CH 2: Network Design Essentials
Show Answers:

  1. The central device through which signals pass in a wireless network.
    Access Point (AP)
  2. Network devices that regenerate received signals and send them along the network.
    Active Hubs
  3. A network topology in which computers are responsible for sending data along a netowrk.
    Active Topology
  4. A wireless communication scheme by which devices communicate directly with one another without using a central hub.
    Ad Hoc Topology
  5. A single cable segment used in a bus topology to connect computers in a straight line.
  6. A network topology in which the computers connect to a backbone cable segment to form a straight line.
  7. Devices are connected in a star. A central device sits in the middle and other swithces are connected to the central switch's ports. Computers are then attached to these swithces or hubs, forming additional stars. Sometimes referred to as a hierarchial star topology.
    Extended Star
  8. The central point of connection of a star network.
  9. The mode of wireless communication in which wireless devices are configured to use an access point.
    Infrastructure Mode
  10. The path that the data travels between computers on a network.
    Logical Topology
  11. A hybrid network in which all computers connect to eachother; this topology is used for fault tolerance.
  12. A central connection point through which signals pass without regeneration.
    Passive Hub
  13. A network topology in which computers listen to the data signals being sent but do not participate in network communications.
    Passive Topology
  14. The arrangement of the cabling that interconnects network devices.
    Physical Topology
  15. A network topology consisting of computers connected in a circle, forming a closed ring.
  16. A phenomenon that occurs when a bus is not terminated and signals continue to traverse the network.
    Signal Bounce
  17. Signals traveling across a medium until they weaken or are absorbed.
    Signal Propagation
  18. A network topology in which computers connect through a central connecting point, usually a hub.
  19. A special device that manages connections between any pair of star-wired devices on a network.
  20. A hardware device used to absorb signals as they reach the end of a bus, thus freeing the network for new communications.
  21. A small data packet used in some ring topology networks to ensure fair communications between all computers.
  22. A method of passing data around a ring network.
    Token Passing
  23. The basic physical layout of a network and the way in which network components communicate with each other.
