Computers and Its Parts

If you use a desktop computer, you may already know that there isn't any particular part called the computer. A computer is in fact a system of many parts working together. Starting from the main system unit, the system unit is the core of a processor system. Usually it's a rectangular box placed on or under your desk. The most important of this mechanism is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another part is random access memory (RAM), which momentarily stores information that the CPU uses while the computer is on. Almost each part of the computer connects to the system unit using cables.

Let’s talk about storage space and what it does for us. Your computer has one or more disk drives plans that store information on a metal or plastic disc. The disks conserve the information even when your computer is turned off. Computer’s hard disk drive stores information on a hard disk, a rigid plate or stack of plate with a magnetic facade. Because hard disks can hold massive amounts of information, they typically serve as your computer's primary means of storage space, holding almost all of your programs and files. But there is one more type of storage option in use computers, which was used as the main means to make data portable, known as the floppy disk. Floppy disk drives store information on floppy disks, also called floppies or diskettes. It’s known that floppy disks can store only a small amount of data.

For this motive, floppy disk drives are less accepted than they used to be, though some computers still include them. Now you think why are these small diskettes called floppy disks? The disk inside is made of a thin, flexible vinyl material. The rest of the processor features, how you input data into it. A mouse is a small device used to point to and select items on your screen. Although mice come in many shapes, the typical mouse does look a bit like a genuine mouse. It's small, oblong, and connected to the system unit by a long wire that resembles a tail. That is why it is called a mouse. A mouse regularly has two buttons: a primary button (usually the left button) and a minor button. Many mice also have a wheel between the two buttons, which allows you to scroll easily through screens of information. The other type of input data is the keyboard.
