2. Types of Hardware Components
Computer hardware can be broadly classified into three categories:
- Internal Components: Components that are housed inside the computer case.
- External Components: Components that connect externally to enhance functionality.
- Peripheral Devices: Additional devices that expand user interaction with the computer.
Each type serves unique roles but works in unison to provide a seamless computing experience.
3. Internal Hardware Components
Internal components are the core of any computer, handling processing, memory, and storage. Let’s explore the main internal components:
a) Central Processing Unit (CPU)
- Description: Often called the brain of the computer, the CPU executes instructions and performs calculations.
- Key Features: Measured in GHz, core count, and cache size.
b) Memory (RAM)
- Description: Random Access Memory (RAM) temporarily stores active data for quick access.
- Key Features: Speed and capacity measured in GB, crucial for multitasking.
c) Storage Devices (HDD and SSD)
- Hard Disk Drive (HDD): Mechanical storage with higher capacity but slower speed.
- Solid State Drive (SSD): Fast, electronic storage ideal for operating systems and frequently accessed files.
d) Graphics Processing Unit (GPU)
- Description: Handles rendering of images and graphics, essential for gaming and graphic design.
- Key Features: Dedicated or integrated graphics, crucial for visual-intensive applications.
e) Power Supply Unit (PSU)
- Description: Converts electricity into usable power for the computer’s components.
- Key Features: Wattage and efficiency ratings, powering all internal parts.
