Answer:
D. Identify the problem.
Explanation:
There are six steps or stages in computer system troubleshooting. They are,
1. Identify the problem: In the stage of troubleshooting, the user is interviewed to get a description of the problem. Reproducing the problem is essential to confirm the described problem of the system before moving to the next stage.
2. Establish a theory of probable cause: when the problem is identified, a list of the possible cause of the problem is made.
3. Test the theory to determine a cause: each items on the list of possible cause of the problem is tested to confirm its actual cause.
4. Resolve the problem.
5. Verify full system functionality
6. Document the findings, actions and outcomes.
Answer:
Option C. The path from start to finish that passes through all the tasks that are critical to completing the project in the shortest amount of time
is the correct answer.
Explanation:
- Critical path is the term used in Project management.
- It can be known by determining the longest stretch for dependent activities and the time required for them to complete.
- A method known as "critical path method" is used for Project modelling.
- All types of projects including aerospace, software projects, engineering or plant maintenance need Critical method analysis for the modeling of project and estimation.

Answer:
16 RAM chips
Explanation:
To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:
Number of RAM chips required = Main memory size / size of one RAM
2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³
Hence:
Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16
Therefore 16 RAM chips are necessary
