The correct answer is: A. batch processing
Batch processing is a type of data processing where a series of programs are run in sequence, without any user interaction. This was the dominant form of computer usage in the early days of computing, when computers were large and expensive, and time on them was very limited.
Interactive processing is a type of data processing where the user interacts with the computer in real time. This is the dominant form of computer usage today, as computers have become smaller, faster, and more affordable, and users have come to expect a high level of interactivity.
Parallel processing is a type of data processing where multiple processors work on a problem at the same time. This can be used to speed up the processing of large or complex problems.
Random processing is a type of data processing where the order in which programs are run is not predetermined. This can be used to handle unpredictable or time-critical tasks.
Multi-task processing is a type of data processing where multiple programs are run at the same time. This can be used to improve the overall performance of a computer by allowing multiple tasks to be completed simultaneously.
I hope this helps!
