Understanding How A Computer Works

How Does A Computer Work

The term “processor” refers to a unit that executes the instructions that are transmitted from the computer software through an interface to an input device such as a keyboard or mouse. The word “registers” has a broader meaning that includes storage areas for temporary data and function keys that control the operation of the CPU. Instructions are executed by getting the result signal from an input device and passing it through the CPU. The computer then displays the output, which usually results in some form of on screen display.

Understanding All About Computer

A computer works because of its different components, which combine together in order to execute instructions given by the software or hardware. At boot time, the operating system loads a chip called the boot ROM, from a removable device like a floppy disk or CD. Then the boot ROM is accessed from the BIOS, or the Central processing unit, also installed in the PC, which in turn bootstraps the PC from non-bootable media. The BIOS chips either allow the computer to perform a certain operation or provide a security mechanism against intruders. Whatever the case, the BIOS is crucial to the operation of the computer and normally has to be programmed by the manufacturers.

How Does A Computer Work – Computer Technicians without a BIOS? In a nutshell, a PC gets its power supply through the mother board, which plugs into an external power supply, and from there goes to the CPU. From the CPU, the output device, which could be a joystick, game pad, printer, or an external disk drive, gives the user’s commands to the software, which in this case is a specialized operating system. In short, from the CPU up to the output device, all has to be designed and built for the user’s instruction. And so, even if one wants to change the settings of their PC, they would need to know how the motherboard and its various components work.
