Question
Which type of shift register can be utilized for longer distance communication ___________
- a. PIPO
- b. SIPO
- c. PISO
- d. SISO
Clear my choice
Solution
The type of shift register that can be utilized for longer distance communication is b. SIPO (Serial In Parallel Out).
Here's why:
-
In a PIPO (Parallel In Parallel Out) shift register, all data bits are input and output simultaneously which is not suitable for long distance communication.
-
In a SIPO (Serial In Parallel Out) shift register, the data bits are input serially one after the other and are output in parallel. This makes it suitable for long distance communication as it can transmit data bit by bit over a single line.
-
In a PISO (Parallel In Serial Out) shift register, all data bits are input in parallel and are output serially which is not suitable for long distance communication.
-
In a SISO (Serial In Serial Out) shift register, the data bits are input and output serially which is also not suitable for long distance communication as it requires synchronization of both ends for each bit.
So, the correct answer is b. SIPO.
