Exam 6: Errors, Error Detection, and Error Control

NAK represents a positive acknowledgment.

A(n) _________________________ is an industry-approved bit string that is used to create the cyclic checksum remainder.

____________________ parity tries to solve the main weakness of simple parity-that all even numbers of errors are not detected.

The simplest error-detection technique is ____________________ parity.

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

____________________ is an unwanted coupling between two different signal paths.

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.

____ cable is the medium least prone to generating errors.

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 ____________________.

Sliding window error control is based on the ____________________ protocol.

____ is probably the most common form of error control.

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

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

How does longitudinal parity work?

____ error control is a technique usually associated with the Stop-and-wait flow control protocol.
