The data it processes is gathered via the system bus, from the main memory. The CPU then sends back the results to main memory via the system bus. The CPU also controls and times the operations of the other key components. CPU's use in their operation: Fetch, decode, execute, and writeback. BIOS - The BIOS is a built-in software that decides what a computer can do without having access to a hard drive or CD/DVD. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of other miscellaneous functions. Motherboard - The motherboard is a printed circuit board (PCB) that houses and controls the components that are in charge of processing data. A motherboard provides the electrical circuit connections, these circuits are used by other components of the system to communicate. ...read more.

Fortunately my antivirus does not need updating as my current virus signature database is up to date . This is what happens when it's not up to date, after a speedy download it will take me to the previous page and let me know if it's up to date. Hardware maintenance. To demonstrate hardware maintenance I'm going to find and use a printer that is connected to a separate computer on my network. ...read more.
