Identifying Hardware Components and Their Functions
Start by naming the critical internal parts: the motherboard, central processing unit (CPU), random‑access memory (RAM), storage drives, and power supply unit (PSU). These provide the foundation for understanding system architecture.
The motherboard is the primary circuit board that connects all internal parts and enables communication among them. :contentReference[oaicite:0]{index=0}
The CPU executes instructions, performs calculations, and coordinates data flow; it acts as the system’s main computational engine. :contentReference[oaicite:1]{index=1}
RAM temporarily stores data that the CPU uses for active tasks; it loses its content when power is off, making it volatile memory. :contentReference[oaicite:2]{index=2}
Storage devices include HDDs or SSDs, where data is retained long term. Their interfaces, such as SATA or NVMe, affect speed and capacity. :contentReference[oaicite:3]{index=3}
The PSU converts AC power from a wall outlet into the DC voltages needed by internal components. Power ratings (e.g., wattage) must match the system’s requirements. :contentReference[oaicite:4]{index=4}
