• DAdvanced Configuration and Power Interface (ACPI)

• A
  71% (27)
• B
  16% (6)

Explanation

Energy Star rating is an international standard for energy efficient consumer products. The Energy Star rating is an international standard for energy efficient consumer products. Devices carrying the Energy Star logo are products, such as computer devices, peripherals, kitchen appliances, etc. These products generally use 20% to 30% lesser energy than required by the federal standards. The Energy Star program was created by the 'United States Environmental Protection Agency' (US EPA) as an attempt to reduce energy consumption and greenhouse gas emission by power plants. The program has helped in spreading the use of LED traffic lights, efficient fluorescent lighting, and power management systems for office equipments. Answer option C is incorrect. Trusted Computer System Evaluation Criteria (TCSEC), frequently referred to as the Orange Book, is the centerpiece of the DoD Rainbow Series publications. It is a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system. TCSEC was used to evaluate, classify and select computer systems being considered for the processing, storage and retrieval of sensitive or classified information. It was replaced with the development of the Common Criteria international standard originally published in 2005. Answer option B is incorrect. The standby mode is a power saving feature for computers. In this mode, a computer does not shut down completely. The computer goes to low power state and, as a result, it consumes less power. When the computer resumes from the standby mode, full power is restored to its devices. During the standby mode, if the power supply is disconnected or interrupted, data might be lost. The standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do not need to enable this mode manually. This mode is not available in non-ACPI and non-APM based computers. Answer option D is incorrect. The Advanced Configuration and Power Interface (ACPI) is a powermanagement specification developed by Intel, Microsoft, and Toshiba. It enables an operating system to control the amount of power supplied to each device attached to a computer by turning off peripheral devices when they are not in use. It defines power management on a wide range of mobile, desktop, and server computers and peripherals. It also enables manuurers to produce computers that automatically power up as soon as a user touches the keyboard. http.//en.wikipedia.org/wiki/Energy_Star
