transmission media in computer network

                  transmission media in computer networks

In this article today learn transmission media in computer networks there are two parts divided transmission media in computer networking. this part covers a  transmission media Introduction.

transmission media :

 on any network, the various entities must communication thought some form of media gift for women's can communicate thought telephone wires or sound waves in the air computer can communication thought table light and radio waves transmission media in computer to send and receive a message do not guarantee that the message will be understood.

 transmission media makeup possible the transmission of electronic signals from the computer to another computer electronic signals Express data values in the form of the binary data value in the form of binary improves the signals are transmitted through the network using the combination of electronic device and transmission media reach the desired definition of a computer.

 1 bandwidth:

 when is the maximum frequency range that can be  practically buy  media this is usually expressed in kilo Hz aur Mega Hz, for example, analog transmission of human speech bandwidth of  4 k h Z related is the notation of data rate which denotes the maximum number of bytes per second  transmitted for example a data rate of 10 MBPS means  that 10 million bytes per second can be transmitted.

 2.  cost :

 two types of cost are irrelevant

 a cost of installing the media including the medium-specific equipment that may be needed and

b  the cost of running and maintaining the medium and its equipment  is usually a need for a trade-off between cost bandwidth and distance.

3. reliability :

 some media by their physical nature transmit data more reliably than other Laura liability to a higher number of errors which needs to be balanced against the potential recovering from the error.

 design factors for transmission media

 bandwidth other factor remaining constant the bandwidth of a signal the higher the data rate that can be achieved.

 improvements limit the distance a signal can travel
