Question

1. Which of the following best describes a transistor?

A) a small electrical circuit made from a semiconductor material such as silicon

B) a cable that transmits bits by means of light pulses along a glass or plastic fiber instead of electrical signals over a conductor

C) an older information system that remains in use because it still functions and is costly to replace

D) an electronic device that can accept, manipulate, store, and output data, and whose instructions can be programmed

2. An information system is used to centralize information related to voting behavior in Texas. One of the indicators measured by the system is the average waiting time to vote. The time people spend waiting in line to vote at each polling booth is aggregated for each region. This is then used to create a graph that depicts the average waiting times by location. According to this scenario, which of the following refers to information?

A) the waiting time of each voter

B) the graph with average waiting times

C) the waiting time of a specific polling booth

D) a single cell in the information system's database

Answer 1

Answer 1 : A) A small electrical circuit made from a semiconductor material such as silicon.

Explanation : Transistor refers to switching electric powers etc using the semiconductor here the electric circuit is explained made of semiconductor material.

Answer 2 : B) The graph with average waiting times.

Explanation : As the system is used to create a graph using various indications such as average waiting time, waiting time at each polling booth etc which is then used to create a graph.
