Answer:
The answer is Stimulus generalization
Explanation:
Stimulus generalization is an example of classical condition. Classical conditioning takes a stimulus that does not cause a particular response (neutral stimulus) and then pairs it repeatedly with an unconditioned stimulus that will cause an unconditioned response. In the case of Stimulus generalization, I will give an example of a subject presenting food to a dog once they ring a bell. Lets say that you have taught a dog to salivate every time it hears a bell ring. If you took another bell that has a similar sound and rang it, the dog would still salivate and come pick its food. This is a perfect example of Stimulus generalization. The dog has responded to a new stimulus as if it was the initial conditioned stimulus.

Answer:
A. an instance of the same data is stored in two or more places in the database.
Explanation:
Giving that Update Anomalies usually occur when the designated user person in keeping records or record master stored a particular data in more than one in a database. This is what is called duplication of data and is termed an irregularity on the part of the record keeper.
Hence, the correct answer to the question is " A. an instance of the same data is stored in two or more places in the database."
Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.
