The hardware Of the computer are the physical parts, that is, those that we can see and touch, of a computer system. Without him software, which comprises the intelligent part of the computer (that is, the programs and applications), the hardware would be of no use.

The hardware It is normally made up of a process control unit or CPU, on a motherboard, which contains the microprocessor (a fundamental element of every computer) and the hard disk, memories, video cards and power supply, among others. Also the monitor and keyboard, which are called peripheral components.

These parts are always electrical, electronic, electromechanical or mechanical elements that perform specific functions for the computer to function properly.

Hardware over time

Before microprocessors existed, hardware electronics were based on integrated circuits, and going further in time, in transistors or vacuum tubes.

Hardware elements are usually divided into four types:

• Data input devices
• Data output devices
• Data storage devices
• Information processing

For a long time hardware was presented to the public in the form of modular desktops, that is, with standard modules that are easily removed or added.

Then models began to appear all in one, that is, all in one, which take up much less space. They also became very popular type laptops notebookor even more girls, the netbooks, which are almost as light and small as a notebook.

Hardware Components

The keyboard it is a hardware component, used to input data into the computer. The CPU processes the information that enters the computer. The monitor and the speakers allow information output.

So that the hardware function properly, all devices must be connected. Of course, all software must also be properly prepared.

It is much more common for computer equipment to malfunction due to flaws in the software that in the hardware. However, elements such as the power supply or the fan may deteriorate and require replacement.
