Learning Unit 6 - Telecommunications

3. A network entity/ device/ computer/ software that converts data between incompatible systems.
4. A type of switching in which messages are divided into smaller units called packets containing all source and destination addresses needed to traverse the network.
7. It is a place of convergence where data arrives from one or more directions and is forwarded out in one or more directions.
8. An adapter that interfaces a computer/ device to a network.
16. Electronic transmission of signals for communications.
17. A device or software that determines the next network point to which data should be forwarded.
19. Communications processors that allow a single communication channel to carry data transmissions from many terminals simultaneously (at the same time).
21. Signals that consist of short pulses.
22. A topology in which each computer (node) on the network connects to the other, creating a point-to-point between every network device.
23. A communication mode in which the receiver gets the message later than when it was originally sent.
24. ______ are connected to a network and is used typically by a single person or individual.
27. Using computer networks to link people and resources.
28. An internet work processor that connects two or more networks that use the same communications protocol.

1. A device that connects all segments of a network together.
2. A communication mode in which the receiver gets the message instantaneously.
5. Two or more computers that are connected in order to share data/ information, peripherals, etc.
6. The capacity of a channel.
9. A type of switching in which the source and destination computers create a single and dedicated path between the devices for the period of the connection.
10. Process by which information is made available to others..
11. ______ have no processing or memory capabilities.
12. A transmission mode in which transmission is possible in both directions over a channel simultaneously.
13. Signals that are continuous and can travel long distances.
14. Communication processor, which converts the digital signals from a computer to analogue frequencies (signals), which can be transmitted over ordinary telephone lines.
15. A transmission mode in which transmission is done in both directions over a channel but only in one direction at a time.
18. A transmission mode which allows sending of message in one way only.
20. ASCII and EBCDIC
25. computer platforms dedicated to special functions such as database management, printing, communications, and program execution.
26. A topology in which each device has its own channel to a central point on the network.
