Computer Fundamentals and System Concepts Questions
-
linear control system
-
peripheral equipment
-
multiprocessing
-
controlling system
-
operating system
E
Correct answer
Explanation
An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs.
-
Cache
-
ALU
-
Swap space
-
Video card
-
Motherboard
B
Correct answer
Explanation
In computing, an arithmetic and logic unit (ALU) is a digital circuit that performs integer arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers.
B
Correct answer
Explanation
The 8086 is a 16-bit microprocessor chip designed by Intel between early 1976 and mid-1978, when it was released.
-
General purpose registers
-
Conditional registers
-
Address registers
-
Status register
-
Program counter
E
Correct answer
Explanation
The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is a processor register that indicates where a computer is in its program sequence.
-
Virtual memory
-
CPU modes
-
System call
-
Page Table
-
Overlay
B
Correct answer
Explanation
CPU modes are operating modes for the central processing unit of some computer architectures that place restrictions on the type and scope of operations that can be performed by certain processes being run by the CPU. This design allows the operating system to run with more privileges than application software.
-

-
instructions
-
digital signals
-
data
-
address
-
none of the above
B
Correct answer
Explanation
Micro programs are written to execute the OPCODE of the instruction. Epodes are identified, and then appropriate signals for registers, accumulator, program counter, etc. are generated. These are digital signals.
-
faster than CISC
-
same as CISC
-
slower than CISC
-
cannot compare the two technologies
-
none of the above
C
Correct answer
Explanation
Micro programs slow down the processing speed due to overheads attached with accessing them compared to direct hardware execution as done in CISC.
