Discussion
Assertion (A) : The CPU communicates with the memory through the address, control and data buses, forming a system bus.
Reason (R) : The system bus ensures that all components within the computer system work independently without any interconnection.
Answer: C
The answer is Assertion (A) is correct, but Reason (R) is incorrect.
The Assertion is true: the CPU exchanges information with memory over the address bus, data bus and control bus, which together form the system bus.
The Reason is false. The purpose of the system bus is to interconnect the CPU, memory and input/output devices so that they can communicate and work together, not to make them work independently without any interconnection. A false Reason rules out both options that call it correct.
