Final answer:
The correct answer is 'A. Distributed system,' which is a network of loosely coupled processors that collaborate to complete tasks. Microprocessors within these systems serve as CPUs performing various functions.
Step-by-step explanation:
The correct answer to the question is 'A. Distributed system.' A distributed system is indeed a collection of loosely coupled processors that are interconnected by a communications network. This type of system allows for multiple processors to collaborate on a task distributed across different locations, yet acting in unison to achieve a common goal. The processors work together by sending messages to each other over the network to share data and coordinate actions.
A microprocessor is an integrated circuit that contains the functions of a computer's central processing unit (CPU). It is capable of performing a variety of functions by executing stored sequences of instructions called programs. These microprocessors become the computing core in a distributed system, working together to process and manipulate data effectively.
