Questions and Answers

What is a key characteristic of synchronous transmission?

It can operate at different Baud rates for the sender and receiver.
It requires a shared clock signal between the sender and receiver. (correct)
It is commonly used in real-time systems that require asynchronous transmission.
It uses start and stop bits to indicate transmission duration.

What is the primary purpose of the start and stop bits in asynchronous transmission?

To indicate the duration of a transmission. (correct)
To provide a clock signal for the transmission.
To synchronize the Baud rate of the sender and receiver.
To ensure the transmission is received in the same order it was sent.

What type of data transmission is typically used in the fetch-execute cycle of a computer's processor?

Asynchronous transmission with a variable Baud rate.
Synchronous transmission with a shared clock signal. (correct)
Serial transmission using a single line.
Parallel transmission using multiple lines.
