Transmission Media - (2) Summary on What we have Studied on last Tutorial :- Networking involves connection of computers, workstations and peripheral devices. Wire is a single, cylindrical strand of metal conductor with low resistance to the current flow. Every cable has a limitation to carry signals only to a particular distance after which the quality of the signal degrades and becomes corrupt. As the signals travel through cables, they lose their strength. This loss of signal strength in a cable is called as attenuation. It is the amount of digital data that a cable can carry. Each type of cable can carry only a certain amount of information or data over a given period of time. Each type of cable is susceptible to some interference such as internal or external noise. It depends on the environment where the cable is to be laid. (2.1) Coaxial Cable :- Coaxial Cables consists of a solid copper core surrounded by an i...
