BCA 105T Notes for GGSIPU Web Technologies BCA Sem 1

BCA 105T Web Technologies at a glance: GGSIPU BCA Sem 1 credits, units and exam pattern

BCA 105T is where you start building websites: structure in HTML, style in CSS and Bootstrap, behaviour in JavaScript, data in XML. The facts below come from the GGSIPU BCA First Year syllabus:

No coding background is needed. The course outcomes ask you to build static pages and to write JavaScript that checks forms and changes content, so in these notes every syllabus tag or property comes with code you can run. It is one of the seven theory papers in the GGSIPU BCA Semester 1 papers.

BCA 105T Web Technologies Notes unit-wise: 44 code examples and 60 solved two-mark questions across 4 units

Notes for every other BCA paper are listed under GGSIPU BCA notes.

BCA 105T Unit 1: World Wide Web and HTML Overview

Part A explains what happens after you type a URL. DNS finds the server's IP address, the browser sends an HTTP request, and the server replies with HTML and a status code like 200 or 404. It also compares static and dynamic sites.

Part B is the HTML toolkit: structure tags, text formatting, entities, links, images and sound, lists, tables with rowspan and colspan, frames and <iframe>, forms, and image maps.

Remember: HTML is a markup language, not a programming language. It has no loops or conditions.

The Part A ideas of URL, WWW and the client-server model also appear in BCA 103T Unit 4 (Basics of Internet), so studying it once helps both.

BCA 105T Unit 2: Cascading Style Sheet and Bootstrap Basics

Part A makes the page look good: inline, internal and external style sheets, the cascade that decides which rule wins, <link> versus @import, and the box model of content, padding, border and margin.

Part B uses Bootstrap 3, because the syllabus names the jumbotron and glyphicons, which later versions removed. It covers the viewport tag for mobile screens, containers, the 12-column grid with xs, sm, md and lg breakpoints, and classes for tables, images, buttons and typography.

Remember: when two rules clash, inline beats internal, internal beats external, and !important beats them all.

BCA 105T Unit 3: Introduction to JavaScript

The programming unit: var, let and const, data types and operators, then if-else, switch and loops. After that come the alert, confirm and prompt dialog boxes, and built-in and user-defined functions.

The second half works on real pages: the String, Math, Date and Array objects, events like onclick, a registration form checked with onsubmit, the DOM tree, and BOM objects such as history and location.

Remember: prompt() always returns a string, so convert it with Number() or parseInt() before you add.

If-else, switch and loops work here the same way as the C control structures in BCA 101T Unit 1.

BCA 105T Unit 4: XML and Web Hosting Concepts

Part A is about XML, which carries data while HTML displays it. It covers naming rules, the building blocks of a document, the HTML vs XML difference, DOM and SAX parsers, and internal and external DTDs with a library example. It ends with XML shown through CSS or JavaScript.

Part B follows a finished site onto the Internet: the domain name hierarchy and DNS, physical and virtual domains, registering a domain, why IP addresses are needed, hosting types and the steps to publish.

Remember: an IPv4 address is 32 bits, written as four numbers like 192.168.1.10; IPv6 is 128 bits.

How to write BCA 105T answers: ten-mark HTML, CSS, JavaScript and XML code answers with an output sketch

For the two-mark questions in Q1, write two or three lines: a definition, then one tag, property or example. For the ten-mark unit questions, write code.

At the end of each unit, the notes give an answer order that fits that unit:

Small slips cost marks: watch for </br> (empty tags have no closing tag), color=red instead of color: red;, onsubmit="validateForm()" without return, and <Name>...</name> in XML, where the case must match.

Worked example: a predict-the-output question

Code: "5" + 3 + 2. Output: "532". Why: JavaScript reads from left to right. A string plus a number joins as text, so "5" + 3 becomes "53", and then "532". Write the output, then the reason. Unit 3 has 14 of these.

You can practise this answer order on the GGSIPU BCA important questions for other papers too.

BCA 105T exam corner: 60 solved two-mark questions and 46 ten-mark questions by unit

Every unit has 15 two-mark questions with written answers. Each ten-mark question points to the topic, figure and code that hold its answer.

One exam-style question from each unit, with the answer in short:

• Unit 1: What is the difference between cellpadding and cellspacing? Cellpadding is the space inside a cell, between its border and the text. Cellspacing is the gap between two neighbouring cells.
• Unit 2: Differentiate between margin and padding. Padding is inside the border and takes the background colour. Margin is outside the border and is always transparent.
• Unit 3: What is the difference between == and ===? == converts types before comparing, so 5 == "5" is true. === also checks the type, so 5 === "5" is false.
• Unit 4: Differentiate well-formed and valid XML. Well-formed means the syntax rules are followed. Valid means well-formed and also matching its DTD or Schema.

The BCA 105T notes solve 60 two-mark questions and 14 predict-the-output questions, and map 46 ten-mark questions to their topics across 4 units, plus 44 code examples.

These are exam-style questions for this syllabus. The notes carry no past-paper year tags, so none is labelled with a year.

BCA 105T and the BCA 105P Web Technologies lab, plus other GGSIPU BCA Sem 1 papers

The BCA 105P Web Technologies lab notes page covers the hands-on half of this paper. BCA 105P (L-P-C 0-2-2) shares the course outcomes of BCA 105T. Your teacher sets the practical list in the first week, so it differs by college.

These GGSIPU BCA Sem 1 Web Technologies notes prepare you for that lab with 40 practice tasks. Here is how each unit feeds the lab:

Other GGSIPU BCA Semester 1 papers: BCA 101T Programming for Problem Solving using C, BCA 103T Fundamental of Information Technology, BCA 107T Mathematical Foundation for Computer Science, BCA 141T Writing Skills, BCA 191T Understanding India and BCA 181T Bridge Course in Mathematics.

After this paper, the web track continues in BCA 203T Dynamic Web Designing, where PHP and MySQL build on the forms, CSS and JavaScript you learn here.
