A
Correct answer
Explanation
A notebook computer is a portable personal computer that is typically lightweight and compact, often weighing around 6 pounds or less.
-
Initialization of programs
-
Starting the system
-
Starting and loading of OS programs for execution
-
None of the above
C

-
Several million
-
Million
C
Correct answer
Explanation
Pentium processors contain millions of transistors, ranging from about 3 million in early versions to much more in later versions. 'Several million' is the most accurate description. One or one hundred transistors is far too few for a CPU.
A
Correct answer
Explanation
The Arithmetic Logic Unit (ALU) is the component of a CPU that performs arithmetic operations like addition. While ALUs can add any numbers, binary addition (adding 2 numbers) is fundamental to how computers process information. The other options (4, 5, 6) are not standard ways to describe ALU functionality.
-
Program error
-
Hard Disc
-
Both (1) and (2)
-
None of the above
A
Correct answer
Explanation
A hardware interrupt is triggered by external hardware devices (like a hard disk or keyboard). A program error (like division by zero) triggers a software interrupt or exception, not a hardware interrupt.
-
Computer organisation
-
Hardwired control
-
Control word
-
Either control word or computer organisation
-
None of these
B
Correct answer
Explanation
In hardwired control, all the control signals required inside the CPU can be generated using a state counter and a PLA circuit.
-
Allocation
-
Linking
-
Relocation
-
Either Allocation or Relocation
-
None of these
B
Correct answer
Explanation
This is a process that resolves external symbolic references by linking need object modules, which are referenced in the program.
