Explanation / Answer
A Protocol is a set of rules which govern how data is sesnt from one point to another. It establishes a means of communication between two systems.
The protocols for data transfer can be grouped into two types: Synchronous and Asynchronous.
Synchronous Protocols:
In synchronous transmission, data flows in a full duplex mode in the form of bkocks and frames. Synchronization btween sender and receiver is necessary (i.e. a clock between transmitting and receiving devices should be running at same rate) so that sender know where the new byte starts. It is efficient, reliable and is used for transferring a large amount of data. Greater efficiency is acheived by grouping characters together and doing away with start and stop bits (see asynchronous protocol) for each character, these are replaced by a new format that permits flexibility by using a start type sequence called header and a stop type sequence called a tail.Synchronous protocols are either character oriented protocol or bit oriented protocol.
An example of its use in place of work- Online Conferencing.
Asynchronous Protocol:
Asynchronous systems send data bytes between the sender and receiver by packaging a data in an envelope. It transmits data in continous stream of bytes and character sent is 8 bits to which a parity is added, a new start and stop bit that gives the total of 10 bits. It does not requires a clock for synchronization. It has slower rate of data transfer and therefore synchronous protocol is preferred over it.
