A personal computer is a programmable electronic system, which processes data and which is designed to have a single user at once. Over the years, computers have developed from all points of view and their components make no exception.
The central unit is the basic components of the system and it consist of the following. First of all, you have an asymmetrical and logical unit which does everything you want related to arithmetical and logical calculations. Then, there is the internal memory, also shortened in IM, an internal memory which stores the programs and the data which are in process. The, we have the command and control unit, which reigns over the entire ensemble.
There are also other kinds of components which make a personal computer and these components start with the peripheral ones. These establish the connection between your computer and the things around you. You have the input components, such as the keyboards and the mouse, then you have the output ones, such as the monitor and the scanner, then the storing ones, such as magnetic band units or CD-ROMs and last but not least, you have the communication components, such as the couple and the modem.
There are also constructive elements with a computer, the main ones being the system unit, the storage unit and the peripheral components of the connection components. When it comes to the central unit, this is actually a case and it involves everything that is in it, too. One of its main functions is the physical ones, this being the place where the internal components are mounted. The internal components refer to the main board, to the disk units, to the extension plates and so on. …
