24 Questions

1. ___________ communication lets you send and receive at the same time.

2. The bus topology connects each computer with its neighbors in a long _____.

3. The multiplexer is a device that allows a single communications ________ to carry data transmissions from many sources at the same time.

4. The ____ topology connects each computer to every other computer.

5. Most computers use an asynchronous protocol. Before each byte sent - it transmits a start bit - and after each byte - it transmits a stop bit. Without these bytes - the receiving device would not know when to start listening and when to stop - causin

6. Half-duplex communication lets you transmit and receive - but not at _____________.

7. One way of checking if a transmitted byte was sent accurately is by using a ______ bit - which has information on the number of 1 bits.

8. When transmitting data by ________ transmission - all the bits of a byte are sent at the same time.

9. A ___________ protocol transmits data at a fixed rate agreed by the sender and receiver.

10. Parallel is often used by _________ - and is faster than serial transmission - which sends bytes one at a time - sequentially.

11. An example of simplex communication is a ___________ - which can only receive signals - but will not transmit them.

12. The topology of a network is the ______ of the communication channels in a communications system.

13. _______ communication allows you to transmit or receive - but not both.

14. Many computers use full-duplex communication. For example - a ______ line - where both parties can talk at the same time.

15. The ____ topology connects all computers directly to one device - usually a switch.

16. These are known as serial transmissions. You can speed this up by using _________ transmission - which all of the bits in a byte are sent at the same time.

17. Examples of network topologies include the star - ring - ____ - and mesh topologies.

18. The ______________ processors that would typically be found in a larger organization include the front-end processor - concentrator - controller and multiplexer.

19. Transmissions which send one bit after another are known as ______ transmissions.

20. Bandwidth is the amount of data that can be sent over a ______________ channel line in one second.

21. Synchronous protocol does not need a ______ and stop bit to show the beginning and end of a byte - since it sends each byte at the rate agreed upon.

22. This is known as bandwidth. Channels with high bandwidth are known as broadband - while channels with low bandwidth are known as ___________.

23. An ____________ protocol transmits data with start and stop bits.

24. The ____ topology hooks each computer to its neighbor and the last computer to the first - making a loop.
