II What is a Network?
To understand what a network is about we must understand topologies, design and structure as well as infrastructure of a network. This course is designed to provide a solid introduction to the concepts and terms required of basic network administration.
A network is a collection of two or more devices connected for the purpose of sharing resources. Devices can include computers, printers, fax machines, and Internet communication hardware. In addition to hardware devices, software is also used to provide additional capabilities such as security (the privacy and protection of network traffic) and enhanced services such as Internet browsing, print queue management, etc. These devices can be connected via wires (cables) or wireless technologies (radio or infrared).
