Packet vs Circuit
Data is sent in fixed, reserved paths for the whole connection
What is circuit switching?
This protocol is connectionless and faster
What is UDP?
Protocol used to transfer web pages
What is HTTP?
Routing algorithm that shares info with neighbors only
What is Distance Vector?
Unique identifier for a device on a network
What is an IP address?
Data is broken into packets and can take different paths
What is packet switching?
This protocol guarantees delivery and order
What is TCP?
System that translates domain names to IP addresses
What is DNS?
Routing algorithm that knows the entire network topology
What is Link State?
Splitting a network into smaller networks
What is subnetting?
This switching type is more efficient but can cause delays
What is packet switching?
This protocol is used for streaming and gaming
What is UDP?
This reduces delay by reusing connections
What are persistent connections?
Algorithm used by OSPF
What is Link State?
Device that connects networks and forwards packets
What is a router?
This switching type guarantees bandwidth but wastes resources
What is circuit switching?
This protocol uses acknowledgements and retransmissions
What is TCP?
Time it takes for a signal to go and come back
What is RTT (Round Trip Time)?
Protocol used between different autonomous systems
What is BGP?
Technique that allows many devices to share one IP
What is NAT?
The internet primarily uses this switching method
What is packet switching?
This mechanism ensures reliable data transfer in TCP
What is error detection and retransmission (or ACKs)?
Newer protocol designed to replace TCP for web transport
What is QUIC?
Problem where routers slowly update incorrect info
What is the count-to-infinity problem?
Determines which part of an IP is network vs host
What is a subnet mask?
