At which OSI model layers do the application layer or upper layer protocols operate?
Application Presentation Session
Do connectivity devices such as hubs and repeaters operate at the Presentation layer of the OSI Model?
No. Only protocols that users can see on their screen are considered Presentation Layer based. Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.
Which layer of the OSI model do VoIP signaling protocols operate in?

Where is HTTP on the OSI model?
HTTP would fall into either the Application layer or the Presentation layer. There are conflicting views as to which layer protocols like HTTP belong to, but it would be one of those two.
What are the devices of presentation layer?
The presentation layer in the OSI model is responsible for translating, encrypting, and compressing data for the application layer. Key devices associated with this layer include gateways and protocol converters that facilitate communication between different data formats and protocols. Additionally, software applications that handle data formatting, such as video codecs and data compression tools, also operate at this layer, ensuring that data is presented in a usable form for users or applications.
PGP work at which layer of osi model?
PGP works at the Layer 6 - Presentation level.
Where is REST on the OSI model?

Switches operate at layer and Hubs operate at layer of OSI model?
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
Which layers of the OSI reference model do not have individual protocols associated with it?
