Types Of Computer Networks

While are likewise in their primary objectives, varying types of computer networks achieve different purposes. Networks presently are listed in the following 4 categories.

Local-Area Network (LAN)

A LAN is a collection of linked devices in one tangible location, like a home or an office. LAN’s can be small or large, spanning from a home network with only a family of users to a larger enterprise network with 1,000’s of users and devices. A LAN can include devices both wired and wire-less. Disregarding size, a LAN’s specific attribute is that it links devices that are in a singular, limited area.

Wide-Area Network (WAN)

A WAN encompasses a large geographic area and links together singular users or multiple LAN’s. The Internet can be thought of as a WAN. Large organizations utilize WANs to connect their different sites, remote-employees, their suppliers, and data-centers so they are able to run applications and access required data. Physical connections in WANs may be accomplished by leased lines, cellular connectivity, satellite linking, and other means.

Enterprise Network

A network constructed for a larger organization, usually known as an enterprise, is required to fulfill demanding requirements. Because networking is vital for any present enterprise to function, enterprise networks are required to be highly accessible, scalable, and powerful. These networks utilize tools that allows network engineers and managers to devise, deploy, de-bug, and rectify them. An enterprise is able to use both LANs and WANs across their campuses, subsidiaries, and data-centers.

Service-Provider Network

Service providers control WANs to offer connectivity to singular users or organizations. They may provide simple connectivity, by way of leased lines, or higher level, managed services to enterprises. Service providers also provide Internet and cellular connectivity to their consumers.
