Detailed explanation-1: -Explanation: This mode of transmission is suitable for multiple device situation as it supports variable speed transfer. The asynhronous BUS mode of transmission allows for a faster mode of data transfer.
Detailed explanation-2: -asynchronous bus A bus that interconnects devices of a computer system where information transfers between devices are self-timed rather than controlled by a synchronizing clock signal. A connected device indicates its readiness for a transfer by activating a request signal.
Detailed explanation-3: -Explanation: The asynchronous transmission is termed as Hand-Shake transfer because the master intimates the slave after each step of the transfer.
Detailed explanation-4: -Asynchronous data is data that is not synchronized when it is sent or received. In this type of transmission, signals are sent between the computers and external systems or vice versa in an asynchronous manner.
Detailed explanation-5: -Synchronous transmission is faster, as a common clock is shared by the sender and receiver. Asynchronous transmission is slower as each character has its own start and stop bit.
