chapter 3 Flashcards
Packet switching
A method of slicing digital messages into packets, sending the packets along different communication paths as they become available, and then reassembling the packets once they arrive at their destination
packets
The discrete units into which digital messages are sliced for transmission over the internet
Router
special purpose computer that interconnects the computer networks that make up the internet and routes packets to their ultimate destination as they travel the internet
Routing algorithm
Computer program that ensures that packets take the best available path towards their destination
Protocol
set of rules and standards for data transfer
ransmition control protocol/internet protocol
core communications protocol for the internet
TCP
Establishes connections among sending and receiving computers and handles assembly and reassembly of packets
iP
provides the internets addressing scheme and is responsible for delivery of packets
Network interface layer
Responsible for placing packets on and receiving them from the network medium
Internet layer
: Responsible for addressing, packaging, and routing messages on the internet
anspoer layer
Responsible for providing communication with other protocols withinTCP/IP suite
pplication layer
includes protocols used to provide user services or exchange data
order gateway protocol (BGP)
Enables exchange of routing information among systems on the internet
IPv4 Internet adress
A method of slicing digital messages into packets, sending the packets along different communication paths as they become available, and then reassembling the packets once they arrive at their destination
IPv6 internet adress
Internet adress expressed as a 128 bit number
Domain name
IP address expressed in natrual language
Domain name system
System for expressing numeric IP addresses in natural language
Uniform resource locator
The address used by a web browser to identify the location of content on the web
Client/server computing
A model of computing in which client computers are connected in netweork together with one or more servers
client
powerful desktop computer that is part of a network
server
Networked computer dedicated to common functions that the client computer on the network needs
Cloud computing
Model of computing in which computer processing, storage, software and other services are provided as a shared pool of virtualized resources over the internet
