    In mathematics it denotes the factorial operation.
    Many computer languages use "!" at the beginning of an expression to denote logical negation: e.g. "!A" means "the logical negation of A", also called "not A".
    Some languages use "!" to denote a click consonant.

    != not equal to
    !< not less than

    Look up "Logical Operators" in what ever language you are looking at

    Neither. Or Both. It depends on the usage and purpose employed.

    Is it's appearing for you as a picture in a pop-up window of some program, with no explanation text? When you try to carry out a particular task?
    Surrounded by a yellow triangle?

    In that case it meant that the program is trying to bring something to the users attention.

    It could mean that the operation halted for an unexpected reason, or a warning that proceeding could have permanent unwanted affects, or just a windows update will be installed at shutdown time. We can't know without an idea of the programs that are causing it.
    You'll need to provide more information and background detail.

    Looks like an exclamation mark. Tell us more or you'll get bunch of useless (but still true) answers.

    ! in C means "not"

    Are you looking at an "i" upside-down?
