If you have ever wondered how computers work, here is a chance for you to understand the basics. While the technical aspects of what makes computers work could be difficult for a non-professional to understand, the mechanical aspects of it can give you a clear idea of what and how things happen inside a processor.
Computers work thanks to a series of hardware devices that are closely interconnected. The basic components of a computer are the motherboard, or tower; the monitor; and the keyboard. The mouse may or may not be essential to the functioning of a computer, depending on the type and model.
Most of the essential things that make computers work are inside the tower, away from your eyes. The central processing unit (CPU), located inside the computer tower, is the central stop for all the processes the computer goes through. As a command is sent, such as “open a program” or “turn the monitor on,” the CPU interprets this order and then acts accordingly.
Once the computer is turned on, or booted up, the CPU goes on to activate certain sections so that it can then give you access to programs and processes. Computers work based on the CPU granting access to users, so malfunctioning of the booting up process would mean that the computer could not be used, even if everything inside is working properly.
The first step to make computers work is to run the BIOS software, which checks basic data such as hard memory, RAM, type of video card installed, and CD-ROM/Floppy drives. BIOS also checks for booting up errors and offers to fix them if necessary. BIOS is also known as ROM BIOS or Read-Only Memory Basic Input/Output System.
Input/output (I/O) is the name given to the processes or components needed to interact with the CPU and make computers work. These include the monitor and keyboard, but also CD-ROMs, Floppy disks, and removable flash memory cards. Input/output processes allow you to order the computer to do something, making the essential for interaction and use.
