Ethernet started with a bus topology. Computers in Ethernet use
shared media and therefore need an access control system to allow
them to share this media. Which system does Ethernet use for access
control of shared media? Answer: Carrier Sense Multiple Access
Collision Detection (CSMA/CD)
Legacy networks contained hubs and bridges. Most modern networks
use switches and routers but not hubs and bridges. Why have bridges
been removed from modern networks? Answer: Bridges were phased
out because they are not needed to divide collision domains in modern
networks; switches perform this task.
Computer networks provide critical functions for organizations. This
means that network resiliency is very important. How can a network
architect build resiliency into a network? Answer: Running servers
with dual Network Interface Cards (NIC) can provide resiliency.
Connection-oriented Answer: Normal discussion between two people
User Datagram Protocol (UDP) Answer: Connectionless
Transmission Control Protocol (TCP) Answer: Connection-oriented
Internet Protocol (IP) Answer: Connectionless
