Correct Answer: d) Processing data and instructions
Explanation: The main function of the Central Processing Unit (CPU) in a computer system is to process data and instructions. It performs arithmetic and logical operations on the data and coordinates the operations of other units within the computer system.
Q15. Which of the following is a key component of a computer system?
a) Input unit
b) Output unit
c) Central Processing Unit (CPU)
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: A computer system is composed of various interconnected units, including the input unit, output unit, storage unit, and Central Processing Unit (CPU). These units work together to process data and instructions, providing the desired output to the user.
Q16. What is the primary purpose of the storage unit in a computer system?
a) To process data and instructions
b) To store data and instructions
c) To receive input data from the user
d) To display output data to the user
Show Answer
Correct Answer: b) To store data and instructions
Explanation: The primary purpose of the storage unit in a computer system is to store data and instructions in the computer’s memory. It manages the storage and retrieval of data, ensuring that the computer has access to the necessary information for processing.
Q17. Which of the following is NOT a function of the input unit in a computer system?
a) Receiving input data
b) Converting input data into a format that can be processed by the computer
c) Displaying output data
d) Managing the flow of data and instructions between other units
Show Answer
Correct Answer: c) Displaying output data
Explanation: The input unit in a computer system is responsible for receiving input data from the user and converting it into a format that can be processed by the computer. Displaying output data is a function of the output unit, not the input unit.
Q18. Which of the following is NOT a function of the output unit in a computer system?
a) Displaying output data
b) Converting processed data into a format that can be easily understood by the user
c) Receiving input data
d) Managing the flow of data and instructions between other units
Show Answer
Correct Answer: c) Receiving input data
Explanation: The output unit in a computer system is responsible for displaying or printing the processed data on output devices, such as a monitor or printer, and converting the processed data into a format that can be easily understood by the user. Receiving input data is a function of the input unit, not the output unit.
Q19. Which of the following is a function of the Arithmetic Logic Unit (ALU) in a computer system?
a) Receiving input data
b) Displaying output data
c) Storing data and instructions
d) Performing arithmetic and logical operations
Show Answer
Correct Answer: d) Performing arithmetic and logical operations
Explanation: The Arithmetic Logic Unit (ALU) in a computer system is responsible for performing arithmetic and logical operations on the data received from the input unit or storage unit. It processes the data according to the instructions provided by the control unit.
Q20. Which of the following is a function of the Control Unit (CU) in a computer system?
a) Receiving input data
b) Displaying output data
c) Storing data and instructions
d) Managing the flow of data and instructions between other units
Show Answer
Correct Answer: d) Managing the flow of data and instructions between other units
Explanation: The Control Unit (CU) in a computer system is responsible for managing the flow of data and instructions between the input, output, storage, and processing units. It controls and coordinates the operations of other units within the computer system.
