Key Terms

Review the following list of key terms:

  • bridge A connectivity device that forwards data based on physical address.

  • cut-through switching A switching method that causes the switch to start forwarding the frame as soon as it obtains the destination address.

  • dynamic routing A routing method in which routing information is supplied dynamically through routing protocols.

  • hub A connectivity device to which network cables are attached to form a network segment. Hubs typically do not filter data and instead retransmit incoming frames to all ports.

  • intelligent hub A hub capable of performing additional tasks such as blocking off a port when a line problem is detected.

  • multihomed computer A computer with multiple network adapters.

  • router A connectivity device that forwards data based on logical address (IP address, in the case of TCP/IP).

  • routing table A table within the router that relates network IDs to network paths.

  • static routing A routing method in which the routing information is input manually by the network administrator.

  • store and forward switching A switching method that causes the switch to receive the entire frame before retransmitting.

  • switch A connectivity device. A switch is aware of the address associated with each of its ports and forwards each incoming frame to the correct port. Switches can base forwarding decisions on a variety of parameters encapsulated in the headers of the protocol stack.
