Transmission Modes

The transmission mode reflects the way data is being transmitted to the systems. The binary data that we sent during transmission can be sent in two different modes : Parallel and Serial

Parallel Transmission

The binary data is of fixed length and it is divide into the groups. The sender ans the receiver are connected in parallel fashion with same number of data lines.

The sender and the receiver computer distinguish between the high and low order data  lines. The sender sends all the bits at once.

Serial Transmission

In serial transmission, bits are sent one after another in a queue manner. Serial transmission requires only one communication channel.

Serial transmission can be either asynchronous or synchronous.
