A web application is software whose code resides on a web server. The user accesses the application using a web browser, over a network, usually the Internet or intranet. Web applications have become an integral part of life. For example. rarely does any person today, use internet mail ie. email (Gmail, Yahoo, Hotmail, ...), which actually represent web applications. When you read a newspaper on the internet, that website is powered by a web application. Social networks (facebook, twitter, etc.) are also web applications. Buying used cars online, reading newspapers or daily horoscopes electronically are also web applications.
Websites are created with different technologies and in different programming languages. They can be made completely "from the beginning" using HTML and css, but usually the appropriate framework is used, which already has some of its program elements written according to the appropriate rules and the programmer just develops the application on that framework.
There are also programs that make it easy to develop and administer a website, CMS (Control Management System), which is used to create the majority of existing websites. Examples of CMS are: Wordpress, Joomla, Drupal, Magento, etc. The programs that are most popular for creating web applications are:

​They are used to design websites. HTML is a markup language for creating the appearance of web pages and is used in combination with CSS. With the knowledge of these two languages ​​it is possible to create static web sites. Javascript has to be used to get better functionality.

​There is a version for the server and for the client side of the web application. The server version is Node javascript. With this language we can add functionality to the website, ie. make a dynamic website. The simpler version of javascript is jquerry.

​Java is used for both desktop applications and web application creation.
Java is used often to build server applications for video games and mobile applications. It is also the cornerstone of Android application development, making it a favorite of many developers. With its mantra (write once, run anywhere), it is designed to be portable and easily mobile from multiple software platforms.

​PHP, together with databases such as MySQL, is an essential tool for building web applications. It provides great power and is only the heart of orginal sites such as WordPress and Facebook. It is an open-source language, so there are a bunch of free pre-installed modules that you can adopt and modify to get the best results. It belongs to easier languages, requiring developers to simply embed (embed) code into HTML.
There are numerous frameworks that help build a web application in PHP, the most popular of which are Laravel, Zend Simphony, Yii, etc.

This language was designed by the Japanese Yukihiro Matsumoto with the idea of ​​making a language that is easy to use, so it was made for the needs of programmers and not for computers.

It was created by Larry Wall, initially designed for text processing.
It is a general-purpose language, among other things, for network programming and system administration. Perl was the language of choice for developing WWW applications in the mid-1990s. From the outset, it's the language of Unix and Linux system administrators who use it in their daily work primarily to automate the process. Today, there are also a number of custom commercial applications written in Perl.​

A mobile application is application software designed to work with smartphones (tablets), tablets and other mobile devices.
Here we distinguish:
Native mobile apps. These are applications made using the SDK (software development kit) and the programming language of a particular mobile platform (Android, iOS, for example), the main feature being that this application is mainly tied to one platform or its operating system. For example. an application made for the Android operating system cannot be used for iOS.
Web mobile applications. They are not platform related. These are actually web applications that are customizable on mobile
Hybrid mobile applications. They are a workaround for web applications. It is a native application made for a specific platform, which executes a web application in the components for going to the web.

​People's motivations for programming are different - someone wants to start a programming career, while to someone, programming is just a useful addition to skills in another area. There are also those who teach it so they can start an online business, or automate some boring business.
Application programming is a very broad term because there are a number of applications for different purposes, so we have applications that run on a local computer (desktop or native) applications such as. Mozzilla Firefox, CCliner, MSWord. On the other hand, we have programs related to the operating system, programs that manage various hardware devices (driwer). Programs that reside on a remote server and are accessed through a client on a local computer (a client program is a program that communicates with a server from a local computer over the Internet) are web applications.
Writing programs for communication between various devices that send data to a common platform (Internet of Things-abbreviated IoT) is becoming increasingly popular.
Therefore, there are a number of different programming languages ​​used to program applications. One programming language is not suitable for all these numerous applications but for a specific type of application, so we can classify programming languages ​​into several branches:

Even nowadays, when an internet signal is available at almost every turn, there are times when we are not online. For example, on a train, bus or plane, we can run out of internet, and we can use the time we travel to do some of the work. Maybe we are working on a remote construction site where there is no mobile signal? What if we went abroad, did not have WiFi access, and did not want to pay for roaming? These are also situations where we can only finish a job using desktop or native applications.

In their daily work, engineers use applications that require great computing power to model, design and simulate different processes. You guessed it, these are desktop applications.

​Language C is great if you are still in school, if you are very young and have a lot of time, and if you want to start learning from the root. It was as if you were starting to learn foreign languages ​​with Latin or Indigenous. You will have a broad education and it will still be much easier for you. Still, this is one of the hardest languages, not necessary, and certainly not the happiest choice for a first language, if you haven't had any programming experience so far.

​He is at the very top of popularity and is highly sought after by the non-stock market. Still, it is quite difficult and again not the best choice for beginners. It is good for programming computer games, memory-intensive desktop applications, consoles and mobile devices

It has been 20 years since its inception and has seen a surge in popularity over the last 10 years. In the most famous list in terms of the presence of programming languages, it holds a convincing first place for a long time.

Language is not one of the easiest to learn, but it is not overly difficult.

​C # is the primary language for development on Microsoft platforms and services. None Used to create modern web applications using Azure or.NET, but also applications for Windows devices and desktop applications for their own purposes.

​It is a general purpose language, but it is also used for web application programming. Python is often said to be one of the easiest languages ​​to learn because of its simple syntax. Python was created in 1991, is easy to learn and has a great library for developing software for scientific purposes, e.g. for the development of "artificial intelligence".

1. Machine learning and artificial intelligence (AI)
   - Increasing application in various industries, from healthcare to finance.
   - Tools and frameworks like TensorFlow and PyTorch are very popular.

2. Development in the cloud (Cloud Computing)
   - Increased use of platforms such as AWS, Azure and Google Cloud.
   - Focus on scalable and flexible applications.

3. Internet of Things (IoT)
   - Growing need for software that can manage connected devices.
   - Languages ​​like Python and C are often used.

4. Containerization and microservices
   - Using tools like Docker and Kubernetes for scalable applications.
   - Microservice architecture is becoming a standard for complex systems.

5. DevOps
   - Integration of development and operations for faster software delivery.
   - Tools like Jenkins, GitLab CI/CD and Ansible are widely used.

6. Development of mobile applications
   - Frameworks like React Native and Flutter are growing in popularity.
   - Focus on hybrid applications that work on multiple platforms.

7. Software Security
   - Increased focus on security due to growing threats.
   - Practices such as DevSecOps (security integration into DevOps) are on the rise.

These trends and languages ​​show how technology evolves and how developers must constantly adapt to new tools and techniques.
