Q

what is a

protocol model

A

this is a model that describes and closely matches the structure of a particular protocol suite.

example

The TCP/IP model is this because it describes all the functions that exist within the TCP/IP suite

Q

what is a

reference model

A

this is a model that describes how a function at a given level should operate but does not give any detail of how that should be implemented.

The benefit of a this is to provide clearer understanding of the layers needed and there functions in order to achieve network communication.

Q

what actions take place when an ethernet frame reaches the destination P.C

A

When a pc receives an ethernet frame the Network Interface Card (NIC) will look at the destination address and determine if it was in fact addressed to them if it is then the rest of the frame will be read otherwise the ethernet frame will be discarded in essence the pc never receives the message
