What does part number, part description and number of parts ordered belong to?
Answer: B
Correct answer: Input
Part number, description and quantity ordered are the data supplied to the system before anything is computed, so they are its input. Output would be the resulting order or invoice, and feedback and control belong to the monitoring of the process.

Which term is associated with the comparisons of processing speeds of different computer system?
Answer: B
Correct answer: MIPS
MIPS - millions of instructions per second - is the figure quoted when processing speeds are compared. CPS is characters per second, a printer measure, and MPG belongs to motor cars.

CPU is mainly responsible for
Answer: C
Correct answer: Both 1 and 2
Processing the data is what the CPU does, and calculation is the largest part of that processing. The two options are not alternatives but the general description and its chief instance.

What is the use of control unit of a microprocessor?
Answer: B
Correct answer: To decode instructions and generate control signals
The control unit fetches each instruction, decodes it, and issues the timing and enable signals that make the other units carry it out. Arithmetic and logic are performed by the ALU, storage by memory, and input by the input devices - the control unit directs them all without doing any of their work itself.

What do you mean by the term “gigabyte”?
Answer: C
Correct answer: 1024 megabytes
Each step in the binary sequence multiplies by 1024: 1024 bytes make a kilobyte, 1024 kilobytes a megabyte, and 1024 megabytes a gigabyte.

With the help of microprocessor what can be made?
Answer: D
Correct answer: All of the above
A microprocessor is a general purpose processing element, so it serves wherever computation is needed - in a pocket calculator, in a computer, and in the embedded digital systems inside appliances and instruments.

In the CPU of a computer, the logical unit is mainly responsible for
Answer: B
Correct answer: Comparing numbers
The logic half of the ALU performs comparisons and Boolean operations - equal, greater than, AND, OR - and it is those comparisons that make branching possible. Arithmetic belongs to the other half, and controlling the flow of information is the control unit's work.

What do you mean by the simultaneous processing of two or more programs by multiple processors?
Answer: C
Correct answer: Multiprocessing
Multiprocessing means two or more processors executing programs at the same instant, which is what the question describes. Multiprogramming and time sharing keep several programs in memory but interleave them on a single processor, so only one instruction is executing at any moment.

When is the job processed by the computer?
Answer: A
Correct answer: During execution time
A job is processed while it is executing - that is what execution means. Delay and down time are periods in which nothing is processed, and real time describes a class of system rather than a period.

Which of the following statement is valid?
Answer: B
Correct answer: 1KB = 1024 bytes
The binary prefixes step by 1024, so a kilobyte is 1024 bytes and a megabyte is 1024 kilobytes, or 1,048,576 bytes. The options giving 1000 bytes to the kilobyte and 1024 bytes to the megabyte both break that sequence.
