Are websites like Facebook, Google, Youtube written in C ?

Question

Im a beginner, and surely big websites like those dont use HTML right?

Answer 1

Web site really are written in HTML. With that being said they also use other script languages to give them that interactive feel. There are quiet a few out there like JavaScript and VB Script. Most browsers have an option to view the source code for a web page. On FireFox it is under View -> Page Source. That will show you some of the source code to even this page. Good luck.

Answer 2

yes the backend usually is

since c++ is more faster

google use c++  and python and maybe some jave

i know facebook use php and c++  on backend and java to upload pics

Answer 3

One thing to remember that HTML is not a programming language. It's just a markup language. It's about how we want things are shown in browser(Firefox, IE, Opera). It has standar - like <img> for showing image -so that every browser would have the same behaviour when parse HTML code. Just visit this website http://www.w3.org.

With this condition no matter what OS/Platform we can always view webpages in the same way.(Actually It depends on how the browser translate HTML into their presentation page, but remember they do have same standards)

Programming language for website produce this html codes and give them back to the client. That's why the content could change(dynamic), because maybe it's connected to the database, time,user input/interaction and so on

I think big websites have more lot things to do with - maybe -query optimization, indexing database, cache, cdn, load balancing, have some servers, distribute database, clustering, bandwidths, etc. It has many factors.

The programming language is just  a preference. The main thing is about how good they implemented it in their websites.

And don't forget notice what is the concept of the website. Google and Yahoo! can be compared for the search engine. Google search engine implemented for fast searching and minimum image, differs from facebook. For facebook you should take the similar like friendster.

So , what do they use ?? Hmmm I don't have the answer for the server side programming. It could be php/java/ruby/asp/asp .net(vbnet/c#)   but gmail(google) and yahoo use AJAX as we can see in the client. Maybe they publish what do they use.
