What are hard-disk partitions, and why would you partition a disk?

This is a technical question that any IT support professional should be able to answer. When interviewing as an IT support specialist, the questions will range from very simple to very complex. Regardless of the complexity of the question, you should provide an answer that is brief and to the point. The interviewer will ask you follow-up questions if they need more information, want to explore the topic in more depth, or seek to test your knowledge of the topic. If you are asked a question and you don't know the answer, then admit this and describe how you would find the answer or resolve the issue.
