Computer Hardware Basics
Computer hardware basics refer to the fundamental physical components that make up a computer system. These include the central processing unit (CPU), memory (RAM), storage devices (such as hard drives or SSDs), motherboard, power supply, and input/output devices like keyboards, mice, and monitors. Understanding these basic parts is essential for assembling, maintaining, or troubleshooting computers, as each component plays a specific role in processing data and ensuring the system operates efficiently.

❓ Frequently Asked Questions
What is the CPU and what does it do?
The CPU is the computer's brain that executes instructions, performs calculations, and coordinates data flow.
What is RAM and why is it important?
RAM is temporary, fast memory used by active programs; more RAM lets you run more tasks at once, and data is lost when power is off.
What is the difference between hard disk drives and solid state drives?
Hard disk drives use spinning magnetic disks; solid state drives use flash memory with no moving parts. SSDs are faster and more durable, while HDDs are cheaper per gigabyte.
What does the motherboard do in a computer system?
The motherboard is the main circuit board that connects the CPU, memory, storage, power, and peripherals, allowing components to communicate.
What is the role of the power supply?
The power supply converts mains AC to the DC voltages used by all components and provides power through connectors with a specified wattage.
