A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
The first assignment in understanding how to build a computer network is defining what a network is and understanding how it is used to help a business meet its objectives. Network is a combination of computer hardware, cabling, network devices, and computer software used together to allow computers to communicate with each other. A network is basically all of the components (hardware and software) involved in connecting computers across small and large distances. Networks are used to provide easy access to information, thus increasing productivity for users.
