The most basic unit - system. In fact, this is the computer for at least its most important component. In the chassis housing the main unit admission, transfer, processing and storage of disk imaging. Specifically connected to it all, without exception, device companies, for example, monitor, keyboard, printer.
All the major components of a computer, which can be replaced, removed, or added, or are inside the system unit, or connect to it from outside. Thus, all the strength and power of a computer is located in the system unit.
System unit
System unit (or the name of another sistemnik housing) - is housing which contains their different components of multi-functional computer. Outer shell, namely housing - traditionally made by steel, aluminum and plastic, less likely to use plexiglass or wood.
On the body, usually a lot of holes, and it is absolutely no coincidence. These openings are provided for ventilation, which is essential for the smooth running computer.
Power_Reset
Power and Reset buttons
Pay attention to the two keys that are on the outside of the chassis: a computer power button POWER (big fine noticeable) and traditionally close to her small restarting the computer RESET.
RESET button, though small, but udalenkaya. If a computer "frozen", did not respond to all kinds of your team, you can click on this button to restart the computer. However, such a miracle RESET button on some of the blocks and it just is not there on a laptop.
Tower system unit
System units vary in different form factor (size), and according to their appearance. There are the following types of cases:
desktop
Desktop system unit
horizontal (type Decktop - desk) and vertical (Tower-type tower).
First came the desktop system unit types. The screens were then relatively small and they were put straight on the desktop. Then it turned out that almost all the user does not want to clutter up your workspace and the first plan began to come out of the tower. They subsequently took the position of favorite.
The towers are divided into 4 subtypes, which differ in height. In order of increasing it: Micro (Micro Tower), Mini (Mini Tower), MIDI (Midi Tower - average) and total (Big Tower).
Practice shows that in most of the cases are acquired Midi Tower Case and Big Tower. This is due to the fact that energy consumption and heat generated by the cutting-edge components, require a corresponding size of the case and its internal organization.
System unit
Decktop with LCD
Desktops or preserved on very old computers, or sometimes you can meet on the latest models. An old CRT (cathode ray tube) with wide screen when placed on the desktop it could damage their own weight. The emergence of LCD (liquid crystal), the weight of which is substantially less than the CRT, gave a second life to a desktop package. Currently, they are used when you want to place a computer on the desk while poekonomit space. Such option resort in some schools and offices.
If you talk about saving desktop space when placed on it the entire company and to have a great byutzhet, it is impossible not to recall more of the same system case, which in the future will probably take the position of favorite.
Touchscreen candybar
Candy bar - is a type of computer that will fit in a single package and monitor the system unit. In this case, go into oblivion many wires, fan noise. There is a single touch screen (touch-sensitive, for example, finger). In this case, it seems that the keyboard and mouse without the need to. But the keyboard while still should not throw, or how you print the text?
