In the context of a computer, it refers to the role of the power supply unit in converting AC from the wall outlet into DC that the computer components can use. | | Power Supply Unit | The power supply unit in a computer is responsible for converting AC from the wall outlet into DC. It also regulates the voltages to ensure they are at the correct levels for the specific computer components. | | Motherboard | The main circuit board in a computer where major components are installed or plugged into. It has places for the processor, cache, and memory to plug into. | | Chipset | Allows the storage and input devices to interface with the processor, memory, and cache. The chipset determines which processor can be used in the PC, how much cache and memory can be loaded, etc. | | Controllers | Individual specific data managers that interface with specific devices, such as a floppy controller, keyboard controller, etc. | | Buses | Shared channels or interfaces going to or from the processor. They can vary in speed and capacity. | | BIOS (Basic Input/Output System) | Firmware instructions burned into the ROM that interface between the various hardware components on and plugged into the motherboard and the operating system. | | CPU (Central Processing Unit) | Interprets the instructions it finds in memory (programs) and responds to and modifies that information, directing the other components in response. | | Why Computers Use DC | Computers use DC because it provides a constant and stable voltage, it's safer, many electronic components are designed to work with DC, it allows for energy storage, and it's necessary for signal processing. | Please note that Markdown tables may not render correctly in all environments.
