Communication protocols are like envelopes. An envelope provides a service to its contents. Each envelope represents some encapsulation of data which is necessary for communication between “layers” of the OSI model. Each envelope includes information about its contents, destination, and handling instructions. As data is passed from place to place it is encapsulated inside several envelopes so that it can be transferred over different mediums.
