Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/santanaservices/public_html/ on line 37

One of the most common questions we hear from individuals hoping to enter the IT industry is, "What programming languages do I need to know?" Obviously this is a complex question, and the answer will depend on what field the questioner is going into. Many programming languages are taught during courses used to obtain a computer information science degree. However, those already in IT know that the greatest skill you can have is to be a jack-of-all-trades. A well-prepared worker can switch between computer programming jobs with only minimal training, thanks to a wide knowledge of multiple programming languages.

Because of this, the quick answer to this question is, "As many languages as you can learn." Of course, if we took the time to learn every programming language possible, we'd never actually earn an income! This list covers the most essential computer programming languages a person trying to enter IT should know.

HTML, CSS and JavaScript

These three different languages are listed together because between them they make up the vast majority of website coding. Since the internet is now the dominant means of global communication, there will always be jobs in web design and development. HTML, CSS and JavaScript are similar in many ways, but each has a different capacity to improve website function.

HTML stands for Hyper Text Markup Language and is the basic language of websites. HTML is used to insert images, links, basic formatting and content onto a webpage. It's one of the easiest and usually the first programming language aspiring computer programmers should learn.

CSS is a natural extension of HTML that introduces more features to a website. CSS, or Cascading Style Sheets, allows for complex websites with constant formatting, by making individual web pages call up a separate piece of code that determines elements on the page. This allows for cleaner coding and a separation of layout and content.

JavaScript allows for client-side interactivity on a webpage and is designed to blend seamlessly with HTML and CSS. Text boxes, buttons and popups are all functions of JavaScript.

Programming LanguagesJava

Java is similar in many ways to JavaScript, but is in fact unrelated. It's an object-oriented language with many uses, and is designed to be both intuitive and stable. Java's versatility and widespread use makes it handy for developers, and it'd be nearly impossible to find a successful programmer who didn't know it like the back of his hand.

Java is most often seen in web applets, where it can run more advanced GUI's than JavaScript. Many online games run through Java. It is not a particularly fast or powerful language, but it can do practically anything and is almost universally understood across different machines and operating systems. Because of this, it's a programming language every computer programmer should know.

C and C++

These two languages are old classics still widely in use today. C was developed in the 1970's and originally meant for use in systems programming. However, it soon became popular for consumer software as well thanks to its efficiency and versatility.

C++ was designed as an expansion to C in 1983. It is now one of the most popular of programming languages, and can be used for nearly every application. As one of the best developed and powerful programming languages in use, it is essential for computer programmers to know. If you can only learn one language, learn C++.


PHP is a server-side language that allows for interactive web pages. It is designed to use tags, and can thus be integrated with the basic HTML of a page. This may sound similar to JavaScript, but the key difference is that JavaScript works solely on the client-side. There are many occasions where having the interaction go through the server is desirable, and that's where PHP really shines. PHP also works well with with Java, making it easier to call Java methods in your code. Combined with its compatibility with many types of databases, it's easy to see why PHP should be in every programmer's arsenal.

How to Learn Programming Languages

The languages above will generally be enough to start with in IT, but there are a few more that you may come across. Ruby, Perl and Python are all commonly used in advanced projects, so if you have the time they're well worth looking into. And of course, specific assignments may require any one of the many programming languages out there.

The amount of languages a professional computer programmer needs to know can be intimidating. Not everyone has the time or money for formal education, and free resources on the web are often hard to follow, inaccurate or incomplete. One of the best ways to pick up a new language is through online video courses. has partnered with VTC to bring you comprehensive, easy to follow instructions at affordable rates. Don't let yourself fall behind in this competitive industry. Brush up on your programming languages today! "

Now that you've gotten free know-how on this topic, try to grow your skills even faster with online video training. Then finally, put these skills to the test and make a name for yourself by offering these skills to others by becoming a freelancer. There are literally 2000+ new projects that are posted every single freakin' day, no lie!
