Study Notes
Types of PC Systems
- Full-Size Tower: A computer case that is vertically oriented, typically located on the floor, providing room for expansion to accommodate additional components such as disk drives, adapter cards, and more.
- Compact Tower: A smaller version of the full-size tower, commonly found in corporate environments, also known as mini-tower or small form factor (SFF) model, located on the user desk or floor, providing limited room for expansion.
All-in-One PC Systems
- A computer system where all components are integrated into the display, often featuring touch-screen input, built-in microphone and speakers, with little to no expansion capabilities.
- Requires an external keyboard, mouse, and power supply.
Computer Case Design
- Cases contain fans to move air through the case, absorbing heat from warm components and exiting the case to prevent overheating.
- Designed to protect against static electricity damage by grounding internal components via attachment to the case.
Power Supplies
- Computers require direct current (DC) power, while wall outlets provide alternating current (AC) power.
- Power supplies convert AC power into lower voltage DC power for computer components.
- Computers can tolerate slight fluctuations in power, but a stable power supply is essential.
