(B) Motherboard
Here’s a breakdown of why the other options are incorrect:
- (A) Central Processing Unit (CPU): The CPU is a single chip, not a board, and it’s just one of the components found on the motherboard.
- (C) Random Access Memory (RAM): RAM is another component that plugs into the motherboard, not the motherboard itself.
- (D) Hard Disk Drive (HDD): The HDD is a separate storage device that connects to the motherboard via cables.
The motherboard acts as the central hub of communication for all the components in your computer. It allows the CPU, memory, graphics card, storage drives, and other peripherals to communicate with each other and share data.
