12. An interface standard can consist of four parts, or components they are the electrical component, the mechanical component, the functional component, and the procedural component.
13. The idea behind hot plugging is that the peripheral can simply be plugged in and turned on, and that the computer should dynamically recognize the device and establish the interface.
14. To achieve the even parity the parity bit is given by,
1 XOR 0 XOR 1 XOR 1 XOR 0 XOR 1 XOR 1 =1
Therefore the parity bit is 1.
15. With a Synchronous connection, the unit of transmission is a sequence of characters.
16. A primary that performs hub polling polls only the first terminal, which then passes the poll to the second terminal, and each successive terminal passes the poll along.
17. Frequency division multiplexing is used as the assignment of nonoverlapping frequency ranges to each "user" of a medium.
18. The device that is attached to the receiving end of the medium and splits off each signal to deliver it to the appropriate receiver is called the second multiplexor, or demultiplexer.
19. DSL(Digital subscriber line) is a technology that allows a high-speed data signal to traverse a standard copper-based telephone line.
20. The statistical time division multiplexing is a good choice for connecting a number of lower-speed devices that do not transmit data on a continuous basis to a remote computer system.
21. The run length encoding replaces any repetitions of the same bit or byte that occur in a sequence of data with a single occurrence of the bit/byte and a run count, or simply with a run count.
22. High humidity and wet weather can cause an increase in electrical cross talk over a telephone system.
23. When working with stop-and-wait error control, the amount of time a station waits before retransmitting a packet is called as timeout.
24. A Medium access protocol is the software that allows a workstation to place data onto a local area network.
