নেটওয়ার্কের প্রকারভেদ || Network Types, The network can be divided into three main types:
১. A local area network is a network composed of several computers located in the middle of the same building. This is called LAN. Such networks use very simple technology and usually do not require internetworking devices.
2. An Internet network consisting of several LANs within the same city is called the Metropolitan Area Network. This is briefly called Man (MAN). This type of network requires an internetworking device.
৩. Wide area network is built on remote LANs. This is abbreviated as WAN. Such networks are quite complex and usually span a large geographical area.
LAN, MAN and WAN are different from each other. Apart from their geographical location, there are differences between different technologies used.
Devices used in the LAN are usually very accessible and low cost. Such a network is usually established in the office court and it is sufficient for one person to take charge of the management. On the other hand, MAN or WAN requires the use of very complex and expensive devices. It is also difficult to make. Such network management requires an experienced network administrator, and it is not possible for one to manage the entire network.
Apart from the networks mentioned herein it is referred to as a campus area network or a network called CAN. It is usually connected to one building to another by means of high-fiber fiber optic connections.
