    Study Notes

    Types of Networks

    • Local Area Network (LAN) covers a small geographical area with all hardware owned by the organization using it. Usually wired with fiber optic and wireless using wifi. Computers in LAN are connected with a switch.
    • Wide Area Network (WAN) covers a large geographical area and infrastructure between LANs is leased from telecommunication companies who own and manage it. Connected with telephone lines or satellite links.

    Advantages and Disadvantages of Networks

    • Advantages include sharing files, peripherals like printers, and connections to other networks. Users can access their files from any computer on the network. Devices can connect to wired/wireless networks.
    • Disadvantages include security concerns, especially with wireless connections.

    The Internet

    • A collection of interconnected networks spanning across the world.
    • Domain Name Service (DNS) translates a domain name into an internet address.
    • Each website has a network address, like "8.8.8.8", which is difficult for users to remember, so websites use domain names like bbc.co.uk.
    • Hosting is the storing of files and data on a web server.
      • The web server is referred to as the host.
    • The Cloud is a network of servers that offer on-demand access to computing resources, including storage, applications, and services.
      • Data and programs can be accessed and used over the internet.
        • Advantages: Access anytime, anywhere, from any device, large storage capacity, automatic backup, and easy online collaboration.
        • Disadvantages: Ongoing monthly costs, bandwidth dependence on network speed, reliance on stable internet connection, less control over data.

    Web Servers, Clients, and the Cloud

    • Web servers are responsible for hosting websites, dealing with client requests, and sending web pages to browsers.
    • Clients are devices that request and receive information from web servers.
    • The cloud offers services, including storage, as well as access to applications and services.
    • The relationship between servers and clients is that a client will request a page and the server will send it to the client's web browser.

    Domain Name Service

    • DNS servers translate domain names into IP addresses.
    • When a client requests a website, the DNS server determines the server's IP address and then sends the information back to the client's browser.

    Star Network Topology

    • A star network topology consists of a central switch that all computers connect to.
    • If the switch fails, the whole network fails as no node can communicate.

    Full Mesh Network Topology

    • A full mesh network topology features a direct connection between every computer in the network.
    • Advantage: If a connection fails, traffic can be routed through another path.
    • Disadvantage: Requires a lot of cabling and switch hardware, potentially increasing costs for large networks.

    IP and MAC Addressing

    • IP Address is used to identify a host computer or node which communicates over the internet or IP.
    • MAC Address is used to route frames on a LAN.
    • IPv6 is a new version of IP addressing introduced because of increasing Internet of Things (IoT) devices which exceeded available IPv4 addresses.

    Standards and Protocols

    • Standards provide benchmarks for the quality and performance of networking components and systems.
    • Protocols are sets of rules governing communication between devices on a network.
      • HTTP (Hypertext Transfer Protocol): Client-server method for requesting and delivering HTML files.
      • HTTPS (Hypertext Transfer Protocol Secure): Encrypts and authenticates client-server data.
      • SMTP (Simple Mail Transfer Protocol): Sends mail to a mail server.
      • FTP (File Transfer Protocol): Sends files between computers and is used for uploading web pages to a web server.
      • POP (Post Office Protocol): Used by email clients to retrieve emails from a mail server.
      • IMAP (Internet Message Access Protocol): Used by email clients to retrieve and manage remote mailboxes. IMAP is more advanced and offers more features than POP.
