Final answer:
Foreground processing in a shell that waits for a command to finish before taking another is described as synchronous. Synchronous processing executes tasks one after the other, unlike asynchronous processing which allows for concurrent task execution. So the correct answer is option A).
Step-by-step explanation:
The term that describes foreground processing where the shell waits for a command to finish before issuing the prompt for another command is A. Synchronous. In synchronous processing, tasks are performed one after another.
Each task must be completed before the next one begins, which means that the shell will not accept a new command until the current one has been processed completely. This is in contrast to asynchronous processing, where tasks can be initiated and run concurrently without waiting for prior tasks to complete. Foreground processing is when the shell waits for a command to finish before issuing the prompt for another user command.
This type of processing is synchronous. It means that the shell executes one command at a time, waiting for each command to complete before moving on to the next one. This ensures that the output of each command is displayed before the next prompt is shown.
