Study Notes

Introduction to the Internet and the World Wide Web

  • The Internet is a global network of interconnected devices and computers.
  • With the Internet, users can access almost any information, communicate with anyone in the world, and do much more.
  • A network is a group of two or more computer systems connected through channels to send and receive data.
  • The World Wide Web (WWW) is a collection of websites accessible through the Internet.
  • WWW is part of the Internet, not synonymous with it.
  • Websites are made up of related text, images, and other resources, often resembling media like articles or programs, or being interactive.
  • Web pages are the fundamental components of the WWW, linked via hyperlinks or hypertext.
  • Hyperlinks allow users to move from one specific spot in a hypertext or hypermedia document to another or a different document entirely.
  • Hypertext enables instant information cross-referencing across web pages.

Internet Protocols and Technologies

  • Domain names: Strings that identify a realm of administrative autonomy or control; often used to identify internet services like websites and emails
    • Include top-level domains (TLDs), and second-level domains (SLDs)
  • Data transmission rules are defined by protocols.
  • The most important Internet protocol is TCP/IP: Transmission Control Protocol / Internet Protocol which facilitates communication between computers (clients and servers).
  • Client computers request data from servers.
  • Servers respond to client requests.
  • Servers contain data and protocols to ensure smooth operation.

Protocols

  • HTTP (Hypertext Transfer Protocol): A protocol that enables web browsers and web servers to communicate, which defines how data is transferred across the web.
  • HTTPS (Hypertext Transfer Protocol Secure): A secure version of HTTP with encryption, ensuring secure communication for data privacy during transmission.
  • FTP (File Transfer Protocol): A protocol used to transfer computer files between a server and a client.

Client & Server Interaction Basics

  • The client and server interact.
  • Clients request data from servers.
  • The client doesn’t hold all data
  • Servers hold data and provide it to clients.

Specific Protocols

  • SMTP (Simple Mail Transfer Protocol): Email transmission protocol
  • POP3 (Post Office Protocol version 3): Email retrieval protocol
  • IMAP (Internet Message Access Protocol): Another email retrieval protocol
  • VoIP or Voice over Internet Protocol (VoIP): Allows voice calls via a broadband internet connection rather than a physical phone line.

Domain Name System

  • The Domain Name System (DNS) converts domain names into IP addresses that computers use to locate websites.
  • A DNS server stores the mappings between domain names and IP addresses.
