Assignment

Question_1: [marks: 15]
What is the difference between serial and parallel transfer? Explain how to convert serial data to parallel and parallel data to serial. What type of register is needed?


Question_2: [marks: 5]
How can a serial in/parallel out register be used as a serial in/serial out register?



Note: Provide to-the-point answer.

[Xpert]

Serial type data is that goes in once it can be seen that we send some thing in one way. which is either going or coming. But in parallel we can see that it can come and go at the same time. Like half duplex and full duplex. Actually the serial is like simplex. it goes one way. Like door bell. Which is going one way don't have incoming. I hope this idea is good for the first question answer.

Second answer

[Xpert]

A serial-in/parallel-out shift register is similar to the serial-in/ serial-out shift register in that it shifts data into internal storage elements and shifts data out at the serial-out, data-out, pin. It is different in that it makes all the internal stages available as outputs. Therefore, a serial-in/parallel-out shift register converts data from serial format to parallel format. If four data bits are shifted in by four clock pulses via a single wire at data-in, below, the data becomes available simultaneously on the four Outputs QA to QD after the fourth clock pulse.



Second question reference is taken from
Serial-in, parallel-out shift register : SHIFT REGISTERS (http://www.allaboutcircuits.com/vol_4/chpt_12/4.html)
