WEB TECHNOLOGY | UNIT-03 | ONE SHOT | PYQS AND M.IMP QUES. | BTECH | AKTU | 3RD YEAR

This video covers Unit 03 of Web Technology in one shot for B.Tech AKTU 3rd year students. It includes all the essential concepts and questions related to JavaScript, DOM manipulation, HTML forms, AJAX, comparison operators, and Java networking. The video is specially designed to help students understand every topic in a clear and concise manner for exam preparation. It explains the role of JavaScript in web pages, including how it interacts with documents, forms, statements, functions, and objects. The video also covers form handling and validation using JavaScript, demonstrating how to ensure that input fields like email are correctly validated. Further, it discusses AJAX and how to make asynchronous server requests using both XMLHttpRequest and the Fetch API, along with their advantages and limitations. The difference between == and === operators in JavaScript is also explained with examples, along with detailed coverage of JavaScript statements such as if–else, switch, and loops. The video provides a thorough explanation of DOM manipulation, including how to access elements using methods like getElementById(), getElementsByClassName(), getElementsByTagName(), querySelector(), and querySelectorAll(). It also shows how to dynamically change content, styles, and handle events such as button clicks to show or hide sections on a web page. The concept of closures in JavaScript is explained with examples, describing how inner functions can access outer variables and why closures are useful for data privacy and state preservation. In the Java networking section, the video explains the InetAddress class, how to get the local host address and hostname, and introduces the factory method design pattern using examples from the InetAddress class. It also differentiates between HTTP and TCP at the programming level, explaining their relationship with sockets and URL connections. Finally, the video covers DatagramSocket and how it differs from a TCP socket, providing example programs for sending and receiving datagrams. It also includes concepts of error handling, timeouts, and resource cleanup in Java networking, emphasizing their importance for reliability and efficiency. The session concludes with a complete explanation and example of a TCP server socket in Java that listens for a connection, reads a message, and sends a reply. This video is extremely useful for students preparing for semester exams, sessional tests, and PUTs, and serves as one of the best complete resources for understanding Unit 03 of Web Technology. unit-03 web technology unit-03 web technology aktu btech aktu unit-03 web technology unit-03 web technology aktu html xml history of web development html xml dtd web technology unit-03 one shot aktu btech 3rd year unit-03 web technology one shot unit-03 web technology one shot aktu java networking tutorial java networking in hindi java networking in hinglish tcp socket in java udp datagram socket in java datagram socket example java tcp server socket java java socket programming difference between tcp and udp java network programming explained java networking for btech aktu java networking notes java socket programming tutorial java server client program java udp example java tcp udp explained java interview questions networking java viva questions networking #pyq #webdevelopment #youtube #oneshot #webtechnology #JavaNetworking #JavaTutorial #JavaInHinglish #JavaSockets #TCPUDP #JavaProgramming #JavaInterview #DatagramSocket #ServerSocket #CodingForBeginners #AKTU #BTechCS #PlacementPrep
