Network Concepts Flashcards
You are comparing the TCP/IP model and the OSI model. What layers of the OSI model are similar to the network interface layer of the tcp/ip model?
The physical and data link of the OSI model. The network interface is sometimes called the Link layer
What is Layer 2 of the OSI Model?
Data link. OSI is an acronym for Open Systems Interconnection
Which layers of the OSI model is/are directly related to the Application layer of the tcp/ip model
5,6,7 ( the session, presentation and application) of the OSI model
Layer 1and 2 (physical layer and data link ) of the OSI compares to what level of the Tcp/ip model
The network interface or (link layer)
Identify the correct layer for routers.
Network
At which layer does data compression take place?
Presentation

Virtualization
Arrange the layers of the TCP/IP Internet model in the correct order.
Application–ftp,TFTP, DNS, VoIP, ssh, telnet
Transport–TCP and UDP
Internet–IPv4, IPv6 ICMP, IGMP
Link–ARP
