Type - type of Computer Networks

The computer network is a set of multiple computers and other devices that are connected to each other using certain rules. Based on the scope of its reach, the computer network can be divided into several types. Types of Computer Network is a LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network), Intranet and Internet. Here is a description of the Types of Computer Networks:
A. Local Area Network (LAN)
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 based on IEEE 802.3 Ethernet technology using the switch, which has a data transfer rate 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 itself, in contrast to the concept of terminal dump. Each computer can access resources on the LAN in accordance with the permissions that have been set. Resources can be data or a device like a printer. 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. Has a higher data rapidly2. Covers a narrower geographical region3. 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
2. Metropolitant Area Network (MAN)
Metropolitan area network, or abbreviated to MAN is a network in a city with high-speed data transfer, linking the various locations such as campuses, offices, government, and so forth. MAN network is a combination of several LAN. These range from MAN between 10 and 50 km, MAN is a network the right to build a network between the offices in the city of factories / establishments and headquarters within its range.
3. Wide Area Network (WAN)
WAN stands for information technology terms in English: Wide Area Network is a computer network covering a large area as an example of the computer network between regions, cities or even countries, or can be defined as well as computer networks require routers and public communications 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 computer that is intended or can be accessed only by one party. For example: Telkom Telkom Pekanbaru and Jakarta.
5. Internet
Internet (interconnected-networking) is a computer network that covers the entire area of ​​the world (global) so everyone in this hemisphere can communicate and exchange data on the Internet.
