Which of the following statements most accurately describes the difference between down time and response time?

1. Response time is the period of time when an information system is not operational and available for use whereas down time is the amount of time between a user action and the response from the information system.
2. Response time is the moment information is gleaned from the computer whereas down time is the period when the system is off.
3. Response time is the amount of time between a user action and the response from the information system whereas downtime refers to the period of time when an information system is not operational and available for use.
4. Response time occurs when the software is downloaded whereas down time refers to the period of time it takes for the software to activate.

Answer to Question 1

3
Rationale: Response time is the amount of time between a user action and the response from the information system. For example, after the user selects a laboratory test from a menu, the system requires a certain amount of processing time before that result can be viewed. Downtime refers to the period of time when an information system is not operational and available for use.

Answer to Question 2

3
Rationale: ATM service is a high-speed data transmission link that can carry large amounts of data quickly. Speeds range from 0.45 megabits per second (Mbps) to 2.48 gigabits per second (Gbps). ATM works well when large sets of data, such as MRIs, need to be exchanged and discussed. T1 lines are high-speed telephone lines that may be used to transmit high-quality, full-motion video. T1 is not appropriate for quickly carrying such large amounts of MRI scan data.
