- 4. A software technology that enables you to run multiple virtual operating systems and applications on a single physical computer.
- 7. Technologies that consist of various methods for radio transmission in which frequencies or signal patterns are continuously changed.
- 8. The LAN access method used by Ethernet. Checks for network access availability with a signal.
- 10. A large set of frequencies capable of carrying data at higher rates (for example, 1.544 Mbps). It carries digital signals and includes DSL and cable Internetaccess.
- 12. A logical opening in an operating system or protocol stack that allows the transfer of information. Not the same as a TCP or UDP port.
- 14. A base-16 number system that allows large numbers to be displayed by fewer characters than if the number were displayed in the regular base-10 system.
- 15. A device that connects networks.
- 16. The weakening of a transmission signal as it travels farther from its source.
Down
- 1. The hardware address of a device connected to a network.
- 2. A device that transmits and receives digital or analog signals.
- 3. Logical subgroup within a LAN created with software instead of hardware.
- 5. A device that provides connectivity between at least two systems.
- 6. A measurement of memory needed to store one 8-bit character.
- 9. Space between building floors; usually contains air and heating ducts, as well as communication and electrical wires.
- 11. A device that forwards traffic based on MAC addresses.
- 13. High-capacity two-wire (signal and ground) cable; the inner wire is the primary conductor, and the metal sheath serves as the ground.
- 14. A device used to connect systems so that they can communicate with one another.
