Across
- 4. A network device that takes incoming signals and regenerates, or repeats, them to other parts of the network.
- 7. A network device that performs the same function as a repeater but has several ports to connect a number of devices; sometimes called a multiport repeater.
- 8. A communication mode in which a device can send or receive data but can’t do both simultaneously. Hubs operate only in half-duplex mode; switches can operate in both half-duplex and full-duplex modes.
- 10. Service set identifier. The name assigned to a wireless network that is configured on the wireless access point.
- 12. ________ gateway. The address configured in a computer’s IP address settings specifying the address of a router to which the computer can send packets addressed to devices on other networks.
- 13. Access point. A wireless device that serves as the central connection point of a wireless LAN and mediates communication between wireless computers.
- 14. A network device used to interconnect multiple computers; it reads the destination MAC address of an incoming frame to determine on which switch port the destination device is located.
- 17. ________ frame. A network message addressed to only one computer on the LAN.
- 18. Bandwidth ________. A network design in which interconnecting devices allow only one connected device to transmit data at a time, thus requiring devices to share available bandwidth.
- 20. A designated port on a hub or switch used to connect to another hub or switch without using a crossover cable.
Down
- 1. A device that enables LANs to communicate with one another by forwarding packets from one LAN to another. Routers also forward packets from one router to another when LANs are separated by multiple routers.
- 2. Broadcast ________. A network message intended to be processed by all devices on a LAN; it has the destination address FF:FF:FF:FF:FF:FF.
- 3. Network ________.The amount of data that can be transferred on a network during a specific interval; usually measured in bits per second.
- 5. A communication mode in which a device can simultaneously transmit and receive data on the same cable connection. Switches can operate in full-duplex mode, but hubs can’t.
- 6. _________ bandwidth. A property of switches in which each port’s bandwidth is dedicated to the devices connected to the port.
- 9. Making a connection between devices such as two switches, usually for the purpose of expanding a network.
- 11. Request to send. A signal used in wireless networks indicating that a computer has data ready to send on the network.
- 15. Broadcast ________. The scope of devices to which broadcast frames are forwarded. Router interfaces delimit broadcast domains because they don’t forward broadcasts, whereas switches and hubs do.
- 16. Clear to send. A signal an AP generates in response to a request-to-send signal. A CTS signal indicates that the computer that sent an RTS can transmit data.
- 19. Network Interface Card. A device that creates and mediates the connection between a computer and the network medium.
