    Study Notes

    What is the Internet?

    • The Internet connects hundreds of thousands of individual networks all over the world.
    • It is a type of internetwork, which is a network of networks.

    Key Components of the Internet

    • Host computers (servers) provide information as requested by client systems.
    • Machines that share information across computers are called servers.
    • Packets of information are decomposed into smaller packets for transmission.

    Internet Communication

    • The flow of packets between machines on the Internet is governed by protocols such as TCP (Transmission Control Protocol).
    • Packets of information travel across multiple networks before being reassembled at their destination.
    • The Internet uses IP (Internet Protocol) to carry data.

    Web Technologies

    • HTML (HyperText Markup Language) is the standard language for creating web pages and web applications.
    • HTML uses tags to tell the Web browser how to display the text contained in the document.
    • HTTP (HyperText Transfer Protocol) is a protocol used for transferring data, including web pages.
    • HTTPS (HyperText Transfer Protocol Secure) is a secure version of HTTP.
    • DNS (Domain Name System) software is used to translate domain names to IP addresses.
    • URL (Uniform Resource Locator) is used to locate websites and individual pages.

    Internet Service Providers (ISPs) and Web Servers

    • An Internet Service Provider (ISP) is a company that provides access to the Internet.
    • The primary function of an ISP is to connect users to the Internet.
    • A Web server is a computer that stores and serves website files.
    • When a browser requests a file, a Web server sends the requested file to the browser.

    Network Structure

    • The Internet is primarily composed of many interconnected networks.
    • The main purpose of a backbone in the Internet is to interconnect these networks.
    • Internetworking is the process of connecting separate networks, allowing them to communicate with each other.
