A ______-switched network hasd a dedicated circuit through which information is sent
Circuit
A ____=switched entwork sends information in “Chunks” through a network on shared media
Packet
How does circuit switched networks allow multiple users to utilize a network?
Divide the resource into chunks
__divides the available bandwidth into discrete blocks of time, during which only one of the users is permitted to transmit.
TDM
_____ divides the available into bands of frequency (like radio stations), in which only one user is permitted to transmit.
FDM
the adaptive sharing of the transmission medium in packetswitched networks, based on whether or not hosts have data to transmit (on-demand), preventing the medium from being wasted by hosts without any data to transmit.
Statistical Multiplexing
What is an access network?
A network that allows a host to connect to the internet
is the rate at which bits are actually transferred between sender/receiver
