The function of CPU is

to provide a hard copy
to read, interpret and process the information and instruction
to communicate with the operator
to provide external storage of text E. None of the above

The correct answer is: B. to read, interpret and process the information and instruction.

The CPU is the brain of the computer. It is responsible for carrying out the instructions that are stored in the computer’s memory. The CPU does this by reading the instructions, interpreting them, and then carrying them out.

Option A is incorrect because the CPU does not provide a hard copy. A hard copy is a physical copy of data, such as a printed document or a photograph. The CPU does not produce hard copies of data.

Option C is incorrect because the CPU does not communicate with the operator. The CPU communicates with the operator through the computer’s input and output devices. For example, the CPU will send a signal to the monitor to display a message, or it will send a signal to the printer to print a document.

Option D is incorrect because the CPU does not provide external storage of text. External storage devices, such as hard drives and USB drives, are used to store data that is not currently being used by the CPU.

Therefore, the correct answer is: B. to read, interpret and process the information and instruction.
