    Study Notes

    The Internet and the World Wide Web

    • Internet connects billions of computers globally, using TCP/IP protocols.
    • The internet uses various technologies, including optical fibers and wireless connections (3G, 4G, Wi-Fi).
    • The internet is a network of networks, connecting computers and servers across the world, through routers, switches, and communication channels.
    • It was developed by DARPA (Defense Advanced Projects Agency) in the USA, starting in 1969.

    How the Internet Works

    • The internet operates using clients and servers.
    • A client (e.g., laptop) connects to the internet through an Internet Service Provider (ISP).
    • Each device is identified by an IP address provided by the ISP.
    • Servers store websites and respond to client requests.
    • Data travels through optical fibres, converting light signals to electrical signals to reach client devices.
    • Data transfer is fast because it is transmitted in binary form (0s and 1s) in packets.
    • Domain names (e.g., youtube.com) are easier for users to remember than IP addresses and are translated by DNS servers.

    Intranet

    • A private network within an organization.
    • Designed for internal use (employees, associates).
    • Secure platform for sharing information and data, with only authorized users having access.
    • Can be used for internal communications, announcements, company documents, and applications.
    • More secure than the internet.
    • Usually cheaper and easier to implement.
    • Intranets use web servers, platforms, and applications.

    Extranet

    • An extension of a company's intranet.
    • Provides controlled access to specific external resources (customers, suppliers, partners).
    • Securely shares internal information with external parties (trading partners, customers, etc.)
    • Uses internet protocols, especially VPN connections.
    • This allows secure access to information.

    Advantages and Disadvantages of the Internet/Intranet/Extranet

    • Internet:*
    • Advantages: Instant messaging, online shopping, online banking, etc.
    • Disadvantages: Less secure, need an internet connection, possible security risks.
    • Intranet:*
    • Advantages: Secure, internal communication, information sharing amongst authorized users.
    • Disadvantages: Limited to the organization's internal network, more challenging to share information beyond the organization.
    • Extranet:*
    • Advantages: Secure access to external parties or customers, sharing information with strategic partners.
    • Disadvantages: Security vulnerabilities.
