What is Computer: PC commonly known, is calculated for a high-speed modern electronic calculators, numerical calculations may be performed, but also calculation logic, and memory function, the program is able to run in automatic, high mass processed modern intelligent electronic device data.

 

Second Binary:

 

Binary number system is a kind of computing technology widely used in the 19th century Irish logician George Boole thought process of logical propositions is transformed into the symbol "0", "1" is some kind of algebraic calculus, nearly every system is, carry the 2 binary system, 0 is the basic operators, because it uses 0,1, two numeric symbols used in electronics very simple and convenient manner.

 

Hardware system

 

1. There are five major components: computing, controller, memory, input devices, output devices.

 

2. The operator: is responsible for arithmetic and logical operations, and controller together form a central processor.

 

3. The controller is responsible for sending and receiving commands.

 

4. The memory is used to store the program in progress to be performed and data of the program data has just finished processing.

 

The input device is used for input devices, such as keyboards, scanners.

 

6. The output device is used for the output device such as a display, speakers and the like.

 

Motherboard: motherboard generally rectangular circuit board above the main circuit composed of a computer system is installed, generally BTOS chip, I / O control chip, a keyboard and control panel switch interface lamp connectors card expansion slot board and DC power supply, connectors and other software.

 

Software program in order to complete a particular job and development.

 

Software can be divided into: 1 System Software: System software refers to the control and coordination of computers and peripheral equipment, application software development and operational support systems, is a collection of programs without user intervention, the main function is to monitor and maintain computer scheduling system responsible for managing a variety of independent computer systems hardware so that they can coordinate the operation of the system software, so that the computer users and other software to the computer as a whole, without the need to take into account the underlying hardware is how each works. For example: Windows xp, Windows7, Windows 8, Windows10, Android, ros, unix, linux.

 

2. Application Software Type: iQIYI video, storm tones, qq

 

The hardware is based on the hardware, software control systems need to be where the hardware and allow mutual coordination between the various hardware, system software on the basis of a user, the user's control system software, and install the system software on the basis of the corresponding software to complete the work required by the user, so that the bottom is the hardware, the hardware layer of system software, system software layer is the application software, which is the top user.
