Study Notes
Introduction to Computer Hardware
- Computer hardware refers to the physical components of a computer system.
- These components work together to execute instructions and perform tasks.
- Key components include the central processing unit (CPU), memory (RAM), storage devices (HDD, SSD), input/output devices (keyboard, mouse, monitor), and motherboard.
Central Processing Unit (CPU)
- The CPU is the "brain" of the computer.
- It fetches, decodes, and executes instructions from programs.
- CPUs have multiple cores for parallel processing, increasing speed.
- Clock speed, measured in gigahertz (GHz), dictates the processing rate.
- CPU performance is crucial for overall system speed.
Memory (RAM)
- Random Access Memory (RAM) is essential for storing data and instructions.
- RAM is volatile, meaning data is lost when the computer is off.
- RAM speed and capacity directly impact system performance.
- More RAM allows for running multiple programs simultaneously.
Storage Devices
- Storage devices store data permanently.
- Hard Disk Drives (HDDs) use magnetic platters for storage.
- Solid State Drives (SSDs) use flash memory chips, faster and more resilient.
- Storage capacity is measured in gigabytes (GB) or terabytes (TB).
Input/Output Devices
- Input devices allow users to interact with the computer.
- Examples include keyboards, mice, scanners, microphones, and touchscreens.
- Output devices display or transmit the results of computer processing.
- Examples include monitors, printers, speakers, and projectors.
Motherboard
- The motherboard is the main circuit board.
- It connects and controls all other hardware components.
- It houses the CPU, RAM, and expansion slots for additional devices.
- Crucial for enabling communication between computer parts.
Graphics Processing Unit (GPU)
- GPUs are specialized processors for handling graphics and visual tasks.
- Particularly important for gaming, video editing, and graphic design.
- Modern GPUs often include dedicated memory to further enhance performance.
Expansion Cards
- Expansion cards are add-on circuits that add functionality to a computer.
- Examples include sound cards, video cards, network cards, and TV tuner cards.
- They often plug into slots on the motherboard.
Power Supply Unit (PSU)
- The PSU converts AC power to DC power to run computer components.
- Different PSU models cater to various needs and power consumption rates.
- Proper wattage is essential to accommodate all components and prevent damage.
Cooling Systems
- Cooling systems are vital for preventing computer overheating during operation.
- Fans, heatsinks, and liquid cooling systems are widely used to manage temperatures.
- Overheating can severely damage the hardware and affect its performance.
