Many newcomers to programming make the error of choosing a popular language without a roadmap, i.e., without guidance. They’re going to hit a snag sooner or later. It is unusual for a potential programmer to take the effort to explain the many concepts, languages, and tools needed to be a good programmer.

In this essay, I will explain the necessary steps for every aspiring or established developer to do in order to be successful out there. I’d be discussing programming principles, languages, and tools that ordinary developers utilize. These stages were carefully chosen based on the author’s experience and regular research in the technology industry. This post is just intended to raise knowledge of key subjects that will help developers succeed in their area.


Understand computer architecture and data fundamentals

Abstraction is one of the most fantastic aspects of a contemporary programming language. Developers do not need to worry about hardware details and may instead focus on programming. It can narrow the extent of a skill’s understanding.

It is also critical to understand your computer’s architecture. Your computer’s essential components are housed on integrated circuits or microchips. Transistors are used to power these microchips. A single microchip may have millions or billions of transistors.


The Central Processing Unit is the computer’s brain (CPU). It is the area of the computer where logical activities like fetching, decoding, and executing instructions take place. Each CPU contains an instruction set, which is a collection of binaries (zeroes and ones). These are the commands that the CPU recognizes. Developers can avoid having to grasp this set of instructions by using abstraction.

The CPU is the logical component of a computer that can store data in both the long and short term (temporal). The computer uses Random Access Memory (RAM) for short-term memory, while the hard drive or ROM is used for long-term memory (Read Only Memory). It’s hard to discuss memory storage without mentioning what it stores (Data). At one level (high level), data can be seen as papers, multimedia, emails, files, folders, and so on. However, from the perspective of a computer chip, it is stored as ones and zeros known as bits. A byte is a group of eight bits that are used to store information. It may be anything like 00000001 or 01100110.



How does programming languages work?

We discussed binaries in the last section as commands that the computer understands. As a result, we can create code that tells the CPU what to do in a way that it understands. The machine code is the form that the computer understands. These codes are not like the ones we use every day. Python, JavaScript, and Java are examples of high-level programming languages.


A higher-level language is one that has human-readable instructions or syntax that is simple to learn. These languages serve as a link between how humans interpret the world and how machines comprehend the world.

A higher-level programming language may be either compiled or interpreted. Python and JavaScript are interpreted languages, whereas Java is a compiled language. We’d go into more detail afterwards.


How does the internet function?

The internet may be viewed as a global network of computers linked together to exchange resources (data). Data is shared in the form of ones and zeros, such as web pages, multimedia, emails, and so on. A network’s computers communicate with one another. If both are present and available, one opens the discussion and the other responds to it.


The computer that initiates the interaction is known as the client, while the computer that responds to the discussion is known as the server.


Assume you activated your web browser to reach “” The client in this example is the browser attempting to visit this page. The person attempting to view this page is also known as the client. When you finish putting the address into the search window and press enter, you are requesting to initiate a dialogue with the server that hosts the Facebook website. The server responds by transmitting the necessary data to show the Facebook web page. This is known as a reaction. If it is successful, the Facebook page is presented; otherwise, an error message is sent. This type of client/server interaction is used in internet data transfer.



Learn the fundamentals of command-line use

In movies, the command lines are frequently shown as a cryptic black screen with difficult-to-decipher or interpret characters. Behind the screen is typically a nasty hacker attempting to bring down a government or organization; other times, it’s a brilliant technician.

The command line is relatively simple to use and allows us to execute some of the things that the mouse’s point and click mechanism allows us to do. The only difference is that it requires the use of a keyboard.

You may use the command line to navigate between directories, create new folders, move files, copy files, remove files, run programs, and much more. A terminal is the window where you input all of the commands to accomplish operations on the command line.


Open the terminal program, which is a Unix Command Line Terminal, if you are using a Mac OS (Operating System). If you use an operating system that does not have a graphical user interface (GUI), such as Linux or Unix, you are already at the command line. If your Linux or Unix system has a graphical user interface, you should go to and open the program.

That concludes volume 1. In the following volume, we’ll look at how to run some simple commands via the terminal. Then we proceed on our journey to being a professional programmer.



Becoming a successful programmer necessitates time, money, and commitment; without these three tools, it is very difficult to create something awesome; good things in life necessitate a lot of commitment; follow the standard principle of learning programming and you will achieve programming knowledge as expected very soon.
