This lesson introduces the main hardware components of a computer and their basic functions. You will learn to recognize fundamental parts such as the motherboard, CPU, RAM, hard drives (HDD or SSD), power supply unit (PSU), and graphics card.

Every computer is made up of different components that work together to ensure everything operates smoothly. The motherboard is the main component that connects all the others, acting as the backbone of the system. The CPU (Central Processing Unit) is often referred to as the “brain” of the computer because it processes all instructions and commands. The RAM (Random Access Memory) is a temporary storage used to speed up data access during operation. The power supply unit provides energy to the entire system, while hard drives (HDD or SSD) store data persistently, even when the computer is off. Graphics cards manage the visual output, making them essential for rendering graphics-intensive applications, such as video games or design software.

Understanding these components is crucial for being able to disassemble, repair, and ultimately reuse parts effectively.
