NETWORKS

It is possible to connect a number of computers and other electronic devices to create a computer network. The computers and devices which are part of the network can “talk” to each other and exchange information. In addition to the computers and devices which are connected to other devices are often needed for the network to work correctly. Examples for such devices include hubs and switches. Different kinds of network can be connected to each other with a router. Firewalls are commonly used to protect the network. In general, networks that use cables to connect can operate at higher speeds than those using wireless technology.

A Local Area Network (LAN) connects computers which are close together. Building a LAN is easier than connecting different networks by a Wide Area Network (WAN). The largest Wide Area Network is the Internet. Computers can be part of several different networks. Networks can also be part of bigger networks. The local area network in a regional office or store is usually connected to the main corporate network. These connections may allow access to the Internet, for example to show computers in a store, display its catalogue through a web server, or convert received orders into shipping instructions.

A network must be connected with appropriate hardware. This can be wired or wireless. For a simple LAN, computers, media and peripherals are sufficient. WANs and some large LANs need some additional devices like a bridge, gateway or router to connect different small or large networks. A network needs a communication protocol. Microsoft Windows, Linux and other operating systems use TCP/IP. Apple Macintosh computers used Appletalk in the 20th century, but also use TCP/IP now.
