Q1. What is difference engine? Briefly explain the structure of Babbage’s Difference Engine. 4+6 =
10
Answer: Difference Engine: The difference engine was designed to calculate the entries of a table
automatically and transfer them via steel punches to an engineer’s plate from which the tables could
be printed. The only arithmetic operation performed by this machine was addition. However using a
mathematical technique called method of finite difference, a large number of
Q2. What is the difference between fixed and floating point numbers? 5+5 = 10

Q4. Briefly explain the read and write cycle of an 8086 processor. 5+5 = 10
Answer: After understanding of the instruction cycle of the processor, now let us learn about the
Read-Write cycles. Read Cycle is Data Transfer from Memory or Input/output (I/O) to CPU.
Q5. Briefly explain Interrupt Driven I/O. 10
Answer: Interrupt Driven I/O

2. Using Program-controlled I/O requires continuous involvement of the processor in the I/O activities.
It is desirable to avoid wasting processor execution time. An alternative is for the CPU to issue an I/O
command to a module and then go on other work. The I/O module will then
Q6. Describe Multiprocessing. Briefly explain its system. 5+5= 10
Answer: Multiprocessing is concerned with the capability of a computer system to provide support
to more than one processor or the capability to accomplish more than one program simultaneously.
