ThreeStagesoftheDevelopmentofComputer:MachineLanguage,AssemblyLanguageandHigh-level

(2019-03-22 10:40:52)

In this increasingly development information age, technology is changing with each passing day, and the development of computers and Internet networks has become an important part of people's daily lives. Learning one or two computer programming languages is as hot as learning English. With the continuous development of artificial intelligence AI and cloud computing, Python language and Scala language have become the hottest programming languages in these two fields, and can predict the future. People who learn computer programming languages will become a new normalcy as well as learning English, and become a stable normal. Now briefly explain the development of computer programming languages.

The brief introduction of programming language

Computer language, or Programming Language, refers to a language in which people interact with computers. Just as we learn foreign languages, it is just a formal tool. It is our thought to communicate with computers. Our own thoughts are given to him in a computer-readable language, and a procedure is formed. And a series of problems in realizing our thinking is to send instructions to the computer. For both sides of the communication, the format of the instructions, the composition of characters, digital data, grammar and other standards are very important, and what we learn is this series of standards, in order to give their own ideas to the computer, allows the computer to intelligently and automatically serve us. galvanized steel coils supplierWith the continuous evolution of this idea, a new language has emerged, namely computer language.

ThreeStagesoftheDevelopmentofComputer:MachineLanguage,AssemblyLanguageandHigh-level

In 1946, at the University of Pennsylvania, John W. Mauchly and J. Presper Eckert invented the world's first general-purpose computer, named "ENIAC." At that time, the programmer had to manually control the computer. The only person who thought of using the programming language to solve the problem was the German engineer konradzuse.

A brief history of computer language development

 

A computer is a combination of hardware that can perform powerful functions. The only thing he can recognize is logical operations, namely 0 and 1, so the original computer interaction language is a binary machine language, because it is too difficult to understand and remember. People define a series of mnemonics to help understand and remember, and gradually produce assembly language, but assembly is still difficult to understand and remember, and gradually developed a high-level language. With the birth of structured high-level languages, such as C and Fortran, programmers can leave the machine level and express their ideas through more abstract levels. At the same time, three important control structures are born, namely, sequential structure, selection structure, the loop structure, as well as some basic data types, are good for programmers to describe and abstract problems in a way that is close to the nature of the problem. However, as the scale of the problems that need to be dealt with continues to expand, the general programming model cannot overcome the error-expanding expansion of the code. At this time, a new way of thinking about programming and programming is emerging. That is, object-oriented programming, but also a number of computer languages that support this design model, such as C++, Java, Python, etc.
