A programmer is creating an application that needs to store a value indicating
if the user is logged in or not. Which of the following would be the BEST data
type to accomplish this?

,Mary is a data analyst for a large pharmaceutical company. The company
wants to know how their new organic line of over-the-counter cold relief
medications is being perceived by customers and what they can do to better
promote the product.
Mary has collected a significant amount of raw data and has analyzed it to find
connections and links between the data points. The insights are significant,
and now she needs to inform company management.
What is Mary's next step in the data analytics process?
Provide meaningful reporting with a system that includes search features,
charts, and graphs.
An employee submitted a support ticket stating that her computer will not turn
on.
Which of the following troubleshooting steps should you take first?
Make sure the power cord is plugged into the wall.
Make sure the surge protector is turned on.
When troubleshooting the power supply, always check the following before
opening up the computer:
Make sure the power cord is plugged into the wall.
Verify any surge protectors are plugged in and in the on position.
Make sure the power supply's switch is in the on position.
Only after you identify the power supply is the problem should you replace it.
The keyboard and mouse being unplugged will not prevent the computer from
powering on. Testing the power supply using a multimeter should be done
only after the obvious has been ruled out.
