Document Summary
Network is a group of computers and other devices (such as printers) that are connected by some type of transmission media. Network can be small as two computers connected by a cable or as large as several thousands computers connected across the world via a combination of cables, phone lines, cellular links. Networks can link mainframe computers, printers, plotters, fax machines, phone systems. Networks can communicate through copper wires, fiber optic cable, radio waves. Networks allow you to manage, administer, resources on multiple computers from a central location, network increases productivity. Simplest form; every computer can communicate directly with every other computer. No computer on a peer-to-peer network has more authority than another. Each computer can be configured to share some of its resources. Often less expensive to set up and maintain. Not practical for connecting more than a handful of computers because they do not always centralize resources (disadvantages)
