TCP-IP Layers

PreviousTCP-IP Networking ModelNextApplication Layer

Last updated 4 years ago

(like all the other models) breaks the functions into small TCP-IP Networking Layers with each layer describing a category of functions which includes Standards & Protocols.

:

  • Focuses on Bits transmission over each Link using Protocols like Ethernet, 802.11 (Wi-Fi).

:

  • Focuses on sending Data over one type of Physical Link (E.g. Ethernet, WLAN, etc.) using Protocols like Ethernet 802.3, 802.11 (Wi-Fi)

:

  • Focuses on delivering the Data from the original sending Computer to the final destination Computer using Protocols like IP & ICMP

:

  • Focuses on the Applications needed for sending & receiving the Data using Protocols like TCP & UDP.

:

  • Focuses on the Applications needed for sending & receiving the Data using Protocols like HTTP, POP3, SMTP.
