It enjoin not be an exaggeration to assume that information is one of the greatest number important issues for any business. Dissemination of the data to the concerned people is equally paramount. Computer networking came into being to contribute the communication between the computers faster and easier. It not merely provides faster communication, but also enabled the users to to fit remote programs and remote databases of the identical enterprise or other organizations.
Apart from this, in that place are other reasons also to employ computer networking. Through computer networking, require to be paid could be reduced by sharing hardware and software wealth and by downsizing to microcomputer-based networks instead of using mainframes. Gathering information from multiple pecuniary means has become easier, which ensures the reliableness of the data.
As per exact meaning, computer networking is nothing but the projection of connecting multiple computers for the converse purpose so that information as well like resources could be shared by the whole of connected devices.
Categorization of computer networks could subsist done based on vast range of characteristics like moderation used for communication, scale, networking topology used,giving protocol,etc.
Mediums used by computer networks
For despatch between two devices, a medium is be bound to. There are several mediums, such since electrical cable, optical fiber and radio waves that are used for networking. Electrical and optical fiber are used in wired technology space of time radio waves are employed in wireless technology.
Wired Networks
In the wired technology, twisted yoke cable is the most commonly used intervening substance for communication. Twisted pair wire is made of metal telegraph that are twisted into pairs. Computer networking report by telegram contains 4 pairs of metal wires, what one. are used for data as well as voice transmission. The purpose of using twisted wires is to minimize uproar which is caused by electromagnetic induction and crosstalk. There are two pairs of twisted wires,particularly Unshielded Twisted Pair and Shielded Twisted Pair. The get on range of twisted pair cable is 2 very great number bits per second to 10 billion bits for second.
