What is Computer Hardware?

Computer hardware refers to the physical components of a computer system
that are essential for processing, storage, and functionality. These
include internal parts like the processor, memory, and storage, as well
as external peripherals such as monitors, keyboards, and mice.

Benefits of Quality Computer Hardware

• Enhanced Performance: High-quality hardware ensures
  smooth and efficient operation, reducing lag and downtime.
• Longevity: Durable components withstand intensive
  usage and maintain performance over time.
• Upgradability: Quality hardware is often modular and
  compatible with upgrades, extending the system's lifespan.
• Energy Efficiency: Advanced hardware reduces power
  consumption while maintaining performance.
• Cost-Effectiveness: Reliable hardware minimizes the
  need for frequent repairs and replacements.

Categories of Computer Hardware

Internal Components

• Processor (CPU): The brain of the computer that
  performs calculations and executes instructions (e.g., Intel Core i7,
  AMD Ryzen 9).
• Motherboard: The central circuit board connecting all
  components.
• RAM (Memory): Temporary storage for active processes
  (e.g., 8GB, 16GB DDR4).
• Storage Devices:
  • HDD: Large capacity but slower (e.g., 1TB).
  • SSD: Faster storage (e.g., 512GB NVMe SSD).
• Graphics Card (GPU): Dedicated or integrated for
  rendering images and video (e.g., NVIDIA RTX 3080).
• Power Supply Unit (PSU): Converts electricity for
  powering components (e.g., 650W PSU).
• Cooling System: Includes fans, heat sinks, or liquid
  cooling systems.

External Components (Peripherals)

• Monitor: Displays output (e.g., 24” 4K UHD monitor).
• Keyboard: Input device with various layouts (e.g.,
  mechanical keyboard).
• Mouse: Pointing device (e.g., optical mouse).
• Speakers/Headphones: For audio output.
• Printer/Scanner: For document handling.
