1. List three situations that might demand a real-time operating system and explain in detail the system characteristics that persuade you to do so.

2. Give at least two reasons why a regional bank might decide to buy six networked servers instead of one mainframe.

3. The boot sequence is the series of instructions that enable the operating system to get installed and running. In your own words, describe the role of firmware and the boot process for an operating system of your choice
