Across
  1. 4. A private network that looks and functions a lot like the Internet but is typically available only to the employees of an organization.
  2. 5. What an organization’s intranet becomes when the organization allows outsiders to access its intranet.
  3. 7. computer intended to be used by one person at a time.
  4. 10. A card that enables one computer to send and receive data to and from another computer.
  5. 12. Data transmission that uses radio frequencies instead of cabling.
  6. 16. A type of hub that uses a table to keep track of destinations so that data can be sent directly to its destination, rather than to every computer on the network before the destination machine receives it.
  7. 17. Any receiving point in a computer network.
  8. 18. Two or more devices connected together.
  9. 21. Often called a network switch, this connects many parts of a network and directs traffic as needed.
  10. 22. The rules of initiating, interrupting, and continuing communication on a computer network.
  11. 24. A central point on a network where computers can connect. The central point is often a switch rather than a hub.
  12. 26. A LAN topology wherein two star networks are linked using a bus.
  13. 28. The study of how items are related to one another in space; a configuration.
  14. 30. The primary networking technology currently in use. Ethernet defines standards for addressing packets and data and a method for avoiding data conflicts on the network.
Down
  1. 1. A device that links two computer networks or links a local area network to the Internet. A router reads packet addresses and routes packets.
  2. 2. The most commonly used kind of networking cable today.
  3. 3. A network architecture where all computers have equal responsibilities and all computers can share files with each other.
  4. 6. A topology with one central node that has each computer or network device attached to the central node. All data first goes into the central node and then is sent out to its destination. (Think of it like a bicycle wheel with spokes.)
  5. 8. A person who manages a computer network; he or she designed its topology and adjusts it as needed to suit the organization’s needs.
  6. 9. A piece of hardware or software on a network designed to limit access to certain machines to authorized users only.
  7. 10. A set of programs used to manage and secure a network.
  8. 11. A network layout in which each individual node is connected to two others, with the first and last coming back to connect to each other, thus completing the ring shape.
  9. 12. A type of network where the computers are far apart—in different buildings, different cities, or even different countries.
  10. 13. A type of network where computers are close together, typically in the same building or office.
  11. 14. network architecture in which each computer is either a client or a server. Servers are powerful computers dedicated to managing the clients. Clients are PCs on which users run applications. Clients rely on servers for resources..
  12. 15. The design of a computer network, which specifies how devices communicate with one another. The most common network architecture types are client/server and peer-to-peer.
  13. 19. A network layout in which there is one main trunk, or backbone, that all the various computers and network devices are connected to.
  14. 20. Cable that uses light guided through thin glass tubes, instead of electrical signals, to transmit data. It is very fast but also expensive.
  15. 23. The small unit into which information is broken down before being sent across a network.
  16. 25. A type of electrical cable often used to transmit cable TV.
  17. 27. The central core of a network, this connection can link many smaller networks to a larger network.
  18. 29. A computer dedicated to providing one service (such as web hosting, disk storage, and so on) and that is shared by many users across a network.
