Study Notes
Internal Components of a Desktop Computer
- The power supply is a large, square component that converts AC power from the wall into DC power that is usable by the computer.
- The CPU (Central Processing Unit) is a metallic square component directly below the CPU fan and heat sink. It is responsible for processing data and instructions.
- The CPU fan and heat sink are crucial for cooling the CPU. The fan pulls heat away from the CPU and dissipates it.
- The motherboard serves as the heart of the computer. It houses the wiring and circuitry that connects all the components to each other.
- Memory modules (RAM) are inserted into slots on the motherboard. They provide short-term storage for data that the CPU is currently working on.
- Hard disk drives (HDDs) are used for long-term storage of data and are connected to the motherboard via a SATA cable.
- Optical disc drives are larger than HDDs and are typically connected to the motherboard with an IDE cable, though some newer drives use a SATA cable.
- Expansion cards are inserted into expansion slots on the motherboard. They provide custom functionality, such as improved graphics, audio, or network capabilities.
