Which of the following layers of the OSI model corresponds to the Host-to-Host layer of the TCP/IP
model?
A.
The transport layer
B.
The presentation layer
C.
The session layer
D.
The application layer
Explanation:
The transport layer of the OSI model corresponds to the Host-to-Host layer of the
TCP/IP model. The transport layer defines how to address
the physical locations and devices on the network, how to make connections between nodes, and it
also handles the internetworking of
messages.
The TCP/IP model is a specification for computer network protocols created by DARPA, an agency of
the United States Department of Defense.
It laid the foundation for ARPANET, which was the world’s first wide area network and a predecessor
of the Internet. The TCP/IP Model is
sometimes called the Internet Reference Model, the DoD Model or the ARPANET Reference Model.
Answer options C, D, and B are incorrect. The presentation, application, and session layers of the
OSI model correspond to the application
layer of the TCP/IP model.
The OSI model organizes network communication through seven different layers. Each layer has a
group of protocols associated with it.
Protocols can be defined as rules that every computer should follow in order to communicate within
a network. A protocol stack is formed
when a communication needs more than one protocol to complete the process. The commonly used
protocol stack is TCP/IP, which is used for
communication over the Internet.
