Across
  1. 2. (WEP) Early security algorithm for wireless networks designed to protect data.
  2. 4. Number of bits per second that can be sent from one device to another.
  3. 6. Consists of a permanent connection between two nodes.
  4. 8. Network topology in which each node on the network is connected to a single main transmission cable.
  5. 9. (MAN) Consists of a group of computers that in the same city or small geographical area but not necessarily in the same room or building.
  6. 10. (virtual private network); Uses the Internet as an extension of a LAN or other smaller network.
  7. 12. Network topology in which each node in the network carries a signal to all other nodes until the message is received at its destination.
  8. 14. Software process that encodes the file to make it unreadable unless the correct key is entered.
  9. 15. Continuous signal that can vary over an infinite range.
  10. 16. Alphanumeric code that must be entered to allow access to something.
  11. 17. Noncomputer device that attaches to a network and is given a network address.
  12. 18. Network topology in which a main node connects individually to all other nodes and the other nodes do not connect to each other.
  13. 19. Topology in which devices are added to the network at the end of the line, like the links in a chain.
  14. 22. Process of taking measurements along the analog signal to convert it into a digital signal.
  15. 25. Application or process specific software communication endpoint in a computer's operating system.
  16. 26. Wireless network connection in which a computer connects to the wireless signals transmitted by a router, which is wired to a modem.
  17. 27. Data transmission technology that creates a wired connection between computers and modems or routers.
  18. 28. Network topology used to connect smaller star topology networks via a bus topology.
  19. 32. (LAN) Consists of a group of computers and devices that are locally assembled in a limited area.
  20. 33. (WPA) Security and encryption standard for wireless data transmission.
  21. 34. (Wide area network); Consists of a group of computers within a large geographical area.
  22. 36. Radio wave-based wireless connection technology that provides communication between devices within a short range of each other, generally up to about 30 feet.
Down
  1. 1. Signal composed of discrete or segmented chunks of data.
  2. 3. Arrangement of the components of the network.
  3. 5. Piece of hardware or software that requests or accesses a service from a server.
  4. 7. (P2P) Network topology in which all devices act like both servers and clients.
  5. 11. Hardware device that provides an interface between the computer and the network; also called a network interface card (NIC).
  6. 13. Common connection point for devices in a network; simplest type of network connection.
  7. 18. Network transmission device that checks and forwards packets between parts of the network.
  8. 20. Process of verifying a user's identification.
  9. 21. Open Systems Interconnection conceptual model that separates the functions of networking into layers that keep the same functions together for
  10. 23. (GAN) Network that spans multiple countries.
  11. 24. Network topology in which computers and devices are connected to one another in a circle, or ring.
  12. 29. Technology that creates a barrier between computers.
  13. 30. LAN that is accessible to connection by roaming users.
  14. 31. (IAN)Concept for networks that connect voice and data transmissions within a cloud environment.
  15. 35. Computer connected to a network.
