Study Notes

Web Designing (DU#2301CS202) - Unit 01

  • Introduction to Web Technology & Web Design
  • Course Instructor: Dharmik P. Vasiyani
  • Department: Computer Engineering
  • Institute: Institute of Engineering & Technology, Rajkot
  • Contact: 9924004064

What is the Internet?

  • The Internet is a massive network of networks, a networking infrastructure.
  • It connects millions of computers globally.
  • Any computer connected to the Internet can communicate with any other computer.
  • Internet communication uses a set of rules known as protocols.

What is WWW?

  • WWW stands for World Wide Web.
  • It is the collection of all resources and users on the Internet that use HTTP.
  • HTTP is a text-based request-response protocol.
  • It's an application layer protocol allowing web-based applications to communicate and exchange data.
  • HTTP is a connectionless and stateless protocol.
  • After a client makes a request, the client disconnects, and the server reconnects to deliver the response.
  • HTTP is the protocol transferring hypertext documents, enabling the World Wide Web.

How the Web Works?

  • The World Wide Web uses a client-server architecture.
  • A client (e.g., a web browser) requests a page.
  • The server (e.g., a web server software like Apache, IIS, Tomcat) processes the request and sends a response.

HTTP Request

  • An HTTP request message has a request line, header fields, an empty line, and an optional message body.
  • The request line specifies the method (e.g., GET, POST, PUT, DELETE), the resource, and the protocol version.
  • Header fields provide additional information such as the requested content type and the date of the request.

HTTP Response

  • A server responds with an HTTP response message.
  • The response includes a status line (HTTP version, status code, reason phrase).
  • Additional response headers and an optional message body (e.g., HTML content).
  • Status codes (e.g., 200 OK, 404 Not Found, 500 Server Error) indicate the result of the request.

Introduction to Web Technologies

  • HTML (HyperText Markup Language): Used for structuring web pages using markup. It defines the structure, and Hypertext defines the relationship between the pages(links).
  • CSS (Cascading Style Sheets): Used for styling web pages. It is used independently of HTML, to describe how the HTML elements should be displayed(styling).
  • JavaScript: A scripting language for creating interactive web pages and enhancing website functionality.

Bootstrap

  • A popular HTML, CSS, and JavaScript framework for developing responsive websites.
  • It's a free, download framework containing predefined choices of color, size and layout for a website.

Material Design

  • A design system by Google for building quality digital experiences (Android, iOS, Flutter, web).
  • It's inspired by the physical world.

Concepts of Effective Web Design

  • Plan the website by considering the purpose, audience, structure, and necessary elements beforehand.
  • Sketch the website on paper, determine consistent naming conventions for pages, images and files.

Web Design Issues

  • Browser & Operating Systems: Different browsers render HTML tags in different way. The same browser may exhibit differing behaviors in different operating systems.
  • Bandwidth and Cache: Connection speed affects download time. Browser 'cache' is used to store frequently accessed files to improve response time.
  • Display Resolution: Resolution varies across devices, requiring flexible design and frameworks for proper presentation.
  • Look and Feel: Design elements like site theme, typography, graphics, and navigation structure affect the website's appearance.
  • Page Layout and Linking: Website structure and linking between pages must be consistent and logical for user experience.
  • Locating Information: Web page design should facilitate easy location of information.
  • Making Design User-Centric: Design should cater to user needs (navigation, search).
  • Sitemap: A model of website for efficient navigation by users and search engines.

Planning a Website

  • Key to successful websites, planning is crucial.
  • Prioritize defining the purpose, target audience, desired outcomes, and content organization for a website.

Effective Navigation

  • Navigation should efficiently guide users through the website.
  • Clear, consistent, logical navigation enhances user experience.
  • Hyperlinks for navigation should be understandable.
  • Design considerations for effective navigation should be clear and consistent.
