Technology is the result of the application of scientific knowledge to create an object with practical benefit. More precisely, it is defined as the application of scientific knowledge for practical purposes, particularly in industry.

Technology does not extend much in a wide field and deals with the knowledge and use of tools and techniques, and how it affects a species’ ability to control and adapt to its environment. One of the most important devices in technology is the PC.

The computer is a machine made mainly from digital electronic circuits and secondarily from electrical and mechanical systems, and is designed to process Information. The computer is an automated, electronic, digital reprogrammable generic system that can process data based on a set of predefined instructions or commands, which collectively are called a programme.

Every computer system, as large or as small, is made up of the hardware and the software. The basic components of the computer hardware are the central processing unit, the central memory, the input / output units, the internal (or external) read and write units such as hard disk, DVD, SSD and peripheral devices such as printer, scanner, modem, etc.
