The formation of Local Area Network Abstract:

This paper summarizes the Local Area Network，A brief introduction on the LAN to understand its basic structure, characteristics, uses. And presented some information on switch-related technologies, such as its role, functions. Finally, a simple example of the campus network, using knowledge of the campus network to set up.

Part I: LAN Summary

1. LAN concepts:

LAN is dispersed within a limited geographical area (such as a building, a sector) multiple computers connected through the transmission medium of communication networks, through full-featured network software to achieve communication between computers and share resources with each other. LAN is usually in the tens of meters to a few kilometers within a local area network can accommodate several to several thousand computers. Now look at the characteristics according to the LAN, local area network has the following features:

LAN distributed in relatively small geographic range. Because it uses a different transmission capacity of transmission media, so the LAN transmission distance is also different.

LANs are often used for a particular group. For example, a company, a unit of a block of flats, certain schools.

2. LAN essential component

LAN network hardware and network software from the two parts. Network hardware are: servers, workstations, and network transmission medium to connect components. Network software including network operating system, control information transmission network protocol and the corresponding protocol software, a large number of network application software. Figure 2.1 is a relatively common local area network.
