(c) Hard Drive vs. RAM: RAM is volatile, short-term memory that clears when power is lost; a hard drive is non-volatile, long-term storage that keeps data permanently.

(d) Motherboard Role: It is the central circuit board that links the CPU, memory, and peripherals, allowing them to communicate and share power.

(e) Cache Memory: Cache memory is a super-fast storage space right inside or next to the processor that holds the data and instructions the computer uses most often so it can work much faster.

(f) Bus: A set of electrical lines or pathways that transport data, addresses, and control signals between the CPU, memory, and devices.
