  1. 1

    A network transmission device that connects nodes in a star topology, regenerating, retiming, and amplifying the data signal each time it passes through the hub.

  2. 2

    Communications that occur in discrete units, in which the start of a unit is signaled by a start bit at the front, and a stop bit at the back signals the end of the unit.

  3. 3

    Data transmission rate used to describe older modem speed measurements, in which one data bit is sent per each signal oscillation.

  4. 4

    The number of binary bits (0s or 1s) sent in one second.

  5. 5

    A network transmission device that connects different LANs or LAN segments using the same access method. An example is connecting one Ethernet LAN to another Ethernet LAN.

  6. 6

    Saturation of network bandwidth by excessive traffic, as when a large number of computers or devices attempt to transmit simultaneously, or when computers or devices persist in transmitting repeatedly

  7. 7

    A digital modem device designed for use with the cable TV system, providing high-speed data transfer.

  8. 8

    Two network segments connected by one or more repeaters; or the network segments between two or more Layer 2 devices, such as switches or bridges.

  9. 9

    A device that can have multiple inputs and outputs all active at the same time.

  10. 10

    A technology that uses advanced modulation technologies on existing telecommunications networks for high-speed networking between a subscriber and a telco.

  11. 11

    A routing process in which the router constantly checks the network configuration, automatically updates routing tables, and makes its own decisions about how to route packets.

  12. 12

    Software or hardware that secures data from being accessed outside a network and that can also prevent data from leaving the network through an inside source.

  13. 13

    When a network device, such as a bridge, retransmits a frame or packet to all of its outgoing ports.

  14. 14

    A network device that enables communications between two different types of networked systems, for example, between complex protocols or between different email systems.

  15. 15

    The movement of a frame or packet, point to point, from one network to the next.
