Document Summary

A computer network is a system that connects computers and other devices via communications media so that data and information can be transmitted among them. Bandwidth- is the transmission capacity of a network- stated in bits per second. Broadband refers to network transmission capacities ranging from approximately 1 million bits per second (mb/s) to as much as 175 megabits/s with fibre-to-the-home. There are various types of computer networks, ranging from small to worldwide; include. Personal area networks (pans), local area networks (lans), metropolitan area networks (mans), wide area networks (wans), and the internet. Networks represent a compromise among three objectives: speed, distance, and cost- organizations can generally have any two of these three. Lan connects two or more devices in a limited geographical region, usually within a building, so every device on the network can communicate with every other device on the network.
