Study Notes
Computer System Components
- A computer system consists of both hardware and software components, which are crucial for its operation.
- Hardware provides the physical infrastructure necessary to run the system, while software provides the instructions that the hardware executes.
Hardware Components
- Major components of a computer include:
- Motherboard
- Power Supply Unit (PSU)
- Central Processing Unit (CPU)
- Memory (RAM)
- Storage Devices
- Graphics Processing Unit (GPU)
- Input and output Devices
Motherboard
- The motherboard is the primary circuit board inside a computer system, connecting all components together.
- Components of a motherboard include:
- CPU Socket
- RAM Slots
- BIOS/UEFI Chip
- Expansion Slots (PCI, PCIe, AGP)
- Input/Output (I/O) Panel
Power Supply Unit (PSU)
- The PSU converts AC power from the wall outlet to DC power for the computer's components.
Central Processing Unit (CPU)
- The CPU is the primary computational engine of a computer, executing instructions and performing arithmetic, logical, and input/output operations.
- Components of a CPU include:
- Arithmetic Logic Unit (ALU)
- Control Unit (CU)
- Registers
- Cache Memory
Input/Output (I/O) Panel
- The I/O panel contains ports for external connections, including:
- USB ports
- Audio jacks
- Display ports (HDMI, VGA, DisplayPort)
- Ethernet ports
- Legacy ports (PS/2)
Types of Computer Ports
- Serial port: used to connect older devices, such as modems and printers.
- Parallel port: used to connect older devices, such as printers.
