Across
- 1. (Abbreviation only.) A layered network architecture model of communication developed by the International Organization for Standardization (ISO). Defines seven layers of network functions.
- 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.
- 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.
- 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.
- 15. A circuit board within a computer's central processing unit that serves as the interface enabling the computer to connect to a network.
- 16. An operating system that manages network resources.
- 18. The ability for a device to automatically track and report the user's location and availability.
- 19. A computer that other computers can use to gain information; in network architecture, a host is a client or workstation.
- 21. An organization that maintains a gateway to the Internet and rents access to customers on a per-use or subscription basis.
- 22. The coding necessary to create relationships in the data stored in a database.
- 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.
- 25. A group of computers connected over an expansive geographic area so their users can share files and services.
- 27. A group of computers connected within a confined geographic area.
- 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.
- 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.
- 33. A model that, because of its age, may not support modern technologies without manipulation or upgrades.
Down
- 2. Part of a larger structure; a common term used in networking.
- 3. Information being stored, usually in a database.
- 4. A command-based interface that allows a user to issue commands.
- 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.
- 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.
- 9. Software, infrastructure, and platform services that are hosted by a remote data center and provided to organizations or individuals over the Internet.
- 10. A peer-to-peer file sharing protocol used for distributing large amounts of data.
- 11. The highest level in the computer network hierarchy, to which smaller networks typically connect.
- 12. A device that contains a battery to provide power during a power outage.
- 13. Any entity on a network that can be managed, such as a system, repeater, router, gateway, switch or firewall. A computer or other addressable device attached to a network; a host.
- 17. An open-source software platform that allows the storage, processing, and analysis of massive amounts of unstructured data; used primarily for cloud applications.
- 20. The essential part of an operating system; provides basic services; always resides in memory.
- 24. The ability of one computer system to communicate with another; often refers to different operating systems working together.
- 26. (Include the dash)A series of systems that fulfill requests made by a client. Back-end systems can include mainframes and servers containing information databases.
- 28. A computer in a network that manages the network resources and provides, or serves, information to clients.
- 29. (Include the dash)A client that acts as an interface to a collection of servers (for example, mainframes or PC-based servers). A Web browser is a typical front-end client.
- 31. (Include the period.)A windowing system used with UNIX and all popular operating systems.
