1. Understanding the Basics of Computer Hardware

Computer hardware consists of physical components that make up a computer system. These include:

• Central Processing Unit (CPU): The "brain" of the computer that processes instructions.

• Motherboard: The main circuit board that connects all components.

• Memory (RAM): Temporary storage that helps with multitasking and processing speed.

• Storage Devices (HDD & SSD): Hard drives store data permanently, while SSDs offer faster speeds.

• Power Supply Unit (PSU): Converts electricity into usable power for the computer.

• Graphics Processing Unit (GPU): Handles graphics rendering, crucial for gaming and video editing.

• Cooling System: Fans and liquid coolers prevent overheating.

• Input/Output Devices: Keyboards, mice, monitors, and other peripherals.
