What are the three major operations that computer hardware and software accomplish? Provide a brief explanation of each operation.

What will be an ideal response?

Input-Hardware devices that perform input operations include keyboards and mice.
Through these devices, data, or facts, enter the computer system.
Processing-Processing data items may involve organizing them, checking them for
accuracy, or performing mathematical operations on them. The hardware component
that performs these types of tasks is the central processing unit, or CPU.
Output-After data items have been processed, they become information. Information
often is sent to a printer, monitor, or some other output device so people can view,
interpret, and use the results. Sometimes, you store output on hardware, such as a
disk or flash media that holds information for later retrieval as input for another
program.
