Differentiate between asynchronous and synchronous mode of data transmission.

Asynchronous and synchronous data transmission are methods of transferring data between devices.

Asynchronous Transmission:

• Timing: Data is sent at irregular intervals with start and stop bits.
• Synchronization: Each byte is independently synchronized with start (usually a 0 bit) and stop (usually a 1 bit) bits.
• Efficiency: Lower efficiency due to extra bits for synchronization.
• Example: Serial communication in keyboard data transfer.

Synchronous Transmission:

• Timing: Data is sent at regular intervals, synchronized by a clock signal.
• Synchronization: Continuous stream of data with synchronization handled by the clock signal.
• Efficiency: Higher efficiency since no start and stop bits are required.
• Example: Network communication like Ethernet.

Key Differences:

• Asynchronous uses start/stop bits for each byte, while synchronous relies on a continuous clock signal.
• Synchronous is more efficient and suitable for high-speed data transfer.
