The primary difference between client-side and server-side programming is simply where the script is executed. Client-side, for example, executes the program within the end-user’s own web browser and maybe be visible to the user if they check the source code for the page. JavaScript and VBScript are the most common languages used on the client-side. The advantage of using client-side scripting is that you save resources on the server by using the end-users hardware to execute the script as well as preventing the page from executing a PostBack (Fote, 2013). A PostBack occurs when a client sends a request to the server requiring a full refresh of the HTML on the page. This consumes a significant amount of resources. To circumvent this, a concept called Ajax was implemented. By using client-side scripts, web services can bypass the web server and access a database, in what is known as a CallBack. This prevents the entire page from refreshing and simply updates the page with the new data.

Server-side scripts, on the other hand, cannot be read by the user. They are executed completely on the web server before the page is sent to the client. Some of the most common languages for writing server-side scripts are Java, not to be confused with JavaScript, Python, and PHP. One of the advantages of using server-side scripts is their accessibility, they will generally output HTML and can therefore be run in any browser. Pages using server-side scripting are essentially everywhere. A good example would be WolframAlpha, which is an advanced search engine that can also perform complex operations and mathematics, all executed on the server-side.
