digital computer
-
analog computer
-
hybrid computer
-
machine-in-built computer
-
None of these

-
control unit
-
CPU
-
register
-
memory
-
None of these
C
Correct answer
Explanation
Registers are small, high-speed storage locations within the CPU used for specific, immediate tasks, often protected or reserved for internal operations.
-
management
-
processing
-
utility
-
application
-
None of these
D
Correct answer
Explanation
System software, such as the operating system, acts as an interface between the computer hardware and the application software, allowing them to communicate and function together.
-
basic input/output system
-
secondary input/output system
-
peripheral input/output system
-
marginal input/output system
-
None of these
A
Correct answer
Explanation
The Basic Input/Output System (BIOS) is firmware used to perform hardware initialization during the booting process and provides runtime services for operating systems and programs to interact with peripherals.
-
The platform
-
Application software
-
Operating system
-
The motherboard
-
None of these
C
Correct answer
Explanation
The operating system is the primary system software that manages computer hardware and software resources and provides common services for computer programs, including the user interface.
-
transistor
-
resistor
-
integrated circuit
-
semiconductor
-
None of these
C
Correct answer
Explanation
An integrated circuit, often called a chip or microchip, is a set of electronic circuits on one small flat piece of semiconductor material, usually silicon.
-
Boot-sector viruses
-
Macro viruses
-
Time bombs
-
Worms
-
None of these
C
Correct answer
Explanation
Time bombs are a type of malware designed to execute their malicious payload only when a specific date or time is reached. Other viruses, like boot-sector viruses, are triggered by different events.
-
spyware
-
adware
-
spam
-
malware
-
None of these
D
Correct answer

-
command - based user interface
-
GUI
-
system utility
-
API
-
none of these
B
Correct answer
Explanation

-
System software
-
Operating system
-
System operations
-
None of these
B
Correct answer
Explanation

None of the above
C
Correct answer
Explanation
An operating system is the primary software that manages computer hardware, software resources, and provides common services for computer programs.
-
hardware
-
peripherals
-
memory
-
screen
A
Correct answer
Explanation
