@rohitkumar-es5uc Год назад

I have a doubt here, whether Ssl/TLS is part of application layer, or it should be at Presentation or Session layer ?

@abdchuhan 5 месяцев назад

I always wonder why we have network layer above than data link layer i.e. order-wise request from Host first reaches to the Switch rather than Router… Anyone have answer for it, kindly respond.

it would be great if it had a translation in Spanish, thanks a lot.

Please (Physical Layer) Do (Data Link Layer) Not (Network Layer) Tell (Transport Layer) secret (Session Layer) Password (Presentation Layer) Anyone ( Application Layer )

@mantid83 Год назад

This one works for me the best. Please (Physical Layer) Do (Data Link Layer) Not (Network Layer) Teach (Transport Layer) students (Session Layer) Phony (Presentation Layer) acronyms ( Application Layer )
