Study Notes
Major Hardware Components of a Computer System
- Hardware is the tangible electronic and mechanical parts of a computer.
- The system unit houses core components and is sometimes referred to as the chassis.
- The motherboard, also known as mainboard or system board, is the primary circuit board that interconnects all components and circuits.
Central Processing Unit (CPU)
- The CPU is the central "brain" of the computer, executing instructions and managing data flow.
- Notable CPU examples include Intel Core 2 Duo and AMD Athlon.
Primary Storage
- Primary storage, or main memory, temporarily holds data and processing instructions.
- It consists of RAM (volatile memory) and ROM (non-volatile memory).
- RAM loses its data when powered off, while ROM retains data regardless of power status.
Expansion Bus
- An expansion bus serves as a data pathway that connects various hardware components within or outside the computer.
- It links the CPU to other critical hardware components for efficient communication.
Adapters
- Adapters, or interface cards, are printed-circuit boards that add functionality by enabling connections to peripheral devices.
- They facilitate hardware upgrades and ensure compatibility with new devices.
Power Supply Unit (PSU)
- The PSU transforms standard AC power (120VAC) into DC voltages for use by various components within the PC.
- Located in the back corner of the PC case, it is essential for powering the system.
Hard Disk Drive (HDD)
- The HDD is a magnetic storage device used for permanent data storage within the computer.
- It plays a crucial role in the long-term retention of data compared to primary storage.
