1-What exactly is electrostatic discharge (ESD)?
Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.

2-Perform the following research about the CompTIA’s Six Steps to troubleshooting, explain EACH step in DETAIL:
Step 1: Identify the Problem
In this first step you already know that there is a problem; now you have to identify exactly what it is. This means gathering information. You do this in a few ways:
Step 2: Establish a Theory of Probable
In step 2 you theorize as to what the most likely cause of the problem is. Start with the most probable or obvious cause. For example, if a computer won’t turn on, your theory of probable cause would be that the computer is not plugged in! This step differs from other troubleshooting processes in that you are not making a list of causes but instead are choosing one probable cause as a starting point. In this step you also need to define whether it is a hardware- or software-related issue. Step 3: Test the Theory to Determine
In step 3 take your theory from step 2 and test it. Back to the example, go ahead and plug in the computer. If the computer starts, you know that your theory has been confirmed. At that point move on to step 4. But what if the computer is plugged in? Or what if you plug in the computer and it still does- not start? An experienced troubleshooter can often figure out the problem on the first theory but not always. If the first theory fails during
