1. What is an operating system and what is its purpose?
Software that controls the execution of computer programs and may provide various services.
2. What operating system do most computers come preloaded with?
Windows?
3. Besides personal computers, what other devices have operating systems?
Xbox 360!
4. Do all computers have operating systems? Explain
Well, all computers must have an operating system - otherwise, "Simply put, your computer would be useless without an operating system!"
5. What are the three most common operating systems? Are there other operating systems? Explain.
Probably the most common operating systems, known by myself, are Windows, Macintosh and Linux. I'm sure there are several more types of operating systems though, such as the one that my xbox 360 runs on. Mr. Powell also has a few listen on his website.
6. What is one reason why operating systems are coded rather than physical circuits?
Perhaps this way, it is easy to advance operating system functions and efficiency, as opposed to always physically changing the system.
7. What are the two main functions of an operating system?
Managing the basic hardware operations, such as the control of input and output, storage space, etc. Another function would be the management and interaction with applications software, such as printing and saving data.
8. What are the four types of operating systems?
Real-time operating system / single-user, single task / single-user, multi-tasking / multi-user
9. What are the first actions the computer takes when you power it on?
10. What is the bootstrap loader? What is its function?
A small program at the end of the boot record that can be used to boot an OS from the disk or logical drive.
11. How does the OS manage the processor?
12. What does an operating system do when two processes are multi-tasking?
13. What is thrashing?
In computer science, thrash (verb) is the term used to describe a degenerate situation on a computer where increasing resources are used to do a decreasing amount of work.
14. What is virtual memory management?
15. What is a driver?
An electrical circuit or other electronic component used to control another circuit or other component.
16. How can input/output capabilities of a system be enhanced?
17. How do application program interfaces make it easier for programmers?
18. What is a UI and GUI?
19. Why is Linux being open source significant?
20. What are some other devices that run on Linux?
21. What are 3 things you found interesting about operating systems that you did not know before?
One, they run in my game consoles! Two, I'm not sure. Three, that users can edit the coding to Linux. I had no idea.
22. What is a question that you still have about operating systems?
