Computer Networks are the basis of communication in IT. They are utilized in a huge variety of ways and can incorporate various types of networks. A computer network is a set of computers that are associated together so they can share data. The simplest examples of computer networks are from the 1960s, yet they have made some amazing progress in the 50 years from that point forward.

Types of Network

There is a wide range of types of networks, which can be utilized for various purposes and by various kinds of individuals and organizations. Here are some of the network types that you might come across:

Local Area Networks (LAN)
A local area network or LAN is a network that associates computers within a limited area. This may be in a school, an office or even a home.

Personal Area Networks (PAN)‍
A personal area network is a network that depends on a person's workspace. The person's device is the focal point of the network, with different devices associated with it. There are also wireless personal area networks.

Home Area Networks (HAN)
‍A home area network interfaces devices inside a home environment. It may incorporate PCs, tablets, cell phones, printers, TVs and different devices.

Wide Area Networks (WAN)
‍A wide area network is a network that covers a bigger area, as a rule with a span of more than a kilometer.

Campus Networks
‍A campus network is a LAN or set of associated LANs which is utilized by a government office, college, company or comparable association and is normally a network across a set of buildings that are near one another.

Metropolitan Area Networks (MAN)
‍Metropolitan area networks are networks that stretch over a region the size of a metropolitan zone. A MAN is a series of associated LANs in a city, which may also interface with a WAN.

Enterprise Private Networks
‍An enterprise private network is utilized by an organization to interface its different sites with the goal that the various locations can share resources.

Internetworks
‍Internetworks connect various networks to build a bigger network. Internetworking is frequently used to describe building a huge, global network.

Backbone Networks (BBN)

They are: Satellite-Based Systems: These systems give communication services to rural networks and isolated territories, for example, islands. Satellite systems are intended for a Gaussian or Rician station with K factor more prominent than 7 dB. These systems can be of two kinds: Technology designed explicitly for WLL applications and Technology piggybacked onto mobile satellite systems as an aide service of these. The previous offer quality and grade of service equivalent to wireline access, yet it might be costly. The last promises to be less costly but due to bandwidth capacity limitations, may not offer the quality and grade of service comparable to plain old telephone utility (POTS). A case of a satellite-based technology explicitly designed for WLL is the HNS telephony earth station (TES) technology. Advantages: • The low bit rate for voice and data. • Low-cost mobile terminals. •
