What do words mean in computer literacy?

A mirror image is a form of document that can be used to make many documents into a single image file. For example, your system,There were a lot of files.,Make a mirror image on a file.,And ghost and other programs are placed in a disk with ghost and other software after opening,And then restored into many files.,In short, use the mirror image to install the system for you is to copy the meaning of the existing system as it is.,Of course, the anti-virus software inside is also copied in the same way.,As for the mirror image** and the mirror image file seems to have nothing to do with it.。

There is also a common sense that if there are more people who use the genuine version, it will become piracy, and the genuine users each have a genuine serial number, which is mainly used for upgrading and patching, so.

The mirror image and the genuine version cannot be equated, the main thing is to have a serial number.

Of course, it is rumored that the genuine mirror image will be a little more stable than the pirated version, it is rumored that it is only. Of course, I also tell a few words: mirroring** means that the server has the same thing available on another host** It is recommended to use it to speed up ** The same is true for mirror browsing Multiple hosts have the same web page Choose the mirror browsing closest to you can speed up browsing These you can see for yourself the relevant information It's very simple!

1.Keyboard: a command rerouting and data input device used to operate the equipment, and also refers to a set of function keys arranged to operate a machine or equipment through the system;

2.Main unit: The main part of the computer except for the input and transmission equipment. It is also a control cabinet used to place the motherboard and other major components;

3.Mouse: An input device for the computer, and also an indicator for the computer's display system to locate the ordinate axis, named because it resembles a mouse;

4.Hard disk: one of the main storage media of a computer, consisting of one or more aluminum or glass discs;

5.Memory: One of the most important parts of a computer, it is the bridge to communicate with the processor. The running of all programs in the computer is carried out in memory, so the performance of the memory has a very large impact on the computer;

6.**Processor: It is a very large-scale integrated circuit, which is the computing core and control core of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software;

7.Graphics card core: the full name of display interface card, also known as display adapter, is one of the most basic configuration and important accessories of a computer.

Computer term attributes are descriptive properties or characteristics of an entity, which have three properties: data type, domain, and difference default value. Attributes are also often used to describe the characteristics of a control. For the name of the button control, the text displayed, the background color, the background, and so on.

The properties that most controls have are called common properties: name, title, background color, foreground color, and so on. Information used for files that indicates whether the file is read-only, hidden, prepared for archive (backup), system file, compressed, or encrypted, and whether the contents of the file should be indexed to speed up file searches.

In Active Directory, it refers to the characteristics of an object and the type of information that an object can contain. For each object class, the schema defines what attributes a category instance must have and what other attributes that category instance may have. An attribute is an arbitrary feature of a programming language structure.

Attributes vary greatly in terms of the information they contain and the complexity they contain, especially when they can determine the time it takes for the translation process to be performed. Typical examples of properties are: the data type of a variable, the value of an expression, the location of the variable in memory, the goal of the program, and the number of significant digits of the number.

In programming, properties can be determined before complex processing, or even the construction of a compiling program. For example, the number of significant digits of a number can be determined (or at least given a minimum value) based on the definition of the language. Attributes can also be determined during program execution, such as the value of a (non-number) expression, or the position of a dynamically assigned digital data structure.

Different attribute variations, and even the same attribute in different languages, may have completely different concatenation times. The properties of the syndicate before execution are called static, and the properties of the syndicate are dynamic only during execution. rIn object-oriented programming, a property is a value corresponding to a variable or a constant, such as:

this->aaa, then the property of $this is aaa
