Data Transmission

Question 1

Define parallel data transmission.

Answer 1

Transmission of several bits at one time over multiple buses.

Question 2

Define serial data transmission.

Answer 2

Transmission of one bit at a time.

Question 3

Define synchronous data transmission.

Answer 3

Tx and Rx computers operate at the same clock speed and send/transmit at same speed.

Question 4

Define asynchronous data transmission.

Answer 4

Tx and Rx computers operate at different clock speeds and send/transmit at different speeds. Clock speed of receiving computer changes temporarily during packet recieval.

Question 5

What are the 3 modes of data transmission?

Answer 5

Simplex, Half Duplex and (Full) Duplex.

Question 6

Explain Simplex data transmission.

Answer 6

Data can only be transmitted in one direction.

Question 7

Explain Half-Duplex data transmission.

Answer 7

Data can only be transmitted in one direction AT ANY GIVEN TIME.

Question 8

Explain Full-Duplex data transmission.

Answer 8

Data can be transmitted both ways at the same time.
