Personal Computer Hardware

The term Personal Computer Hardware refers to all tangible parts of a PC, the components are: electric, electronic, electromechanical and mechanical. These cables, cabinets or boxes, peripherals of all kinds and any other physical element involved; software is intangible and is called software. The history of Personal Computer Hardware can be classified into four generations, each characterized by a change of technological importance. A first delineation could be made between basic hardware, the minimum required for normal operation and complementary which performs specific functions. A computer system consists of a central processing unit (CPU / CPU) responsible for processing the data, one or more peripheral input, allowing the entry of information and one or more output devices, which enables to give output (usually as visual or auditory ) to the data processed.

 

Classification of Personal Computer Hardware

 

One way to classify the Personal Computer Hardware is to divide in two categories: first, the core, which covers all essential components required to provide the minimum functionality to a computer and on the other hand, the complimentary hardware which, as the name suggests, is used to perform specific functions beyond the basics, not strictly necessary for the operation of the computer.

The central processing unit (CPU), RAM, output and data storage constitutes the basic hardware.
