Intro TCIP Networking Flashcards
Which protocols are TCP/IP transport layer protocols?
UDP and TCP
Which protocols are TCP/IP data-link layer protocols?
Ethernet and PPP
What are the 5 layers of the TCP/IP model?
Layer 1 - Physical
Layer 2 - Data link
Layer 3 - Network
Layer 4 - Transport
Layer 5 - Application
What does IEEE stand for?
Institute of Electrical and Electronic Engineers
What is a same layer interaction on 2 different computers?
In the TCP/IP model, 2 computers use a protocol to communicate with the same layer on another computer- protocol defines a header that communicates what each computer wants to do
What is an adjacent layer interaction on the same computer?
In the TCP/IP model, a lower layer provides a service to the layer above
What is an IP host?
Any device that has an IP that connects to a TCP/IP network
What is encapsulation?
Process of adding headers and sometimes trailers around data.
Ex. An IP packet has an Ethernet header and trailer added creating an Ethernet frame at Layer 2 so it can be sent at Layer 1 physical layer
What is a segment in TCP?
A TCP header and the data it has encapsulated at Layer 4 of the TCP/IP model
What is a packet?
A grouping of bytes including the network header and its encapsulated data at Layer 3
What is a frame?
A datalink header, trailer, and the encapsulated data in between at Layer 2 of the TCP/IP model
What is a PDU
Protocol Data Unit
Refers to the header, encapsulated data, and a trailer (if there is one) of a specific layer
