Difference between Synchronous and Asynchronous Transmission
Asynchronous Transmission -
In Asynchronous Transmission, data is sent in form of byte or character. This transmission is the half duplex type transmission. In this transmission start bits and stop bits are added with data. It does not require synchronization.
EX: Letters, Emails etc.
Advantages:
Synchronization between devices is not necessary.
It is a low-cost scheme.
Disadvantages:
Low transmission due to the use of 'start' and 'stop' bits and gaps between data chunks.
Timing errors take place.
Synchronous Transmission -
In Synchronous Transmission, data is sent in form of blocks or frames. This transmission is the full duplex type. Between sender and receiver the synchronization is compulsory. In Synchronous transmission, There is no gap present between data. It is more efficient and more reliable than asynchronous transmission to transfer the large amount of data.
EX: Video, Chartrooms etc.
Advantages:
Data speed is much higher because of no extra bits at the sending end and at the receiving end.
More useful for high-speed applications.
Disadvantages:
Timing is responsible for the accuracy of data.
It is required that transmitter and receiver be properly synchronized.
Key Differences Between Synchronous and Asynchronous Transmission
1. In Synchronous Transmission, data is transferred in the form of frames. On the other hand, in Asynchronous Transmission data is transmitted 1 byte at a time.
2. In Synchronous transmission, time interval of transmission is constant, whereas In asynchronous transmission, time interval of transmission is not constant, it is random.
3. Data transfer rate of Asynchronous Transmission is slower than that of Synchronous Transmission.
4. Asynchronous Transmission is simple and economical, whereas Synchronous Transmission is complicated and expensive.
5. In Synchronous transmission, There is no gap present between data, whereas In asynchronous transmission, There is present gap between data.
