CS38 : The TCP/IP Stack

All exam boards apart from iGCSE require a detailed knowledge of the operation of the TCP/IP protocol stack which enables consistent communication across the Internet (and beyond ...)

We are learning ...
  • About the functions of the main networking protocols
  • About the operation of and the functions of the layers in the TCP/IP stack.
So that we can ...
  • Define the term 'network protocol'
  • Explain the purpose of common networking protocols ...
    - Ethernet
    - WiFi
    - TCP (Transmission control protocol)
    - UDP (User datagram protocol)
    - IP (Internet protocol)
    - HTTP (Hypertext Transfer Protocol)
    - HTTPS (Hypertext Transfer Protocol Secure)
    - FTP (File transfer protocol)
    - SMTP (Simple mail transfer protocol)
    - IMAP (Internet Message Access Protocol)
    - POP3 (Post Office Protocol)
  • Describe the functions of the 4 layers in the TCP/IP Stack
    - Application layer (HTTP / HTTPS / SMTP / IMAP / FTP)
    - Transport layer (TCP / UDP)
    - Network layer (IP)
    - Data link layer (MAC)
  • Packet switching (OCR)
