Exam 6: Errors, Error Detection, and Error Control

In TCP/IP,if a receiver just received some data and wishes to send data back to the sender,then the receiver should include an ACK with the data it's about to send.This is called ____________________.

A(n)____________________ is essentially a filter that allows the signal to pass in one direction only.

Attenuation can be eliminated with the use of repeaters for analog systems.

White noise is dependent on the temperature of the medium.

With ____________________ parity,the 0 or 1 added to the string produces an odd number of binary 1s.

____________________ is an unwanted coupling between two different signal paths.

Sliding window protocols have been around since the 1970s.

The ____________________ of a code is the smallest number of bits by which character codes differ.

If jitter becomes too great,correcting it can require the transmitting devices to speed up their transmission rates.

____ is not necessarily a form of error,but can indirectly lead to an increase in errors affecting the transmitted signal.

When working with stop-and-wait error control,the amount of time a station waits before retransmitting a packet is called ____.

For a receiver to be able to fix an error-in a process called ____-redundant information must be present so that the receiver knows which bit or bits are in error and what their original values were.

Simple parity can detect only an even number of erroneous bits per character.

An unfortunate side effect of noise during a transmission is that the transmitting station has to slow down its transmission rate.

____________________ is the continuous loss of a signal's strength as it travels though a medium.

If a receiver has just received one packet of data with bytes numbered 600 to 700,it will respond immediately with ____.

If impulse noise interferes with a digital signal,often the original digital signal cannot be recognized and recovered.

____________________ is the reflective feedback of a transmitted signal as the signal moves through a medium.

Isolated single-bit errors occur ____ percent of the time.

The CRC error-detection method treats the packet of data to be transmitted as a large polynomial.
