Programming Languages
A programming language is simply a set of rules that tells a computer system what to do and how to do it. It gives the computer instructions for performing a particular task. A programming language consists of a series of well-defined steps which the computer must strictly follow in order to produce the desired output. Failure to follow the steps as it has been defined will result in an error and sometimes the computer system won’t perform as intended.
Markup Languages
From the name, we can easily tell that a markup language is all about visuals and looks. Basically, this is the primary role of markup languages. They are used for the presentation of data. They determine the final outlook or appearance of the data that needs to be displayed on the software. Two of the most powerful markup languages are HTML and XML. If you have used both of these two languages, you should be aware of the impact that they can have on a website in terms of the aesthetics.
Scripting Languages
A scripting language is a type of language that is designed to integrate and communicate with other programming languages. Examples of commonly used scripting languages include JavaScript, VBScript, PHP among others. There are mostly used in conjunction with other languages, either programming or markup languages. For example, PHP which is a scripting language is mostly used in conjunction with HTML. It is safe to say that all scripting languages are programming languages, but not all programming languages are scripting languages.
