In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.
Networks can be categorized in several different ways. One approach defines the type of network according to the geographic area it spans. Local area networks (LANs), for example, typically span a single home, school, or small office building, whereas wide area networks (WANs), reach across cities, states, or even across the world. The Internet is the world's largest public WAN.
Computer networks also differ in their design. The two basic forms of network design are called client/server and peer-to-peer. Client-server networks feature centralized server computers that store email, Web pages, files and or applications. On a peer-to-peer network, conversely, all computers tend to support the same functions. Client-server networks are much more common in business and peer-to-peer networks much more common in homes.
Here is the networking hardware you need to set up a small network:
Network adapter cards: expansion cards that provide the physical connection between each computer and the network. The card installs into a slot on your computer, just like a sound card or modem card. Some newer computers have a network adapter already built into the system. Laptop computers often use a card that slides into a PC card slot.
Network hub: the central connection point for network cables that connect to computers or other devices on a network. The hub has several network cable jacks or ports that you use to connect network cables to computers. The hub contains circuitry that enables each computer to communicate with any other computer connected to the hub.
Network cables: special, unshielded twisted-pair (UTP) cables used to connect each computer to the hub.
This is just a bit of what you can do with networking...
Stay Connected......
