Computer programs or applications are used in almost all aspects of life from the search engines we use to the ATMs in banks.", "There are several programming languages but the most popular ones are the higher-level languages that are faster for humans to write but slower for computers to process. This is because they have to be compiled or interpreted.", "Programs which are interpreted(executed line by line) are called scripts. Interpreted programming languages are therefore called scripting languages. The majority of others are compiled into an unreadable(by humans) bytecode which is faster for a computer to run. Compiled languages run faster and are more suitable for large-scale apps.", "Many beginners are confused of what to learn. The field of ICT is a vast field. Some of the most popular sectors involving programming are:

Mobile app development
Web development
Desktop app development
Embedded Systems
Game development
Machine Learning
Ethical Hacking
Data Science

", "There are many mobile operating systems in the world that targeting all of them at once seems daunting. If you are interested in making mobile apps for all platforms learn Dart (and Flutter) or JavaScript. JavaScript has many frameworks for making native mobile apps the most popular being React Native.

For targeting specific platforms:

Android: Kotlin,Java or C++
iOS: Swift or Objective-C

", "Web development is into two categories: front-end and back-end. Front-end refers to the code executed on the user's browser after page load. Back-end refers to program executed on the server when the user requests to load a page. Every web developer must know the three basic front-end languages(HTML, CSS and JavaScript) and a back-end language. Back-end languages include PHP, Go, NodeJS, Ruby, Python, Java", "Java and C are used to make desktop apps for Windows, Mac and Linux. C# and .NET are best for making Windows and Linux applications", "Any language can be used to make games. What to consider in choosing a language is speed. Compiled languages like C++, C#, C and Java are best for making games." ]; function next(){ index++; if(index < lectures.length && index >=0){ document.getElementById("title_").innerHTML = lecture_titles[index]; document.getElementById("lesson").innerHTML = lectures[index]; } }
