At the end of the session you will be able to
understand the various types of data transmission
Working of Modem and its interfaces
Types of modems
First the information transmitted from a sender to receive is encoded in a method that can be transmitted.Then we will have to discuss the ways itcan be transmitted.ie Pc will sends and receives digital signal but we have to transmit analog signals ..so some sort of conversion is needed at both ends.that has to be considered.and some devices should be there to do this.Also these devices may be of different makers and should be standardized for proper working,so there should be some rules or protocols governing the devices sending and receiving.Then we can transmit the data in many ways...bit by bit we can transmit or we can transmit the whole data simultaneously.
