Q1. Define microoperation
and explain its types.
Answer: Microoperation: Digital modules
are best defined by the registers they contain and the operations that are
performed on the data stored in them. The operations executed on data stored in
registers are called microoperations.
Arithmetic Microoperations A microoperation
is an elementary operation performed with the data stored in registers.
The microoperations most
Q2.
Describe bus in computer system and explain its structure. 4+6
Answer:A
collection of wires through which data is transmitted from one part of a
computer to another. You can think of a bus as a highway on which data travels
within a computer. When used in reference to personal computers, the term bus
usually refers to internal bus. This is a bus that connects all the internal
computer components to the CPU and main memory. There's also an expansion bus
that enables expansion boardsto access the CPU and memory.
All
buses consist of two parts -- an address busand a data bus. The data bus
transfers actual data whereas the address bus
Q3. Explain the simple instruction format with
diagram and examples. 6+4
Answer.
Each instruction is represented
by a sequence of bits. The instruction isdivided into fields, corresponding to
the constituent elements
Q4.
Explain infinite-precision and finite-precision ten's complement.
Answer:
Infinite-Precision Ten's Complement: Imagine the odometer of an
automobile. It has a certain number of wheels,each with the ten digits on it.
When one wheel goes from 9 to 0, the wheelimmediately to the left of it
advances by one position. If that wheel alreadyshowed 9, it too goes to
0 and advances the wheel to its left, etc.Now suppose we have an
odometer with an infinite number of wheels. Weare going to use this
infinite odometer to represent all the integers.When all the wheels are 0, we
interpret the value as the integer 0.A positive integer n is represented
by an odometer position obtained byadvancing the rightmost wheel n positions
from 0. Notice that for each
Q5.
Explain the mapping functions between the main memory and CPU. 10
Answer.
Mapping functions
The correspondence between the
main memory and CPU are specified by amapping function. There are three
standard mapping functions namely
1. Direct mapping
2.
Q6.
Explain interrupt and interrupt driven I/O.
Answer:Interrupt Driven I/O:Using Program-controlled I/O
requires continuous involvement of theprocessor 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 amodule and then go on other work. The I/O
module will then interrupt theCPU requesting service when it is ready to
exchange data with the CPU.The CPU will then execute the data transfer and then
resumes its
