A PCB (Printed Circuit Board) is a substrate used to support and electrically connect electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate.

A device that provides electrical power to an electrical load by converting electric current from a source to the correct voltage, current, and frequency.

The iterative process of creating a preliminary model of a product for testing and validation.

A resistor used to ensure a known voltage level at a high-impedance input pin.

PWM (Pulse Width Modulation) is a technique for modulating the width of the pulses in a pulse signal to control power delivery to electrical devices.

PC assembly is the process of assembling individual hardware components and connecting them to form a fully operational personal computer.

A set of specialized tools and equipment for assembling and disassembling personal computers.

Modification of a personal computer case for functional or aesthetic improvements.

A PCIe card is an expansion card that connects to a computer's motherboard via a PCI Express (Peripheral Component Interconnect Express) slot, providing additional ports and functionality.

A version of the Peripheral Component Interconnect Express standard defining data transfer rates, lane width, and link speed.

PCIe lanes are data pathways that enable communication between PCIe devices and the motherboard.

A PSU, or Power Supply Unit, is an internal hardware component that converts AC to DC power for computer components.
