Summary of computer basic knowledge points

Intellectual property maintenance knowledge of computer software (1) General comment: The government attaches great importance to the property rights maintenance of computer software. Since 1990, a series on the intellectual property maintenance of computer software has been successively introduced. List of policies and regulations. In 1998, the national cross-cutting legal system and law enforcement system for the maintenance of computer software have been basically formed.

Computer basicsKnowledge point induction Hardware knowledge The composition of the computer system includes hardware system and software system. The hardware system is divided into three typical structures: (1) single-bus structure (2), double-bus structure (3), large-scale system structure using channels. The CPU of the central processor includes a processor and a controller.

Computer basic knowledge point summary hardware knowledge The composition of the computer system includes hardware system and software system. The hardware system is divided into three typical structures: (1) single bus structure; (2), double bus structure; (3), large-scale system structure with channel. The CPU of the central processing unit contains the processor and controller.

Computer basic knowledge point summary The development, types and application fields of computers Computer (compuTer) Computer is an electronic device that can perform a large number of arithmetic and logical operations automatically and at high speed.

The basic knowledge of college computers is: computer definition: electronic computer, abbreviated as computer, is a kind of (electronic) machine that processes information, which can automatically, transmit and process information automatically, at high speed and accurately.

r Operation speed: MIPS million times per second, which refers to the number of addition instructions that can be executed per second. Storage capacity: memory, external memory. Word length: refers to the number of binary data bits that computer computing components can process at the same time; access cycle: refers to the time it takes for the CPU to access data from the internal memory.

College studentsComputer common sense that should be understood

1. Computer definition: Electronic computer, abbreviated as computer, is a kind of (electronic) machine that processes information, which can automatically, transmit and accurately store, transmit and process information.

2. The representation and operation of original code, inverse code, supplementary code, fixed number and floating point are also essential knowledge in programming, and almost every language needs to be involved. Nowadays, many languages are running on virtual machines. As long as you understand the composition principle of the computer and then look at which virtual machines, you will find that the concepts are all connected.

3. Do not hide inactive icons. After a period of use on the computer, the desktop operating system will automatically detect and hide inactive icons. Right-click in the blank space of the taskbar, and in the pop-up fastSelect "Properties" in the shortcut menu and cancel "Hide inactive icons" in the "Taskbar" tab.
