- 1A wireless device that serves as the central connection point of a wireless LAN and mediates communication between wireless computers.access point (AP)
- 2A network design in which interconnecting devices allow only one connected device to transmit data at a time, thus requiring devices to share available bandwidth.bandwidth sharing
- 3The 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.broadcast domain
- 4A network message intended to be processed by all devices on a LAN; has the destination address FF:FF:FF:FF:FF:FF.broadcast frame
- 5A 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. See also access point (AP) and request to send (RTS).clear to send (CTS)
- 6A property of switches in which each port’s bandwidth is dedicated to the devices connected to the port; on a hub, each port’s bandwidth is shared between all devices connected to the hub.dedicated bandwidth
- 7The address configured in a computer’s IP address settings specifying the address of a router to which the computer can send all packets destined for other networks.default gateway
- 8A routing table entry that tells a router where to send a packet with a destination network address that can’t be found in the routing table.default route
- 9communication 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.full-duplex mode
- 10A 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.half-duplex mode
- 11A 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.hub
- 12The amount of data that can be transferred on a network during a specific interval; usually measured in bits per second. network interface card (NIC) A device that creates andnetwork bandwidth
- 13A device that creates and mediates the connection between a computer and the network medium.network interface card (NIC)
- 14An operational mode of a NIC in which all frames are read and processed rather than only broadcast and unicast frames addressed to the NIC. Protocol analyzer software sets a NIC to promiscuous mode so that all network frames can be read and analyzed.promiscuous mode
- 15A network device that takes incoming signals and regenerates, or repeats them to other parts of the network.repeater
- 16A signal used in wireless networks indicating that a computer has data ready to send on the network.request to send (RTS)
- 17A device that enables multiple 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; they have multiple interfaces, and each interface communicates with a LAN.router
- 18The name assigned to a wireless network so that wireless clients can distinguish between them when more than one is detected.service set identifier (SSID)
- 19A network device that reads the destination MAC addresses of incoming frames to determine which ports should forward the frames.switch
- 20A table containing MAC address and port pairs that a switch uses to determine which port to forward frames it receives.switching table
- 21A network message addressed to only one computer on the LAN.unicast frame
- 22A designated port on a hub or switch used to connect to another hub or switch without using a crossover cable.uplink port
