What are the 7 layers of the OSI model?
Physical, Data Link, Network, Transport, Session, Presentation, Application
What layer of the OSI model is responsible for network applications (like HTTP or FTP) and their production of data to be transferred over the network?
Application layer
What layer of the OSI model is responsible for translating data from the application layer into the format required to transmit the data over the network as well as encrypting the data for security if encryption is used?
Presentation layer
What layer of the OSI model is responsible for connection establishment, session maintenance, and authentication?
Session layer
What layer of the OSI model provides services to the application layer and receives services from the network layer and is responsible for the reliable delivery of data and is often called the heart of OSI?
Transport layer
What layer of the OSI model is responsible for the transmission of data between hosts in different networks as well as routing of data packets?
Network layer
What layer of the OSI model is responsible for the delivery of data to the receiving device or node?
Data Link layer
What layer of the OSI model is responsible for physical connections of the devices in the network?
Physical layer
What are the layers of the TCP/IP model?
Application, Transport (host-to-host), Internet (internetworking), Network interface (link, physical, network access)
What is the TCP/IP layer that includes the Transmission Control Protocol (TCP)?
Transport
Which OSI layer is responsible for breaking data into packets?
Transport
Which layer of the OSI reference model includes all computer programs that interact with the network?
Application
What is the OSI layer that includes IPX?
Network
What is the OSI model that is responsible for logical addressing?
