Introduction

The following paper is a report into the characteristics and locution of a Wide Area Network (WAN). It will go about by giving a basic description of a Wide Area Network and then go on to investigate, in detail, the actual structure and workings of a WAN. The mean purpose of the report is to allow individuals with or without prior intimacy of the researched atomic number 18a to have better understanding of the report subject.

Basic Concepts

Characteristics of a WAN

The term WAN (Wide Area Network) refers to a network, which covers a wide geographical area, and use communications circuits to connect the intermediate nodes. WANs are utilize across a city, country or still around the globe. Typical transmission rates are 2 Mbps, 34 Mbps, 45 Mbps, 155 Mbps, and 625 Mbps but can be even more than this. A WAN consists, basically, of two or more LANs (Local Area Network), which are connected to each opposite using WAN technologies under a high-speed communication. The largest and believably the best example of a Wide Area Network is the Internet. WAN technologies generally function at the lower three layers of the OSI Model: the Physical socio-economic class, the Data Link Layer, and the Network Layer (all layers are shown in order below). . Bridges, routers and multiplexers and other devices are used for correct information transmission.



Some WANs are extremely widespread (global), but most do not provide true global coverage. Organizations supporting WANs using the Internet Protocol are known as Network Service Providers (NSPs). These form the effect of the Internet.

Addressing and routing

On a Wide Area Network, the routing of data is done mainly using TCP/IP (Transmission crack protocol/Internet Protocol).
