Types of Computer Networks: LAN, MAN, WAN, VPN
There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world. What is LAN?
Wide Area Network Advantages and Disadvantages
A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A computer network can be categorized by their size. A computer network is mainly of four types :. It is a low range network. Extranet: An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol. It is used for information sharing.

It is generally limited to a geographic area such as a writing lab, school, or building. Computers connected to a network are broadly categorized as servers or workstations.
Cisco Network Templates. Public libraries and government agencies typically use a MAN. Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. This will reduce cost of hardware purchases. Me aca5 at work. By running a large network connectedness, information can be disseminated more widely, rapidly and significantly.
A metropolitan area network MAN is a network which covers a city or a large university campus. MAN usually involves connection of fiber optics wires to boost data transfer speed. MAN depends upon different technologies to establish a network. Some of these technologies are mentioned below Its range is within kms. ATM Asynchronous transfer mode was developed in to transfer digital data fast. In ATM data is distributed online in the form of small fixed size packets.
