If you have been programming for a while and want to learn programming, then you may be thinking about what a good programmer is ? What can computer science graduates do to prepare for software development and programming careers?

The expectations for junior developers are some common questions we receive from our students .

In this article, RBK shares with you the most important things To provide you with a good starting point for things a programmer should know.

If your goal is to pursue a career in software development and find a programming job, then you can learn and improve these contents to maintain your leading position in the competition.

Without further ado, here is a list of things that every programmer should know, no matter what he is doing. These are basic skills that can serve you for a long time.

Any investment in these skills in time, money, and energy will help you reap the rewards throughout your career.

## Data Structures and Algorithms

If you want to be a programmer, then you should have a good understanding of data structures and algorithms.

This is one of the important topics in any programming job interview, and if you don’t understand basic data structures (such as arrays, linked lists, maps, collections), you cannot write actual applications.

This is why every programmer should work hard to learn data structures and algorithms in their computer science courses.

Even if you are a self-taught programmer, you must understand data structures and algorithms. In fact, Our programming boot camp at RBK will first teach you data structures and algorithms.

## Source Control

Source code control is used to store code. If you want to become a coder or software developer, you must understand version control tools such as Git and SVN.

Fortunately, Git and Github have simplified the market, and now more than 70% of organizations use Git, so you may be able to get out of trouble just by learning Git.

By the way, you should put in some effort to learn Git, and you should be familiar with advanced version control concepts such as branching and merging and the tool itself using the command line and GUI.

## Text Editors

when you work as a programmer, you should use a text editor. Even for non-programmers and anyone who uses computers, it is one of the essential tools.

Most of the beginner programmers mainly use NotePad in Windows and Linux VIs, but as far as advanced editors (such as Sublime and VSCode) are concerned, you have many choices, which provide IDE-like functions.

We suggest you take some time to learn your favorite editor and keyboard shortcuts, you can learn some efficiency tips.

## IDEs

For any programmer, a modern IDE is the most important tool. For C, C++ and C# programmers, the choice is clear: Visual Studio. For Python developers, Jupiter Notebook is getting better and better every day.

For Java programmers, there are three main IDEs to choose from: Eclipse, NetBeans and IntelliJ IDEA.

Although Eclipse is good, IntelliJ IDEA may be the most powerful of them. If you happen to be a fan of IntelliJ IDEA, it is recommended that you use IntelliJ IDEA skills to improve the productivity of Java developers in order to better learn IDE.

## Database and SQL

SQL is classic. It has existed for more than 30 years, and  it will exist for another 30 years. Considering the ubiquity of databases, the programmer hopes that he is familiar with basic database concepts, such as normalization and table design, and SQL.

There are many databases, but knowing only one is enough. The key is that you should be familiar with databases. You should know how to insert/update/delete data and write SQL queries to retrieve data.

Advanced conceptual knowledge such as adding aggregate functions is a big gain.

## UNIX or Linux
Like SQL, UNIX has withstood the test of time. It has been around for more than 30 years, and we hope it will continue to exist in the next few years.

Since most programmers have to work on Linux machines at some point, a deep understanding of the Linx command line is a long way away.

It enables you to work effectively. You can search for files, understand the operating status of the system by checking CPU and memory usage, and perform basic and advanced tasks.

## Programming Languages
As a programmer, you must know a programming language: C++ or Java, or maybe Python or JavaScript. You can choose anything you want, but my personal recommendation is that you should at least understand Java.

Getting started is very easy, which is why beginners are a good choice. It is also powerful, allowing you to perform almost any operation.

It allows the library to go from basic work such as Web development to more complex tasks using Big Data.

## Networking Basics
Today’s world is an interconnected world. No matter where you are, you can find a computer network, starting from your home, where you can use Wi-Fi through many devices, to schools, colleges and schools that use local area networks (LAN) to the Internet. office.

Most of the applications you will write will also not be stand-alone, but client-server type applications where requests will reach the server through the network. Customers can access your application from anywhere in the world.

Most importantly, you must understand the basics of networking to understand, develop, and support your application.

## Scripting Languages
In the previous point, we asked you to learn a programming language, but here, we ask you to learn a scripting language? why? Can’t the same programming language be used as a scripting language?

Well, of course there are some languages ​​that are good for OOP coding and scripting in Python, which is why you must to learn it. However, if you happen to learn C/C++ or Java, you will not be able to complete the learning as quickly as a Python or Perl developer.

The scripting language can easily create tools and scripts to solve common problems in the programming field. If you have good commands for scripting languages ​​such as Python, then you can easily automate ordinary tasks.

Computer science graduates and people who aspire to become programmers can use this list to learn about the things, tools, and skills of becoming a successful programmer.
