What is serial data transfer? Write the difference between synchronous and asynchronous data

transfer.

(a) What is the difference between microprocessor and microcontroller? Describe how data can

flow between microprocessor, memory and I/O devices.

(b) Data byte 28H is stored in register B and data byte 97H is stored in the accumulator. Show the

contents of registers B, C, and the accumulator after the execution of the following instructions:

(a) MOV C, A (b) MOV A, B (c) ADD B

(c) Calculate the square of the contents of memory location 9100H using look-up table and place

the result in memory location 9501.
