Today, I would like to talk to you about what data is, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

Data is the result of facts or observation, the logical induction of objective things, and the raw material used to represent objective things. Data can be continuous values, such as sound, image, called analog data; it can also be discrete, such as symbols, text, called digital data. In a computer system, data is represented in the form of a binary information unit 0Pol 1.

Data (data) refers to the symbols that record and identify objective events. It is the physical symbols or combinations of these physical symbols that record the nature, state and interrelationship of objective things. It is a recognizable, abstract symbol.

It not only refers to numbers in a narrow sense, but also can be a combination of words, letters, digital symbols, graphics, images, video, audio and so on, but also an abstract representation of the attributes, quantity, location and interrelationship of objective things. For example, "0, 1, 2.", "overcast, rain, drop, temperature", "student records, cargo transportation" and so on are all data. After processing, the data becomes information.

In computer science, data refers to the general name of all the symbols that can be input into the computer and processed by the computer program, which is used to input the electronic computer for processing, and a general term for numbers, letters, symbols and analog quantities that have a certain meaning. Computers store and process a wide range of objects, and the data representing these objects becomes more and more complex.

Semantics of data

The form of expression of the data can not fully express its content and needs to be interpreted. The data and the interpretation of the data are inseparable.

For example, 93 is a data, which can be a classmate's grade in a course, a person's weight, or the number of students in the computer science department of the class of 2013.

The interpretation of data refers to the explanation of the meaning of the data, the meaning of the data is called the semantics of the data, and the data and its semantics are inseparable.

After reading the above, do you have any further understanding of what the data is? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
