Media is a broad term used to define the system of storage and transfer of information from one point to another. The attempt to communicate ideas resulted in the development of writing. This later gave way to the printing media, electronic media and the computer media in the present age. Printing media like magazines and newspapers were able to convey news to the immediate vicinity and also to extended areas, but within limits. Electronic media revolutionized the life of people. The role of electronic media is not limited to just the transfer of data. It has its applications in the everyday life of man, though attention has been shifted recently to the computer based system.
