Please do not throw salami pizza away

Remembering the seven layers of the OSI model for communications and computer networks can be confusing. I like the humorous way of remembering the names with this memorable sentence:

  • Please
  • Do
  • Not
  • Throw
  • Salami
  • Pizza
  • Away.

The first letters map to the names of the different OSI layers:

  • Physical Layer
  • Data Link Layer
  • Network Layer
  • Transport Layer
  • Session Layer
  • Presentation Layer
  • Application Layer

This works at least for computer people enjoying salami pizza. As a sidenote, Layer 8 is not part of the standard OSI model, although it can be important for troubleshooting problems in the real world.
