Study Notes
Introduction to Computers
- A computer is an electronic device that processes input data and provides output.
- Composed of hardware (physical parts) and software (programs and data).
Hardware Components
- Hardware includes tangible elements like the motherboard, CPU, RAM, hard disk, etc.
Central Processing Unit (CPU)
- Acts as the brain of the computer, controlling operations and executing instructions.
- Performs arithmetic, logical, and I/O operations essential for software operation.
Graphics Processing Unit (GPU)
- Handles rendering of images, videos, and animations.
- Executes complex calculations to convert 3D models into 2D visuals for display.
Cooling Fan
- Essential for maintaining optimal CPU and GPU temperatures.
- Prevents overheating, which can lead to system crashes or freezes.
Storage Devices
- Storage devices are crucial for holding digital information.
Hard Disk Drive (HDD)
- Main data storage device, retaining music, videos, applications, etc.
- Utilizes magnetic disks for large capacity and quick data access.
Solid State Drive (SSD)
- Faster than HDDs, leveraging flash memory for data storage.
- More efficient but generally more costly compared to traditional HDDs.
Optical Drive
- Reads and writes data on optical discs such as CDs, DVDs, and Blu-rays.
Interconnects & Peripherals
- Interconnects facilitate the connection and data transfer between computer components.
- Peripherals are devices that interact with the computer, categorized as input (e.g., keyboard, mouse), output (e.g., printer), or storage (e.g., external hard drives).
Motherboard
- The primary circuit board that links all computer components, ensuring smooth integration and communication.
- Houses critical components like the CPU and RAM, which are vital for processing and temporary data storage.
Expansion Cards
- The motherboard includes slots for expansion cards to enhance functionality (e.g., graphics, sound, and network cards).
Power Supply Unit (PSU)
- A critical component providing electrical power to all other computer parts.
