What Is Coding and What Is It Used For?
I have been asked numerous times what is Coding and what it is used for. I have decided to write this blog to explain in detail and define Coding and essential equipment and concepts.
Coding is the process of creating instructions for computers to follow. These instructions are written using programming languages, which allow humans to communicate with machines in a way that computers can understand and execute, also known as computer programming.
Coding is used for writing and giving instructions to the computer to do a specific task. For example, when we would like a web developer to create a calculator app, Coder writes the code/set of instructions for the computer or Robot for addition, subtraction, multiplication, and division. Once the code is run, the computer understands the inputs and provides the correct answer based on the given information.

Types of Programming Languages
There are two major types of compute programming languages. High-Level Programming Languages and Low-Level Programming Languages.
High Level Programming Languages
It is easier for humans to understand and provides a high level of abstraction. These are near to human language and allow programmers to express concepts more intuitively and readably. They are easier to debug.
Low Level Programming Languages
They require more understanding of the hardware and architecture. The code is faster and more efficient but more complex and harder to understand for humans.
Limitations of Machine Languages.
These languages are designed for the computer to understand easily. Humans usually have a more challenging time learning to code and understand them and write code in Machine Languages.
Complexity: The code is mainly based on 0,1. Computer programmers require a deep understanding of computer architecture and binary operations. It takes more work to write code in machine languages.
Lack of human readability: These languages are not easy to read and understand by humans. The code and data are presented in binary format, making it challenging for the programmer to comprehend and debug the program.
Prone to errors: Computer programmers are more susceptible to making errors due to these languages’ complex syntax. A simple mistake can lead to a program crash. Debugging these programs is also time-consuming and challenging.
Lack of Modularity: Machine languages need to support Functions, classes and libraries. It is challenging to reuse the written source code because the development increases. High-level languages provide abstractions, readability, portability and better productivity for software development. These languages are designed and developed for humans to understand quickly and are very near to human languages.
Famous and Widely used Languages.
Python is one of the most popular high-level programming languages and widely used languages. We quickly understand Python code as it is a high-level programming language. It is often used in Artificial Intelligence, computing data analysis, and scientific research.
Java: It is what is coding an object-oriented language general-purpose computer language. It is used in apps and large-scale computer systems. It is also a high-level programming language.
C++: It is an extension of the C language. It has both low-level and high-level programming language features. It is widely used in game development, system programming, and other critical applications, allowing direct memory manipulation, hardware access, and low-level operation. It also supports high-level functions like object-oriented programming.
Many other languages like Java Script, C#, Ruby, Swift, PHP, etc. Each one is used for different purposes.
How does Coding works?
Coding or computer coding is writing instructions for a computer to perform a specific task. Coders write code or a set of instructions using computer programming languages such as Python, Java, PHP, etc. which the computer understands.
General overview of how Coding works?
Programming Language Choice: There are many different coding languages available, and each of them has its grammar, syntax, and purpose. We select the programming languages as per our needs.
Design And Plan: Depending on the problem we would like to solve; we select the languages as per requirements. For example, HTML and Java Scripts and mostly used for web development. So when we are building a website, then we use these languages.
Writing the code: Before writing the code, we make a flow chart of how the process will work and then start writing the code. Writing the code includes syntax and rules of chosen programming language to write a code that the computer can interpret and perform certain tasks.;
It is a process of using machine code and identifying and fixing the errors in the machine code. The error may be syntax errors, logical errors, and not producing the right outcome. We can identify and resolve all these kinds of mistakes through debugging.
Testing: Testing the program after writing the code and fixing all the bugs is crucial. Through testing, we ensure that our program is producing the right results. It involves running the program and inputting the data with different variations. We try our best to include all the scenarios and try to break the code so we can fix any issue which we were not aware before.
How does computers work?
A Computer is a digital processing machine that converts the user or other inputs into binary numbers (1 and 0s). Its central processing unit (CPU) processes the information and provides the results on the output devices such as printers and monitors. The following are the basic components of a computer and how they work together to perform tasks.
Input Devices: These are hardware devices, such as a keyboard, mouse, microphone, scanner, Etc. Through these devices, users give input to the computer.
Central Processing Unit (CPU): The computer brain performs calculations and executes instructions. The CPU reads data from the computer’s memory (RAM), performs arithmetic and logical operations on the data, and then gives the results back in memory/Screen.
Storage Devices (SSD – HDD): These are hard disk drives (HDDs, older version of storage drives) and solid-state drives (SSDs) that provide permanent storage for data and programs.
Memory (Random Access Memory): It is a temporary storage space, and the computer stores data and instructions currently being used. RAM is temporary and loses its contents when the computer is turned off.
Output Devices: These are hardware devices, such as speakers, printers, and monitors. These devices allow the computer to display or output information.
Software And Apps: This is a set of instructions that tell the computer what tasks to perform. Operating systems (such as Windows or macOS) and applications (such as Microsoft Word or Adobe Photoshop) are software examples.
The Importance of Computers in Coding.
Most of the programs/software are written and executed on the computers. It is an indispensable tool for coders.
Code Execution:
Programmers/Coders write instructions for computers to perform specific tasks and rely on them to execute and produce a precise output. Computers can process and run code quickly, and programmers can test, debug and see the results of their programs.
Development Environment:
Programmers write and edit their codes using a computer platform. They use the IDE(Integrated Development Environment), text editors, and different software to write and execute these codes on the computers.
Translation to the computer languages As it is harder to write code in a machine language than languages for humans due to this, most coders write computer programs using high-level programming languages. When we execute the codes, computers translate them to machine languages first and then process the code. The process of translating the code to machine language is called compilation or interpretation of the code. Computers can do repetitive tasks without issues, and we can automate most of the functions. They can perform complex calculations and handle large amounts of data. Once you automate the computer program enough, then it runs without any issues.
Computers-Coding and Their Relationship with Humans
