A programming language is a computer language that programmers use to implement a piece of software to run on computers or to write a set of instructions to perform some task on a computer. In simple words, we can say that a language used by programmers to communicate with computers is called a programming language. With the help of programming languages, programmers can develop many types of applications, such as web, desktop, games, mobile, and many more. Many programming languages are available to do this task, such as C, C++, Java, Python, PHP, etc.

In addition, each programming language consists of two components: syntax and semantics. These are the language rules that a programmer has to follow to write a program. Once the programme is written, it is compiled and converted into machine code. As computers only understand machine language, transforming it into machine code is necessary. This article will discuss all the essential topics of a programming language, such as its history, the need for programming languages, the top programming languages to learn, and many more. I hope this article helps you understand the concepts clearly.

History of Programming Languages

As we discussed earlier, programming languages are used to communicate with computers. The sets of instructions that are given to a computer to perform some task are written in programming languages. If we talk about the history of programming languages, the first-ever programming language was written by Ada Lovelace, a mathematician, in 1843. It was a machine algorithm, and Ada wrote it for Charles Babbage’s Difference Machine. This invention was considered the foundation for all programming languages.

At that time, programming languages were complicated machine codes. In 1949, to simplify the complexity of machine code, assembly language was created. It was a low-level programming language used in the Electronic Delay Storage Automatic Calculator (EDSAC). In the same year, another language, Shortcode, was invented. It was considered the first high-level language for the electronic computer. The first compiled computer programming language was Autocode, developed by Alick Glennie in 1952.

John Backus created FORTRAN, another programming language, in 1957. The primary motivation for this advancement was to perform high-level scientific, mathematical, and statistical computations. FORTRAN is still used on advanced supercomputers today. ALGOL (Algorithmic Language) was created in 1958. ALGOL was regarded as the starting point for the development of several important programming languages, including Pascal, C, C++, and others.

After that, many changes were made to programming languages. Many new languages were created, with the majority of them based on the concepts of older programming languages. They made programmers’ jobs easier and more straightforward by adding new programming features. Today, there are thousands of programming languages that have evolved into an essential component of computer programming.

Why do you need Programming Languages In Computers?

Programming languages act as a bridge between a human being and a computer. We all know that computers can not understand human languages. If we want to perform some task on a computer, we have to give instructions that the computer can understand. Programming languages allow us to provide those instructions in a way that a computer can understand. There are many programming languages available for this purpose. Each language has its own distinct features, along with some standard features as well.

Furthermore, programming languages enable developers to create more complex programmes with fewer resources. Programming languages support programming in all areas, from computational science to artificial intelligence applications. Furthermore, programming languages enable developers to create software that is independent of the operating system. Users will be able to run the software on any device or platform as a result of this. Furthermore, programming languages enable a developer to automate a task that he must perform repeatedly. Many programming language features, such as loops, functions, events, and so on, can be used to accomplish this.

With the help of programming languages, all computer software problems can be quickly resolved. Almost everything that we can do on computers is only possible because of programming languages. Computer programs run on every laptop, and programming languages are the basis of those programs. All types of programs, such as scheduling software, online games, virtual reality, and many more, can be made with the help of programming languages. The programming languages used in these programmes help the computers perform tasks accurately and efficiently.

Furthermore, computer technology has developed rapidly, and programmers are working on learning new ways to communicate with computers. This led to the development of new programming languages because they allow computers to execute tasks on time at high speeds. After discussing all this, we can say that programming languages are an essential part of computers and help computers efficiently perform several tasks.

Different types of Programming Languages

If we talk about the types of programming languages, there are thousands of programming languages available now, and each language has its own syntax and purpose. Every programming language has its own syntax for writing a programme or any specific application. According to their syntax and purpose, these languages can be classified into three categories: machine language, assembly language, and high-level language. Both machine and assembly languages are also known as low-level languages. Let’s discuss them in detail.

1. Machine Language

Machine language is the oldest programming language and is also called the “fundamental language of computers.” It is a low-level programming language that is sometimes called machine code or object code. A machine language consists of numeric codes known as binary digits 0 and 1. A computer directly executes these binary digits to perform an operation, and there is no need to translate the code. It is difficult for a human being to understand this code, but it can be easily understood and read by a computer system.

Furthermore, there is no need for compilers and interpreters in this type of language, so machine language programmes run very fast. But there are some disadvantages to this language also. It is a complex language, and it is not easy to write programmes in this language. We cannot use a programme written in machine language on another computer because it is not portable. The maintenance of programmes written in machine language is also very high.

2. Assembly Language

The Assembly language is also a low-level programming language. It is an extended form of machine language. In assembly language, instructions are written in symbolic code instead of binary code. Symbolic codes are human-readable codes such as sub, add, mul, etc., where sub is used for subtraction, add is used for addition, mul is used for multiplication, and many more codes are used that can be easily understood by a human being. Because of the use of this symbolic code, this language is also known as a low-level symbolic language.

In addition, it is an easy task for a programmer to find errors in programmes written in assembly language because they are easier to find and correct. Moreover, programmers don’t need to track the storage location of the data. Instructions in the programmes can be easily corrected and modified also. But there is a need for a translator in this language because computers can only understand the machine code.

Assembler is used in the assembly language to convert the assembly code into machine code. A programmer must understand the logical structure of the computer on which he is working in order to write a programme in assembly language.Just like machine language, assembly language code is also not portable. Some examples of assembly languages are ADA, PASCAL, etc.

3. High-Level Language

High-level languages are closer to human beings than other machine-level languages. All the old programming languages had portability issues. It was difficult for a programmer to transfer the programme to other machines. To resolve this issue, high-level languages were developed. Code is independent of a computer system in high-level languages and can be easily transferred to other systems. Furthermore, the syntax of high-level languages is user-friendly. Any human being can easily understand it. It is easy for a programmer to write a programme in a high-level language, and it is also a less time-consuming process.

Moreover, it is an easy task for a programmer to detect and remove errors in high-level languages. A large number of built-in functions are also provided in these languages that can be used in the fast development of a program. But the high-level language programmes are less efficient because more time and memory is needed to execute a program. A translator programme is also required in high-level languages to translate the source code into machine code. Some examples of high-level languages are FORTRAN, COBOL, BASIC, C, C++, Java, etc.
