The first thing to do in the process of understanding the fundamentals of computer is to be able to recognize a computer when you look at it. Computers are machines which run on electricity and offer all kinds of information to people and they are also uses used to store as well as give data to other machines also.

Personal computer was launched in 1985, is the best example of a computer which gives information. You can see four parts immediately, the system case which holds the components of the computer and there is a power cord connected to this case at one end and this is plugged into the power source at the other end. Then you have the input device, like the mouse and the keyboard, which is again attached to the system by wires. There is a production device, which is connected to the case with the help of a wire to the case, which is typically a monitor, and also has the screen. We can check out the different components in more detail, to get a better perceptive of the basics of computers.

With the help of input devices we are able to enter data into the computer, and it is the screen or the monitor which allows us to see the data which has been entered by way of the input devices. Almost one fifth of the basic computer which is placed in the system case is known as the primary storage device.  System disk is the other name for this storage device as it is the most often used storage device and has disk platters on which one writes the data and from that data can be read. It is common in information computers to have secondary storage devices, like the DVD or CD writers and readers, tape drives and floppy disk drives. These secondary storage devices let the user remove or insert tapes or disks. The opening of these gadgets can be seen in the frontage of the system case.  Nowadays tape drives and floppy disk drives are being replaced by DVD  and CD drives.
