C1. Networking Fundamentals Flashcards
What is a workstation?
It’s a seriously powerful computer with more than one CPU whose resources are available for other computers if and when needed
What is the difference between a workstation and a client?
Client machines typically ask for access to resources from a server or a powerful workstation
What is a server?
A cool computer with a superior CPU(s..), hard drive space, and memory
What is a host?
It’s a network device with some IP addresses
What are the two kinds of network topologies
Physical and logical
Define bus topology
It’s a physical network topology where all computers on the network see all the data that’s flowing through a cable; only one computer - to which data is addressed - actually gets it
What are the advantages of bus topology?
1) Easy to install
2) Not very expensive
Disadvantages of bus topology
1) Hard to troubleshoot, change, or move
2) Little fault tolerance - if central cable fails so does everything else
Define Star Topology
It’s a physical (??) WAN topology where all computers are connected to a central point with individual cables or wireless connections
What are the benefits of star topology?
1) If one cable fails, it only brings down the machine or network segments related to the point of failure
2) Scalability
3) Easy to troubleshoot
What is a device at the center of the star topology network?
It’s a hub/switch
What are the drawbacks of the star topology?
1) If the circuit hub fails, everything else does
2) There’s a high total installation cost due to the number of cables
Name two extensions of the ring topology
Wireless and point-to-point
Define the Ring topology
In the ring topology, each computer is directly connected to other computers within the same network
What are the advantages of ring topology?
1) Cable faults are easily located, making troubleshooting easier.
2) Ring networks are moderately easy to install.
