2.1 Introduction to IP Flashcards
In terms of the Internet, what represents a shipping truck, the road, and what type of shipping truck it is?
Shipping truck - large amounts of data being moved
Road - network topology (Ethernet, DSL, cable system)
Shipping truck - roads were designed for the Internet Protocol (IP) truck
What represents what’s inside the boxes holding your data?
Boxes of TCP and UDP
What else is inside the boxes holding your data?
Application information, etc
How is TCP and UDP transported?
inside of IP
TCP and UDP are encapsulated by what?
the IP protocol
What are TCP and UDP different ways for?
2 different ways to move data from place to place
(different applications have/need different features)
TCP and UDP are located in what OSI layer?
Layer 4
What is multiplexing in terms of TCP and UDP?
use many different applications at the same time
What type of connection is TCP?
connection-oriented
(formal connection, waits for acknowledgment)
Which connection method can manage out-of-order messages and retransmissions?
TCP
(provides recovery from errors)
What type of connection is UDP?
connection-less
(no formal open/close to the connection)
Which connection is reliable delivery and which is unreliable delivery? (2)
reliable delivery - TCP
unreliable delivery - UDP
Both UDP and TCP have error recovery and can reorder data/retransmissions. T or F?
False, only TCP has error recovery and reorders data/retransmissions
Which connection doesn’t stop and allow you to re-send the data?
UDP (provides real-time communication)
What are 2 connectionless protocols that would use UDP?
- DHCP
- TFTP (Trivial File Transfer Protocol)
