`actions, such as clicking a mouse button or pressing a key, or system oc—
`currences, such as running out of memory. Most modern applications,
`particularly those that run in Macintosh and Windows environments, are
`said to be event-driven, because they are designed to respond to events.

`
`exclusive OR A Boolean operator that returns a value of TRUE only if both
`its operands have different values. Contrast with the inclusive OR opera—
`tor, which returns a value of TRUE if either of its operands is TRUE.
`Whereas an inclusive OR can be translated “this, that, or both,” an exclu—
`sive OR means “this or that, but not both.”
`An exclusive OR is often called an XOR or EOR.
`
`:> See also BOOLEAN OPERATOR.
`
`executable file A file in a format that the computer can directly execute.
`Unlike source files, executable files cannot be read by humans. To trans
`form a source file into an executable file, you need to pass it through a
`compiler or assembler.
