    Some of the more common ones :

    "...ahem, as I was saying..."
    "...y'know that reminds me of a time when..."
    and:
    "...excuse me, but can I say something?..."

    Seriously, though - don't you ever do any research

    Do that first and then ask specific questions!

    Generally speaking, an interrupt is a bios signal that interupts the CPU's activity in order to tell it something important. There are up to 256 interupts possible, and each can have 256 (?) unique "services". In practice much fewer interupts are interupted. Higher priority interupts can interupt lower priority interupts. Examples are like the ones used by functions like kbhit(), InvalidateRect(), Sleep(), etc. For instance, ever noticed that when you dial into the internet with a modem, the first few seconds your mouse get's "stuck"? That's because the modem's interupt blocked other CPU activity...

    Anyway you need to read more about this in more detail, obviously. Check the internet and your favorite bookstore...
