Question 41
A
Diligence
B
I.Q.
C
Accuracy
D
Versatility
Explanation
The Computer system has no I.Q. of its own. It does only what it is programmed to do. It cannot take decisions of its own. A computer is diligent, because it can work continuously for hours without getting any errors or without getting grumbled. Accuracy of a computer is consistently high and its level of accuracy depends on its design. A computer can perform any task if, it can be broken down into a series of logical steps. Therefore, a computer is versatile.

A
Input Unit
B
Memory Unit
C
Control Unit
D
I/O Unit
Explanation
The control unit manages and coordinates the operations of a computer system. The ALU is responsible for performing all the arithmetic and bitwise operations . Therefore, both these units combine to form the brain of the computer ,which is the central processing unit.

Question 43
A
Data path
B
Controller
C
Registers
D
Cache
Explanation
A processor is a part of the computer which does all the data manipulation and decision making. A processor comprises of: A data path which contains the hardware necessary to perform all the operations. A controller tells the data path what needs to be done. The registers act as intermediate storage for the data.

Question 46
A
State Table Method
B
Delay Element Method
C
Sequence Counter Method
D
Using Circuits
Explanation
There are 3 ways of implementing hardwired control unit: A state table is the simplest method in which a number of circuits are designed based on the cells in the table. A delay element method consists of a flowchart drawn for the circuit. A D-flip flop is used as a delay element. A sequence counter method used k-modulo counter as a replacement for k delay elements.

A
Program
B
Command
C
Micro program
D
Micro command
Explanation
For every micro-operation, a set of microinstructions are written which indicate the control signals to be activated. A set of microinstructions is a micro program. The address of the next microinstruction is given by a Microprogram counter.

Question 48
A
True
B
False
Explanation
The computer understands only binary language. So, the microprogram should have instructions which are in the form of 0s and 1s. Each output line of the micro-program corresponds to one control signal.

Question 49
A
Vertical Microinstruction
B
Horizontal Microinstruction
C
Multilevel Microinstruction
D
All types of microinstructions
Explanation
There are two types of microinstructions: Horizontal and Vertical. In a horizontal microinstruction, each bit represents a signal to be activated whereas, in case of a vertical microinstruction bits are decoded and, the decoder then produces signals
