Functions of A Wide Area Network

Introduction WAN is a geographically dispersed telecommunications network. This term distinguishes wider telecommunications structures from local area networks. Wide area networks can be privately owned or rented, but this term usually means including PSTN. Geographically, the intermediate form of the network is the metropolitan area network. WAN is a regional or global communication network within a geographical region with a normal distance between major metropolitan areas.

Wide area network (WAN) is a computer network spanning a wide geographic area. A wide area network usually consists of two or more local area networks (LANs). A computer connected to the WAN is usually connected via a public network such as a telephone system. It can also be connected via private line or satellite. An example of a wide area network is the Internet, which is the largest existing network. WAN technology usually functions in the lower three layers (physical, data link, and network layers) of the OSI reference model.

With a computer network, devices and endpoints can connect to each other and to large networks such as the Internet on a local area network (LAN) or a private wide area network (WAN). This is a fundamental function for global service providers, businesses, and consumers to share resources, use or provide services, and communicate services. Convenience of network, such as text messaging from telephone, streaming video to mono Internet (IoT). The level of skill required to operate a network is directly related to the complexity of a particular network. For example, in large enterprises, there are thousands of nodes and because of strict security requirements such as end-to-end encryption, dedicated network administrators need to monitor the network.

A computer network designer can operate a local area network, a wide area network, or an intranet. Computer network designers are planning to maintain and update computer networks to ensure that the network is functioning effectively and that the technology is up-to-date. Individuals in this field can work at a computer network service company or work directly at a specific company or organization. Computer technical support experts use computer system, general knowledge of hardware and software, and specific product knowledge to mitigate technical problems. Some people in this field work for a technical support service company but others work at a company or institution. Computer technical support experts need to maintain current understanding of current technical and technical problems.
