Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Asynchronous mode of transmission is suitable for systems with multiple peripheral devices.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Asynchronous mode of transmission is suitable for systems with multiple peripheral devices. Explanation: This mode of transmission is suitable for multiple device situation as it supports variable speed transfer.

Detailed explanation-2: -In asynchronous buses, all devices connected to the bus may have different speeds and their own clocks. They use a handshaking protocol to synchronize with each other. This provides independence for different technologies and allows slower and faster devices with different clock rates to operate together.

Detailed explanation-3: -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-4: -Explanation: The data is transmitted asynchronously in RS232 which enhance long distance communication, whereas SPI, I2C offers short distance communication, and therefore, they are using synchronous data transmission.

Detailed explanation-5: -Explanation: The devices with variable speeds are connected using asynchronous BUS, as the devices share a master-slave relationship.
