications. The new technology behind Fast Ethernet, which was
introduced in the beginning of 1995, is not readily compatible with standard
Ethernet. Making the two "talk" with each other requires special equipment (see
switching hub below) and some knowledge of internetworking. If you're building
your first network, decide whether to go with standard or Fast Ethernet before
you begin shopping around for network hardware and software. Unless you plan on
using video, multimedia, or heavy graphics software, plan on using standard
Ethernet.
Why would I want to network my PCs?
- Share Internet access, printers, and hard drives
- Communicate with the family
- Download music and video to shared devices in the home
- Play PC games on your local area network
More and more households are using more than one computer. In the United
States, about half of all households have computers, and of these more than 20
million households have more than one computer! (IDC) Home networks are becoming
increasingly common to realize the tremendous opportunities sharing computers
offers! |
