Study Notes
Chapter 1: Introduction to WWW and the Internet
- The World Wide Web (WWW) or Web are pages displayed on a device when online.
- The Internet is a network of connected computers that the Web operates on. Each computer on the Internet has a unique address.
- Examples of Internet addresses include 193.138.221.215, 193.138.221.211, 193.138.221.214, 193.138.224.213, 72.14.207.104, and 72.14.207.101.
Outline
- Internet technology and the World Wide Web (WWW)
- Web application architecture.
- Server concept and Web client.
- Web Browser.
- Evolution of the Internet and Web.
- Analysis requirements and Web design.
- Scripting, outline work, and Web platform.
The History of the Internet and WWW
- ARPANET (1969): An early networking precursor to the Internet.
- Domain Name System (DNS): Developed in the 1980s, translating domain names (like example.com) to numerical IP addresses.
- First graphical Web browser: WorldWideWeb, created by Tim Berners-Lee at CERN.
- The proposal and publication of the Web: (1989-1990).
- First content-based search protocol (Gopher): Introduced in 1991.
- First widely downloaded Internet browser (Mosaic): Released in 1993.
- First webmail service (HoTMail): Launched in 1996.
- Google launched: (1998).
How the Web Works
- Client-Server architecture: Clients request services, and servers respond with the service.
The Internet Architecture
- TCP/IP: A core protocol for the internet.
- IP Address: A unique number for each computer on the network.
- DNS: Translates domain names to IP addresses.
- Internet Service: Provides access to the Internet.
- WWW: The World Wide Web.
- URL: A web address, including the protocol, domain, and path.
- HTTP: The protocol for transferring web pages.
Web Server
- Software and hardware that respond to client requests using HTTP and other protocols.
- Stores, processes, and delivers web pages.
- Examples include Microsoft IIS, Apache, Nginx, and iPlanet Web Server.
Communication Networks
- The Internet relies on physical cables (copper wires, fiber optics).
- Even wireless connections (Wi-Fi, 3G/4G/5G) use physical cables to connect to the Internet.
Communication Protocols
- A standard mechanism allowing dissimilar systems to communicate.
- Often multiple protocols are involved in a single communication.
- Common protocols include:
- TCP/IP: Controls message assembly/disassembly
- HTTP: Transfers web resources.
- FTP: Transfers files
Internet Protocol (IP) Address
- Unique identifiers for devices on a computer network.
- Public IP addresses: Assigned by ISPs, directly accessible on the internet.
- Private IP addresses: Used in local networks.
- IPv4 and IPv6: Two versions of IP addresses.
Domain Name System (DNS)
- A naming database locating and translating domain names to IP addresses.
- Relies on a collection of servers.
Uniform Resource Locator (URL)
- The address of a unique resource on the web.
- Consists of:
- Scheme (protocol)
- Authority (domain name)
- Port
- Path to file
- Parameters
- Anchor
Web Page
- A document written in HTML, viewed by web browsers.
- Stored in a specific directory of a web server.
- Contains text, graphics, videos, and hyperlinks.
Website
- A collection of related web pages containing text, images, audio, and video.
- The first page is the home page.
- Types of websites:
- Static: Fixed codes, rarely changing content.
- Dynamic: Content changes dynamically.
Web Browser
- Software that interprets and displays web pages, allowing users to interact with them.
- Translates web pages (using HTTP) into readable content.
- Displays web pages using HTML, and/or XML.
- Examples include Google Chrome, Microsoft Edge, and Opera.
Main features of Web Browsers:
- Personalization
- Search engines
- Book-marks
- Security settings
Analysis Requirements and Web Design
- Topics covered in a standard web development analysis:
- Preferred platform/technology
- Standard website layout
- Design features (like logo, fonts)
- Functionality
- Space allocation (for content)
- Header/footer layout
- Contact forms
Scripting, Outline Work, and Web Platform
- Web scripting: Process of creating and embedding scripts in web pages.
- Scripts are commands interpreted by a program (scripting engine).
- Scripts can automate tasks or dynamically generate web pages.
- Languages include VBScript, JavaScript, ASP, PHP, PERL, JSPs, and others.
Open Discussion
- Topics:
- How the Web finds a specific web page.
- Web functionality without search engines.
- Benefits of using the WWW.
