  1. 1. (Abbreviation only.) A layered network architecture model of communication developed by the International Organization for Standardization (ISO). Defines seven layers of network functions.
  2. 5. Any material that allows data to flow through it or be stored on it; includes hard and floppy disks, wire, cable, and fiber optics.
  3. 7. A point in network communication at which information is processed more slowly. Also, any element (a hard drive, I/O card or network interface card) that slows network connectivity rates.
  4. 14. An individual computer connected to a network. Also, a system or application (such as a Web browser or user agent) that requests a service from another computer (the server) and is used to access files or documents.
  5. 15. A circuit board within a computer's central processing unit that serves as the interface enabling the computer to connect to a network.
  6. 16. An operating system that manages network resources.
  7. 18. The ability for a device to automatically track and report the user's location and availability.
  8. 19. A computer that other computers can use to gain information; in network architecture, a host is a client or workstation.
  9. 21. An organization that maintains a gateway to the Internet and rents access to customers on a per-use or subscription basis.
  10. 22. The coding necessary to create relationships in the data stored in a database.
  11. 23. (Abbreviation only.)A technology that converts voice into data packets for transmission over a packet-switched IP network. It allows the use of the Internet for real-time voice and video traffic.
  12. 25. A group of computers connected over an expansive geographic area so their users can share files and services.
  13. 27. A group of computers connected within a confined geographic area.
  14. 30. A device that routes packets between networks based on network-layer addresses; determines the best path across a network. Also used to connect separate LANs to form a WAN.
  15. 32. The forms in which the data and business logic are presented on your screen. Presentation responsibilities include HTML forms and application-specific interfaces such as Web browsers.
  16. 33. A model that, because of its age, may not support modern technologies without manipulation or upgrades.
Down
  1. 2. Part of a larger structure; a common term used in networking.
  2. 3. Information being stored, usually in a database.
  3. 4. A command-based interface that allows a user to issue commands.
  4. 6. A business trend that seeks to simplify and integrate all forms of communication. Also, a set of technologies that enable voice to be converted into text, and vice versa.
  5. 8. The LAN access method used by Token Ring networks. A data frame, or token, is passed from one node to the next around the network ring.
  6. 9. Software, infrastructure, and platform services that are hosted by a remote data center and provided to organizations or individuals over the Internet.
  7. 10. A peer-to-peer file sharing protocol used for distributing large amounts of data.
  8. 11. The highest level in the computer network hierarchy, to which smaller networks typically connect.
  9. 12. A device that contains a battery to provide power during a power outage.
