Q1.Explains what is WWW, internet, client, server, client-server architecture, working of web and the common web terminologies such as URL, HTTP, MIME Summary of Web ? • WWW: The World Wide Web (WWW) is a system of interlinked hypertext documents accessed via the internet. It allows users to view and navigate web pages using browsers. • Internet: A global network of interconnected computers that communicate using standardized protocols. It enables data exchange and resource sharing among millions of devices worldwide. • Client: A client is a device or software that requests services or resources from a server. Examples include web browsers, email clients, and mobile apps. • Server: A server is a computer or software that provides services or resources to clients. It hosts websites, manages databases, and handles requests from clients. • Client-Server Architecture: A computing model where clients request services and servers provide them. It enables efficient resource management and centralized control. • Working of Web: The web operates on a client-server model. Clients send requests to servers using URLs. Servers process these requests and send back the requested resources. • URL: Uniform Resource Locator (URL) is the address used to access resources on the web. It specifies the protocol, domain, and path to the resource. • HTTP: Hypertext Transfer Protocol (HTTP) is the protocol used for transferring web pages and resources over the internet. It defines how messages are formatted and transmitted. • MIME: Multipurpose Internet Mail Extensions (MIME) is a standard that extends the format of email to support text in character sets other than ASCII, as well as attachments like images and documents.thumbs_up_downmore_vertnorthrefreshkeyboard_arrow_downmicsend
Web technologies encompass a broad range of tools and techniques used to create and manage websites and web applications. These technologies can be broadly categorized into front-end, back-end, and full-stack development. Each category plays a crucial role in the overall functionality and user experience of web applications.
Front-end development focuses on the client side of web applications, which is what users interact with directly in their web browsers. The main technologies used in front-end development include:
Purpose: Provides the structure of web pages.
Significance: HTML is the backbone of any web page. It defines elements such as headings, paragraphs, links, images, and other types of content. Without HTML, web pages would lack structure and organization.
Example:
<h1>Welcome to My Website</h1><p>This is a paragraph of text on my website.</p>
Purpose: Adds styling to web pages.
Significance: CSS is used to control the presentation of HTML elements, including layout, colors, fonts, and overall visual aesthetics. It allows developers to create visually appealing and responsive designs.
Example:
body { background-color: lightblue;}h1 { color: navy; text-align: center;}
Purpose: Adds interactivity and dynamic content to web pages.
Significance: JavaScript enables the creation of interactive elements such as forms, animations, and real-time updates. It enhances user experience by allowing web pages to respond to user actions without needing to reload.
Example:
document.getElementById("myButton").onclick = function() { alert("Button clicked!");};
