WHAT IS A WAN SERVICE AND HOW DOES IT WORK – CONNECTING THE WORLD BEYOND IMAGINATION

WAN or extensive area network is a type of network provider that allows transmission of data, images, audio, or video over a large scale of geographical area. It is made through a combination of local area networks also known as LAN and the MAN network. This allows the user’s computer from one specific geographical area to communicate with other computers in another geographical area. It is supplemented by a private or public network or transmission system. Data transmission is carried out with the aid of hubs, switches, fiber optics, modem and routers. Technologies involved in data transfer from one computer to another over the internet are as follows: ISND: integrated services digital network SMDS: switched multi-megabit data server SONET: synchronous optical network HDL
