The Five Components of the PC are: 1. System Unit - The main part of a personal computer. The system unit includes the chassis, microprocessor, main memory, bus, and ports, but does not include the keyboard or monitor, or any peripheral devices. A system unit is sometimes called a box or main unit. 2. Monitor - A monitor or display (sometimes called a visual display unit) is an electronic visual display for computers. The monitor comprises the display device, circuitry, and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube about as deep as the screen size. 3. Keyboard - a keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers. 4. Mouse - a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations. 5. Cables – Computer Cables are a group of different types of cables or cords that attach to a computer for the purpose of supplying electricity to the power supply or connecting devices that supply input or output for the computer.
The Components of the System Unit are: 1. Motherboard (or Main Board) - a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system,
