## Components of a Computer
|
||||
|
||||
1. **CPU**: Central Processing Unit - The "brain" of the computer that performs calculations and logic operations.
|
||||
2. **RAM**: Random Access Memory - Temporary data storage that is faster to read and write compared to hard drives.
|
||||
3. **Hard Drive**: Long-term data storage, can be HDD or SSD.
|
||||
4. **Motherboard**: The main circuit board connecting all components.
|
||||
5. **Power Supply**: Converts electrical power to a format suitable for the computer.
|
||||
6. **GPU**: Graphics Processing Unit - Handles rendering images and videos.
|
||||
7. **Input Devices**: Devices like keyboards, mice, and scanners for user input.
|
||||
8. **Output Devices**: Devices like monitors, printers, and speakers for displaying output.
|
||||
9. **Cooling System**: Fans or liquid cooling to maintain optimal temperature.
|
||||
10. **Case**: Houses and protects the components.
|
||||
|
||||
## Input and Output Devices
|
||||
|
||||
### Input Devices
|
||||
Input devices provide data and control signals to a computer. Examples include keyboards, mice, scanners, cameras, joysticks, and microphones.
|
||||
|
||||
#### Types of Input Devices
|
||||
- **Keyboards**: Text input
|
||||
- **Mouse/Touchpad/Trackpoint**: Pointer navigation
|
||||
- **Scanners**: Image input
|
||||
- **Webcam/Cameras**: Video input
|
||||
- **Microphone**: Audio input
|
||||
- **Joystick**: Game control
|
||||
|
||||
### Output Devices
|
||||
Output devices display or output data from a computer. Examples include monitors, printers, and speakers.
|
||||
|
||||
#### Types of Output Devices
|
||||
- **Monitor**: Visual display
|
||||
- **Speakers/Headphones**: Audio output
|
||||
- **Printers**: Printed output
|
||||
|
||||
## Storage
|
||||
|
||||
### Units of Storage and Speed
|
||||
- Byte, Kilobyte, Megabyte, Gigabyte, Terabyte
|
||||
- RPM, Read/Write Speed
|
||||
|
||||
### Types of Storage
|
||||
- **Magnetic Storage**: HDD
|
||||
- **Optical**: CD, DVD
|
||||
- **Solid State**: SSD
|
||||
|
||||
## Machine Language
|
||||
- **Binary**: The basic language of computers, consisting of 0s and 1s.
|
||||
|
||||
## Networking
|
||||
|
||||
### Explain Protocols
|
||||
- Rules governing data transfer
|
||||
|
||||
#### Types of Protocols
|
||||
- **TCP**: Reliable data transfer
|
||||
- **UDP**: Faster but less reliable
|
||||
- **MAC Address**: Hardware identification
|
||||
- **IP/DNS**: Internet addressing
|
||||
- **Network Ports**: Data pathways
|
||||
- **Subnetting**: Network segmentation
|
||||
- **Firewall Usage**: Security measure
|
||||
- **Other Protocols**: HTTP, FTP, SSH, TELNET
|
||||
- **OSI Model**: 7-layer model for networking
|
||||
- **VPNs**: Virtual Private Networks for secure communication
|
||||
|
||||
## Operating System
|
||||
- **BIOS**: Basic Input/Output System, the firmware for initializing hardware.
|
||||
- **File System**: Manages how files are stored and retrieved.
|
||||
- **Kernel**: Core part of OS, manages system resources.
|
||||
- **Drivers**: Software to interface with hardware.
|
||||
- **Examples of Operating Systems**: Windows, macOS, Linux
|
||||
