What are programming language generations?
programming language generations are a way to classify computer programming languages according to their total distance from the actual machine code that is generated, and in some ways easy to use by a programmer. There are three generally accepted generations of programming language and several of them whose definitions are not clearly agreed. The first generation computer programming language is a straight machine code without abstraction. Second -generation languages are an abstracted machine code, such as the assembly language that are bound to a specific system architecture, but are legible and need to compile. The most common are third generation languages, including standard languages such as C and Java®, while languages that are fourth generations or higher have different definitions. This means the first and second generates was only classified as such to emphasize the ability of third generation languages. The fourth and fifth generation of programming language was largely used as termsin relation to marketing for languages that were in development. In marketing and in some academic areas, generations of languages are used in a non -standard way to indicate that one language is more recent or has more functions than another.
The first programming language generation indicates the machine code. This means writing a program as a sequence of bytes or in extreme cases of bits that can be directly done by computer. In most cases, this applies to a system that receives input through hard switches or other physical mechanisms.
second generation programming languages are considered to be languages in the style of assembly. These are languages that are written with code and readable persons are still tied to specific systemic architecture, but represents an easier development environment and some abstraction. The mounting languages have never stopped using since 2011 and are not only extremely strongBut they can also be used as an inline statement in higher -level programming languages, which is a false idea that the generation of language is equal to its speed or strength.
Third -generation programming languages have separated the code from the processor to an even greater extent, allowing the development of the code that used more readable commands. In addition, compilers have been developed that could turn one line of code into several assemblies on multiple platforms and finally to dozens or more instructions on machine code. Almost all computer languages that can compile native binary executable files and libraries are considered to be third -generation languages.
In general, the fourth -generation language is perceived as a language to use some type of programming language that is very natural to users. It can also be defined as a language that uses visual elements to create a final program. The third definition is a programming language that is created for a specific purpose such as the Da programming languagetabasis or language of rapid application development (RAD).
The released definition of the fifth -generation computer language is one that allows the programmer to introduce a computer with a problem that is then trying to solve. Most of the languages that are listed as the fifth -generation language are mostly academic. Further generations of programming languages, such as the sixth and seventh, have been used by commercial language developers for marketing purposes.
