Study Notes
The Personal Computer
- A computer is a device that allows interaction with hardware and performs calculations or functions.
- A computer consists of various components, including:
- Input devices (e.g., scanner, keyboard, mouse)
- Central Processing Unit (CPU)
- Memory (Random Access Memory)
- Expansion cards (e.g., video card)
- Power supply
- Optical disk drive (not always present)
- Storage devices (hard disk or SSD)
- Motherboard (connects components together)
- Monitor
- System software (e.g., operating system)
- Application software (e.g., internet browsers, document editors)
- Output devices (e.g., speakers, headphones)
- External devices (e.g., external hard drives, printers)
Electrical Safety
- Electrical devices have specific power requirements.
- Always ensure the correct AC adapter for a laptop, as swapping adapters can cause damage.
- Be cautious when working with high-voltage components, such as those found in printers and power supplies.
- Never open power supplies unless specifically trained to do so, as they can cause electrocution, fires, and fatalities.
- Electrostatic discharge (ESD) can occur when a surface with an electrical charge comes into contact with another differently charged surface.
