Callout Queue

I have to impliment a callout queue for a school project, and the assignment is very vague. The callout queue is supposed to simulate processes waiting for CPU time. I have to have a thread to act as the clock (sending interrupts and such), a thread to add objects to the queue, and one to remove them. I'm not sure I have a strong understanding of what a callout queue is, so I have some questions about it...

1) If a callout includes a "time to expire" and the queue is organized by this expiration time, then what, exactly, is expiring? The process? I'm not sure what this value is supposed to represent.
2) What is a "callback"?

Any links or general explinations are welcome. Thanks in advance.
