Week 1 Summary Flashcards
The internet core is a _______ network
packet-switched
Time spent being placed on the transmission medium is called
Transmission Delay
In store-and-forward transmission, a packet switch may being transmitting the first bits of packet before it has finished receiving that the last bits of the packet.
FALSE. Stores packets until the whole thing is received and then forwards it onto the next link.
A network is a system for connecting computers using multiple, possibly different, transmission technologies.
FALSE (single transmission technology)
Time spent in transit between nodes in a network is called ______________________.
Propagation Delay
A network protocol may do the following:
Specify the whether or not information is sent
Specify the order of messages sent and received
Specify the time between sending information.
Specify the form of messages sent and received
Specify actions taken upon message transmission
Specify actions taken upon message receipt
