Which term describes the communication pathways on a motherboard between the CPU and memory?

• A. Buses
• B. ROM
• C. RAM
• D. Chips

Answer: (A)

The idea being tested is how components talk to each other inside a computer. The pathways that carry data, addresses, and control signals between the CPU and memory are called buses. They are the actual channels that allow the processor to fetch instructions and data from memory, send the location it wants to read or write, and control when those actions happen. Without these pathways, the CPU wouldn’t be able to access memory efficiently. ROM and RAM are types of memory, not the communication channels between CPU and memory, so they don’t describe how the CPU talks to memory. Chips is a broad term for integrated circuits, not the specific pathways that connect CPU and memory.
