Cheat Sheet

  1. Internet Origins: ARPANET & Beyond -

    Trace the internet's evolution from the ARPANET research network launched in 1969 to the global Internet after TCP/IP standardization in 1983. A handy mnemonic is "A Really Powerful Academic Network" to remember ARPANET's role. Reputable sources include UCLA's ARPANET historical archives and the Internet Society.

  2. Core Protocols: TCP/IP & HTTP(S) -

    Master TCP/IP's four layers - Link, Internet, Transport, Application - using the mnemonic "LITA" to keep them in order. Review HTTP methods like GET and POST (e.g. GET /index.html HTTP/1.1) and how HTTPS adds SSL/TLS encryption as documented in IETF RFC 2616 and RFC 5246. These standards are published by the IETF and W3C.

  3. Web Development Essentials: HTML, CSS & JavaScript -

    Understand HTML's role in structuring web content (e.g., <h1>Title</h1>), CSS for styling (e.g., body {color: blue;}), and JavaScript for interactivity. The W3C and ECMA International provide official specifications, so reference HTML5, CSS3, and ECMAScript docs. A quick tip is "HTML builds, CSS styles, JS adds life" to recall each layer's function.

  4. Internet Safety: SSL/TLS & Best Practices -

    Remember that a padlock icon in your browser bar indicates SSL/TLS encryption securing data in transit, as defined by the IETF. Use strong passwords (12+ characters with mixed types) and enable two-factor authentication to guard accounts. Official guidance from NIST and OWASP offers best practices against phishing and common web threats.

  5. Domain Name System: How DNS Works -

    Learn how DNS resolves domain names to IP addresses via A, AAAA and CNAME records, as outlined by ICANN and the IETF's DNS RFCs (e.g., RFC 1035). Test your understanding by using tools like nslookup or dig (e.g., dig example.com A). A simple memory aid is "DNS = Dials Names to Servers" to recall its lookup function.
