Network Basics

A network, when talking about computers, is a group of computers that are linked together. This allows people to share resources such as printers. It also cuts down on costs of programs. For example, without a network, a person would have to buy the programs like word processors for each computer. With a network, you can purchase all of the programs once and download them to all computers that are a part of the network.

The Different Types of Networks
There are three different types of networks:LAN, MAN, and WAN. LAN stands for Local Area Network. MAN stands for Metropolitan Area Network. WAN stands for Wide Area Network.

Each of these networks covers a different distance, and as such, is suited for different puroposes.

Network Hardware
Networks are set up using various special devices. These include: NIC (Network Interface Card), hubs, switches, bridges, routers, gateways, and modems.

Trends and Issues
Wi-Fi has become one of the most popular ways to network. Also, the way things are going now, computer chips may be placed in common household items. This may or may not be a bad thing.

Networking isn't all good, however. If your router is messed up, the nodes attached to a network will not be able to communicate with each other. If one of your wires is messed, the network will not be able to work at all. If two network have the same IP Adress, both networks will be shut down.
