Many possibility. C is one of them.
You can't. Sessions are a server-side technology. To properly implement a session, you have to use a server-side language like PHP, ASP, or Ruby.
Yes, JavaScript was (and is) used server-side. In 1994, Netscape released their Netscape Enterprise Server, which allowed for the use of JavaScript as a server-side language. It was never really hugely popular. But Apache still makes available their "mod_js" for this express purpose. (Even if it's not intended as production use, rather described as "just a toy.")
Javascript is a client-side script, meaning it runs only in the browser. It has no access to the server. For access to the server, thus creating a back-end, you need to use a server-side scripting language such as ASP or PHP. If you want to make a more fluid interface, JavaScript and AJAX can be combined with one of the two aforementioned server-side scripts, effectively creating a back-end and a front-end.
Client side scripting is a script, (ex. Javascript, VB script), that is executed by the browser (i.e. Firefox, Internet Explorer, Safari, Opera, etc.) that resides at the user computer. Server side scripting, (ex. ASP.Net, ASP, JSP, PHP, Ruby, or others), is executed by the server (Web Server), and the page that is sent to the browser is produced by the serve-side scripting. So when a server sends out a page, it executes server-side scripts, but does not execute client-side scripts. Once the browser receives the page, it executes the client-side scripts. Server side scripting can connect to databases that reside on the web server or another server reachable from web server. Client side scripting cannot do that. Server side scripting can access the file system that reside at the web server, client side cannot. Server side scripting can access settings belong to Web server while client side cannot. Client side scripting can access files and settings that are local at the user computer. Client side scripting consumes cycles from user's computer not web server one, while server side scripting consumes cycles form web server one.

It is not impossible to code on server side using javascript as there are frameworks available today which lets use of javascript on server side. But usage of this is not that high as most people prefer the normal way of using AJAX if they want javascript to interact with a server side language.
HTML is client side scripting so the Form will have to be in HTML (unless you use something like Flash or Java) and the submission will require a Server side language in order to do anything with the code. So to answer your question, you do not have to use HTML; you do not have to use PHP.However you will have to use a Client Side Scripting language like HTML and a Server side scripting language like PHP.
You use SQL by issuing commands to an SQL server, either directly by you or by a program you are using.

with just plain HTML its .HTML, but if you want to use a server side language like php it will be .php
There is no server side OS available yet.
You can use one of the server side scripts/language like PHP or ASP.NET among others to fetch data from server dynamically. You could also use AJAX if you want asynchronous data
In order to restart your server, you must close the program you use to host the server, and then just reopen it.

Java Server Page is a standard Java extension that is defined on top of the servlet Extensions. The goal of JSP is the simplified creation and management of dynamic Web pages. JSPs are secure, platform-independent, and best of all, make use of Java as a server-side scripting language.
Hypertext Markup Language or HTML is the code used to build web pages by describing content with the use of tags such as <table> or <form> or <p> for paragraph etc. HTML is executed on the client side which is the users PC. Browsers (IE, FireFox, Chrome etc) use these HTML tags to display content on a web page, such as an image or text or whatever content the author wants displaying to the user. Published web pages containing HTML exist on a web server and indeed, through the use of web server scripting, HTML can be generated and then sent to the users browser, but this still means it is a client side language.
