So Many Protocols, So Many Layers

With seven layers and more than 50 protocols, it may seem
daunting to remember the layer in which each protocol resides.

One way to learn this is to create flash cards. On the front of each
card, write the name of the protocol; then on the back, write the
layer name. After shuffling the cards, put the card for each protocol
in a pile representing its supposed layer. Once you have placed all
the protocols, check your work by viewing the backs of the cards.
Repeat this process until you are able to place each one correctly.

Application Layer

The Application layer (layer 7) is responsible for interfacing user
applications, network services, or the operating system with the

protocol stack. It allows applications to communicate with the
protocol stack. The Application layer determines whether a remote
communication partner is available and accessible. It also ensures that
sufficient resources are available to support the requested
communications.

The application is not located within this layer; rather, the protocols
and services required to transmit files, exchange messages, connect to
