The correct answer is: D. Real-time processing
Real-time processing is a type of processing that produces output results immediately after input data are entered into a computer system. It is used in applications where it is important to have up-to-date information, such as in air traffic control, stock trading, and medical diagnostics.
Time-sharing is a type of processing in which multiple users share a computer system. Each user is given a small amount of time to use the computer, and then the computer switches to the next user. This type of processing is used in applications where it is important to have multiple users be able to access the computer at the same time, such as in an office environment.
Interactive processing is a type of processing in which the user interacts with the computer in real time. The user enters data and commands, and the computer responds immediately. This type of processing is used in applications where it is important for the user to be able to see the results of their actions immediately, such as in a word processing program.
Batch processing is a type of processing in which data is collected and then processed at a later time. This type of processing is used in applications where it is not necessary to have the results immediately, such as in payroll processing.
E. None of the above is not a valid option.
