Computer (computer) commonly known as a computer, a high-speed computing for modern electronic calculator, can be numerical (1 + 1 = 2), and can be logically calculated (you hit me a punch, friendly or hostile ).
Binary: Binary calculation technique is widely used, the number of system types. 19th century Ireland logician George Boole thought process of logical propositions is transformed into the symbol "0", "1" is some kind of algebraic calculus, band 2 is every bit into the binary system. 0,1 is the basic operators. Because it uses only two numbers 0, 1 symbols, very simple and convenient, easy to implement electronically. .
(1) hardware system there are five major components: computing, controller, storage, input devices, output devices.
(2) operator: is responsible for arithmetic and logical operations. And controller together form the central processing unit (CPU).
(3) Controller: is responsible for sending and receiving instructions ...
(4) Memory: is used to store the program in progress, the program and the data to be processed the data immediately.
(5) The input device: the device is used for the input of e. Such as a keyboard, scanner or the like.
(6) an output device: the device is used for output. 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, T / O control chip, a keyboard and a control switch panel connectors, LEDs, connectors, expansion slots, and the insertion motherboards DC power connectors and other elements were electrically card.
Software program in order to complete a particular job and development.
Software is divided into system software and application software.
(1) System Software: System software refers to the control and coordination of computers and peripheral equipment to support application development and operation of the system, the computer system is responsible for managing a variety of independent hardware, so that they can coordinate their work. System software allows 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.
(2) application software, for example: iQIYI video, STORM, qqoffice etc.
The hardware is based on hardware, software needs to be activated by the control system hardware and lets refers to work with each other between the various hardware, system software on the basis of the user
