Answer:
ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.
Following are two precautionary measures which should be observed when using any kind of ICT:
- Use of Antivirus: It can used to protect anything placed inside the technology especially from hacking and viruses which can create many issues.
- Backup Data: Creating a backup of the data stored in the device is important as it can be recalled when the device malfunctions. Backup of the data can be created through using USBs, CDs etc or through cloud storage
What are the options for this answer?
I think it is the model ET-2. Not quite sure.
Explanation:
The X's have been correctly placed in the chart
A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.
People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.
A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.
Answer: E. Never
geometric average return can NEVER exceed the arithmetic average return for a given set of returns
Explanation:
The arithmetic average return is always higher than the other average return measure called the geometric average return. The arithmetic return ignores the compounding effect and order of returns and it is misleading when the investment returns are volatile.
Arithmetic returns are the everyday calculation of the average. You take the series of returns (in this case, annual figures), add them up, and then divide the total by the number of returns in the series. Geometric returns (also called compound returns) involve slightly more complicated maths.
