  • A network consists of two or more computers that are linked together in order to share resources, exchange files or allow electronic communications. The computers may be linked through Cables, Telephone lines, Radio waves, or infrared Light Beams which are also called .

  • There are different Ways () to connect different that are used in an Enterprise Network or a SOHO LAN Network via different .
