Angelina Answer / Solution
Some basic difference between Synchronous and Asynchronous Transmission are :
In Synchronous transmission, Data is sent in form of blocks or frames and in asynchronous transmission, Data is sent in form of byte or character.
Synchronous transmission is fast and Asynchronous transmission is slow.
Synchronous transmission is costly and Asynchronous transmission is economical.
In Synchronous transmission, time interval of transmission is constant and In asynchronous transmission, time interval of transmission is not constant, it is random.
In Synchronous transmission, There is no gap present between data and In asynchronous transmission, There is present gap between data.
Efficient use of transmission line is done in synchronous transmission and While in asynchronous transmission, transmission line remains empty during gap in character transmission.
Synchronous transmission needs precisely synchronized clocks for the information of new bytes and Asynchronous transmission have no need of synchronized clocks as parity bit is used in this transmission for information of new bytes.
