What is the Difference Between Synchronous and Asynchronous Transmission?
🆚 Go to Comparative Table 🆚Synchronous and asynchronous transmission are two types of data transmission methods used in communication systems. Here are the main differences between them:
- Data transfer format: In synchronous transmission, data is sent in the form of frames or blocks, while in asynchronous transmission, data is sent in the form of bytes or characters.
- Clock synchronization: Synchronous transmission requires a common clock between the transmitter and receiver, ensuring that data is transmitted in fixed intervals. In asynchronous transmission, a clock signal is not needed because each character contains its own start and stop bits, which serve as a start indicator of the new byte.
- Transmission speed: Synchronous transmission is faster than asynchronous transmission, as it transmits data in chunks rather than one byte at a time.
- Cost: Synchronous transmission is more expensive than asynchronous transmission, which is more cost-effective.
- Gaps between data: In synchronous transmission, there is no gap between the data, while there is a gap between the data in asynchronous transmission due to the start and stop bit feature.
- Efficiency: Synchronous transmission is more efficient and reliable than asynchronous transmission for transferring large amounts of data.
- Transmission line usage: In synchronous transmission, efficient use of transmission lines is achieved, while in asynchronous transmission, the transmission line remains empty during a gap in character transmission.
In summary, synchronous transmission is more suitable for transferring large amounts of data quickly and efficiently, while asynchronous transmission is more suitable for sending small amounts of data cost-effectively.
Comparative Table: Synchronous vs Asynchronous Transmission
Here is a table comparing the differences between synchronous and asynchronous transmission:
Feature | Synchronous Transmission | Asynchronous Transmission |
---|---|---|
Data transmission | Sent in blocks or frames, continuous stream of data | Sent in bytes or characters, one byte at a time |
Synchronization | Requires synchronization between sender and receiver | No synchronization required between sender and receiver |
Clock signal | Needs an external clock signal to synchronize data at the receiver | Does not need an external clock signal, relies on internal clock and start/stop bits |
Data transfer rate | Faster, transmits in chunks of data | Slower, transmits one byte at a time |
Efficiency | More efficient, no gaps between data | Less efficient, gaps between data |
Cost | More costly, requires additional channels for clock signals | Less costly, no additional channels needed for clock signals |
Use case | Suitable for transmitting large amounts of data, such as text files | Suitable for transmitting small amounts of data, such as individual characters |
Synchronous transmission requires synchronization between the sender and receiver, and data is sent in blocks or frames with no gaps between them. This method is more efficient and faster than asynchronous transmission, which is suitable for transmitting large amounts of data.
Asynchronous transmission, on the other hand, does not require synchronization. Data is sent one byte at a time, with gaps between the data. This method is less efficient and slower than synchronous transmission, but it is more cost-effective and suitable for transmitting small amounts of data.
