Definition of a LAN (Local Area Network)

 Commonly abbreviated as Local Area Network LAN is a computer network whose network covers only a small area, such as campus computer networks, buildings, offices, in homes, schools or smaller. Today, most LAN technology based on IEEE 802.3 Ethernet switch using the device, which has a data transfer speed 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, the current 802.11b technology (or so-called Wi-Fi) is also often used to form the LAN. Places that provide LAN connectivity with Wi-Fi technology called hotspots.

On a LAN, each node or computer has its own computing power, in contrast to the concept of terminal dump. Each computer can also access resources on the LAN in accordance with the permissions that have been set. These resources can be data or devices such as printers. On a LAN, a user can also communicate with other users by using the appropriate application.


In contrast to Wide Area Networks or Wide Area Network (WAN), the LAN has the following characteristics:

1. Having rapidly higher data
2. Covers a narrower geographical region
3. Does not require telecommunications lines leased from telecom operators


Usually one of the computers on the network computer will be used to manage all servers in the network system
WAN


WAN is short for the term information technology in English: Wide Area Network is a computer network covering a large area as an example of a computer network between regions, cities or even countries, or can be defined as well as computer networks require routers and public communication channels.


WANs are used to connect a local network with other local networks, so users or computers in one location can communicate with users and computers in other locations.

MAN


Metropolitan area network or abbreviated to MAN. A network in a city with high speed data transfer, which connects various locations such as campuses, offices, government, and so on. MAN network is a composite of several LANs. These range from MAN between 10 and 50 km, MAN is a network that tepaMetropolitan area network or abbreviated to MAN.
