Difference between synchronous bus and asynchronous bus in an input operation?

A synchronous bus operates with a clock signal that coordinates data transfer, ensuring that all components are synchronized during input operations. In contrast, an asynchronous bus does not rely on a clock signal; instead, it uses handshaking signals to manage data transfer, allowing devices to operate independently and at different speeds. This can lead to more flexible communication but may introduce complexity in timing and control. Essentially, synchronous buses provide predictability and speed, while asynchronous buses offer flexibility and adaptability.
