WHAT IS COMPUTER PROGRAMMING FULL DETAIL ITS EXTRA KNOWLEDGE

What is computer programming?

In the world of technology, we frequently encounter terms such as “programming” or “coding.” Nowadays, computer programming is becoming increasingly popular. If you aspire to build a successful career in the field of Information Technology, learning how to program is essential. Today, let us explore this very subject—specifically, what exactly programming is and the various types that exist.

What constitutes a programming language? In this article, we will also discuss some of the most popular programming languages.

What is a Computer Program?

Before understanding what computer programming is, you must first understand what a computer program is. A computer cannot do anything on its own unless it is given an instruction.
It is the computer program—or software—that tells the computer what tasks to perform and how to execute them. In other words, your computer cannot perform any function without a program or software. A computer program is also referred to as software or a computer application.

What is Programming?

Programming is the process by which a computer program is designed. A program contains a series of instructions intended to solve a specific problem or perform a particular task, and these instructions are written by a programmer.
In this process, code is written using a programming language. Depending on the requirements, programming can range from being simple to being highly complex.
Programming is often referred to as “coding.” However, coding is merely one part of the programming process.

Steps of Programming

Programming involves several steps, five of the main ones being listed below:

Understanding the Problem:
First, the programmer must understand the problem that needs to be solved by the computer.

Finding a Solution:
Next, a solution to the problem is devised, and a plan is formulated.

Coding the Program:
To enable the computer to perform the task, instructions must be written; this involves selecting an appropriate programming language and writing the code.

Program Testing:
The developed program is tested in various ways, and the results are analyzed.

Documentation Preparation:
Separate documents are created to explain the program—such as end-user documentation, programmer documentation, operator documentation, etc.

What is a Programming Language?

A programming language is a type of computer language that programmers use to write code and create computer programs, software, applications, and more.

As you may already know, our computers understand only binary—that is, the language of 1s and 0s. In the early days of computing, programming was performed using this very language of 1s and 0s. However, understanding this binary language is an extremely difficult task for humans. This is precisely why programming languages ??were invented.

Essentially, a programming language acts as a bridge between us and the computer. It is important to note here that a computer does not directly understand the instructions written in a programming language; therefore, software is required to convert this language into binary code.

Types of Programming Languages

Programming languages ??are primarily of three types:
Machine Language
Assembly Language
High-Level Language

Let’s understand these in detail:

Machine Language

Machine language is a language that utilizes binary digits (0 and 1), wherein all commands are formatted using 0s and 1s—a format that a computer can easily comprehend. The computer’s CPU (Central Processing Unit) understands this language directly. It is the first-generation language of computers, and it is difficult for humans to understand.

Assembly Language

This is the second-generation language of computers. It is considered a low-level language. Instead of binary digits, it employs keywords. An assembler is used to convert Assembly language into machine code. It is slightly easier to understand compared to machine language.

High-Level Language

High-level programming languages ??are very easy to understand because they utilize English keywords and symbols. This type of language requires a compiler. The function of a compiler is to translate the high-level language into machine code. C, C++, PHP, JavaScript, etc., are examples of high-level languages.

Most Popular Programming Languages

While there are numerous programming languages ??in the world of computing, different languages ??are utilized for different tasks. Each possesses its own unique advantages and disadvantages.

Today, we are going to tell you about the most widely used and renowned programming languages ??across the globe:

Python

Python is a very popular programming language. Its key feature is that its syntax is extremely simple and user-friendly, making it very easy to learn. This is precisely why it is highly popular among beginners.
This is an open-source language. It is completely free, and anyone can learn it. In addition to being easy, it is also powerful. It is used in fields such as video games, data science, and artificial intelligence.
According to data from October 2020 provided by PYPL—a programming language ranking site—Python ranks number one globally. This ranking is based on Google Search statistics.

JavaScript

JavaScript is a highly popular frontend programming language. It is used to create interactive websites. It can function on both the server side and the client side. With the help of Node.js, web applications and games that run in the browser can be developed.
Since it is a widely used language, in terms of popularity, it ranks among the top programming languages.

According to Stack Overflow’s 2020 Developer Survey, JavaScript ranks first on the list of the top 10 programming languages ??and technologies.

Java Programming

Java has been used in the field of computer programming for many years and is highly popular among large organizations. A program written in Java runs on all devices that support Java.

As you are aware, the Android platform is extremely popular in its own right, and Java is used to build Android apps. To facilitate this, Google created Android Studio, a Java-based Android development platform.

According to the TIOBE Index, Java held the number one position for several years, but it now ranks second.

C# Language

C# (C Sharp) is a popular programming language developed by Microsoft. It is a very powerful language for the .NET framework. Its syntax resembles that of C and C++; therefore, if you are familiar with C programming, you can learn it with ease.

It is used for developing backend applications, Windows applications, games, and more. In terms of popularity, it currently ranks fifth on the TIOBE Index.

C / C++ Programming

In the field of programming, the C language is a long-standing veteran, and almost every programmer begins their journey of learning to code with it. It serves as the foundation for languages ??such as C++, Java, and JavaScript. Once you master this computer language, learning any other programming language becomes significantly easier.

According to the 2020 TIOBE Index, it holds the number one spot. Furthermore, in a survey conducted by Stack Overflow, C/C++ ranked between the seventh and eighth positions.

PHP Language

PHP is a popular scripting language used in web development. It is an open-source language that operates on the server side. Millions of websites across the internet utilize PHP, either directly or indirectly. You may be familiar with WordPress—the most widely used Content Management System (CMS)—which employs the PHP language in its backend.

Based on contributions to GitHub repositories, Octoverse has ranked it at number 4.

Conclusion – What is Programming?

The world of computers and information technology would be virtually impossible without programming. Programming possesses such immense power that, with its aid, humans today are able to operate critical systems—such as airplanes, satellites, and missile systems—using merely a few buttons and controllers.

Even if you do not belong to the field of computer science, you should still learn programming. Regardless of whether or not you choose to pursue a career in coding, learning it will bring about a significantly positive transformation in your cognitive and problem-solving abilities. Nowadays, even young children are being taught coding, and that is a very good thing.
