Connectivity is capability of computer to share information with other computers. The concept of connectivity common used in network. Network can be set up based on the user's needs. Computer network is a communication system which connect two or more computers to allow exchange of information and data and share resources. There are four basic elements in a communication system.
There are some specialized terms to describe computer network.
There are six network types : LANs
Home Network
Wireless LAN
Personal Area Network
MANs (metropolitan area network)
WANs (wide area networks)
Wireless devices are getting develop rapid and most spread used nowadays, for example tablets, smartphones and wearables. They apply the wireless revolution which is a revolution that will dramatically affect the way we communicate and use computer technology. Bandwidth is a measurement of the width or capacity of the communication channel. Effectively, it means how much information can move across the communication channel in a given amount of time. For example, the text documents transmit through a short bandwidth but video and audio need a wider bandwidth to transmit. There are four types of bandwidth :
Protocol is a communication rules for exchanging data and information between computers. There are two essential features for protocol :
