Web technology is a small but reliable section of Computer Science teaching papers. DSSSB, KVS, NVS, and state TGT and PGT exams expect a teacher to understand how the web works well enough to explain it to a class, so the questions stay at a foundational level: what HTML is, how a browser and server talk, what a URL contains. Our published question bank carries over 200 questions tagged to internet and web technology, and they cluster around exactly these basics.
This is a ground-up walk-through of that section: the client-server model, HTTP and URLs, DNS in brief, HTML structure with a small page you can read, static versus dynamic pages, and the authoring tools a teaching syllabus names. This is deliberately the teaching-level view; a deeper, exam-numerical treatment of the same protocols for GATE is linked at the end.
The client-server model
The web runs on a client-server model. Your browser (Chrome, Firefox) is the client; it requests pages. A web server is an always-on machine that stores those pages and responds to requests. You type an address, the browser sends a request, the server sends back the page, and the browser displays it.
That request-response cycle is the mental model everything else hangs on. The client asks, the server answers, and the network in between carries both. A teaching paper tests that you can state this cleanly, not that you can time it.
URLs, HTTP and DNS
A URL (Uniform Resource Locator) is the address of a web resource. Break https://www.example.com/index.html into its parts:
https is the protocol (HTTP secured with encryption).
www.example.com is the domain name of the server.
/index.html is the path to the specific page on that server.
HTTP (HyperText Transfer Protocol) is the set of rules the browser and server use to exchange pages; HTTPS is HTTP with encryption for safety. DNS (Domain Name System) is the internet's directory: it translates a name like www.example.com into the numeric IP address the network actually routes to, because computers locate each other by IP, not by name.
At teaching level you need the roles, HTTP carries the page, DNS turns a name into an address, HTTPS adds security, not the round-trip counting a networking exam demands.
HTML: the structure of a page
HTML (HyperText Markup Language) is the language that structures a web page. It is not a programming language; it is a markup language, describing content with tags. Tags usually come in pairs, an opening <p> and a closing </p>, wrapping the content they format.
A minimal page has a fixed skeleton:
<html>
<head>
<title>My Class Page</title>
</head>
<body>
<h1>Welcome</h1>
<p>This is a paragraph of text.</p>
<a href="notes.html">Class notes</a>
</body>
</html>Read it structurally:
<html>wraps the whole document.<head>holds information *about* the page, here the<title>shown on the browser tab.<body>holds the visible content:<h1>is a heading,<p>a paragraph, and<a href="...">a hyperlink to another page.
The common tags a paper expects you to know: headings <h1> to <h6>, paragraph <p>, line break <br>, bold <b>, italic <i>, image <img>, hyperlink <a>, and list tags <ul>, <ol>, <li>. The single most tested fact is that HTML is markup, not programming, and that most tags come in open-close pairs.
Static versus dynamic pages
A key distinction teaching papers draw:
A static page shows the same fixed content to every visitor. It is plain HTML, served exactly as stored, and changes only when someone edits the file.
A dynamic page is generated on request and can differ by user, time, or input, for example a page that greets you by name or shows today's date. It uses server-side processing or scripting to build the content.
The exam framing: static is fixed and pre-written; dynamic is generated and can change per request. You may also meet client-side scripting (JavaScript, running in the browser) versus server-side scripting (running on the server before the page is sent), and the idea that CSS (Cascading Style Sheets) handles the *look* of a page while HTML handles its *structure*.
Web-authoring tools
A teaching syllabus expects awareness of how pages are made:
Text editors like Notepad, where you write raw HTML by hand.
WYSIWYG editors ("what you see is what you get"), which let you design a page visually while the tool generates the HTML underneath.
A web browser as the tool that renders and tests the page.
The one term worth fixing is WYSIWYG: you edit the visual result directly and the HTML is produced for you, the opposite of hand-coding in a plain text editor.
How web technologies are tested in teaching CS exams
Teaching papers keep this section at recall and simple application:
HTML tags and structure. Identify what a tag does, complete a skeleton, know that HTML is markup and tags pair up.
Definitions. What HTTP, HTTPS, URL, and DNS each mean; what CSS is for.
Distinctions. Static versus dynamic pages, client-side versus server-side scripting, WYSIWYG versus a plain text editor.
Every official specific, the number of web-technology questions, the marks, and the exact sectional split, lives in the recruiting body's notification and varies across DSSSB, KVS, and state cycles, so confirm it there. The concepts here are stable and are exactly what our internet-and-web-technology questions test.
The short version
Web technology for teaching exams is foundational: fix the client-server request-response cycle, break a URL into protocol, domain, and path, know that HTTP carries pages while DNS resolves names, and read a minimal HTML skeleton confident that HTML is markup with paired tags. Keep the static-versus-dynamic and structure-versus-style (HTML versus CSS) pairs straight.
If you want this section sequenced with the rest of the syllabus, the Teaching Recruitment Exams bundle covers it with the CS core, and the DSSSB TGT Computer Science bundle targets the Delhi papers. This post stays at teaching depth on purpose; if you also sit GATE or want the exam-numerical treatment of the same protocols, DNS resolution steps, HTTP methods and status codes, read the deeper application layer protocols: DNS, HTTP and email deep-dive.
