Questions and Answers
What is the main function of the Central Processing Unit (CPU) in a computer?
The CPU acts as the brain of the computer, executing instructions and processing data.
Explain the difference between a Hard Disk Drive (HDD) and a Solid State Drive (SSD).
HDDs use magnetic storage with larger capacity and slower speeds, while SSDs use flash storage, offering faster access times but at a higher cost.
What role does the motherboard play in a computer system?
The motherboard houses essential components like the CPU and RAM and connects different parts of the computer.
How does Random Access Memory (RAM) impact a computer's performance?

Study Notes
Computer Hardware
-
Definition: Physical components of a computer system that perform specific functions.
-
Main Components:
-
Central Processing Unit (CPU):
- The brain of the computer that executes instructions.
- Measured in gigahertz (GHz); higher GHz indicates faster performance.
-
Motherboard:
- Main circuit board housing the CPU, RAM, and other components.
- Connects different parts of the computer.
-
Random Access Memory (RAM):
- Temporary storage used by the CPU to store data that is actively being used.
- More RAM allows for better multitasking.
-
Storage Devices:
- Hard Disk Drive (HDD): Magnetic storage with larger capacity and slower speed.
- Solid State Drive (SSD): Flash storage, faster access times but typically more expensive.
-
Power Supply Unit (PSU):
- Converts electrical power from an outlet to usable power for computer components.
-
Graphics Processing Unit (GPU):
- Specialized processor for rendering graphics and visual effects.
- Critical for gaming and graphic design tasks.
-
Cooling Systems:
- Essential for maintaining optimal operating temperatures.
- Includes fans and heat sinks to dissipate heat generated by components.
-
Central Processing Unit (CPU):
-
Peripheral Devices:
-
Input Devices:
- Devices that allow users to input data, e.g., keyboard, mouse, scanner.
-
Output Devices:
- Devices that output data, e.g., monitors, printers, speakers.
-
Storage Devices:
- External hard drives, USB flash drives, and optical drives (CD/DVD).
-
Input Devices:
-
Types of Computer Hardware:
- Desktops: Fixed computers typically consisting of separate components.
- Laptops: Portable computers with integrated components.
- Servers: Powerful systems designed to manage network resources and data storage.
- Embedded Systems: Computers integrated into other devices, e.g., appliances, vehicles.
-
Expansion Slots and Ports:
