1. 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. Currently, most LANs based on IEEE 802.3 Ethernet technologies using a switch 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 a LAN. Places that provide LAN connectivity with Wi-Fi technology called hotspots.
On a LAN, each node or computer has the computing power of its own, different from the concept of a terminal dump. Each computer can also access resources on the LAN in accordance with 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 Network or Wide Area Network (WAN), then the LAN has the following characteristics:
1. Has a higher data rapidly 2. Covers a narrower geographical area 3. Does not require leased telecommunication lines from telecom operators
Usually one of the computers on the network computer will be used to manage all the servers in the network system
2. Metropolitant Area Network (MAN)
Metropolitan area network or MAN is abbreviated with 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. Coverage of this MAN among 10 to 50 km, MAN this is the right network to build a network of offices in one city of factories / agencies and headquarters are located within its reach.
3. Wide Area Network (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.
4. Intranet
Intranet is a network of specialized computers that are only intended or can be accessed by one party.
5. Internet
Internet (interconnected-networking) is a computer network that covers the area around the world (global) so everyone in this hemisphere can communicate and exchange data on the Internet.
