What Happens Inside a Computer?

Computers have become a very important part of our daily lives. Either at home, either at the office, either for gaming, watching movies, checking mails and so on. But probably a few of us ask themselves what it's inside a computer and how it works. In a few words we'll help you figure it out.

You need to have in sight 3 major factors when you want to know how a computer works: the hardware part, the operating system part and the software part.

As any other machine which has to work with data's (send, receive and process), a computer has a motherboard (it's also called main board, system board or on the Apple computers, logic board). This is a primal board which has all the crucial components to provide the information further. Another main component is the CPU (central processing unit). This CPU coordinates the activity of the entire system. These two components are the most important hardware devices of a PC. Of course there are and other system devices like a Random Access Memory (RAM), a Hard Disk, a compact disk read-only memory (CD-ROM), a floppy disk, a graphic card, a sound card, a network adapter and the periphery devises like keyboard, mouse, printer and others.

When we turn the power on, the system starts to boot. The first things that you see, are the basic input output systems (BIOS), which starts to communicate with CPU by making a quick test of all the hardware components and then send the information to further. After this, the CPU takes the control, having two tasks: manage the flow of data and assure the right deployment of the mathematical and logical operations. Inside the CPU the amount of interactions between flown or released electrons, tiny electronic components allows to be processed billions of basic unit information every second.
