Dictionary of Computers - parameter
parameter
Variable factor or characteristic. For example, length is one parameter of a rectangle; its height is another. In computing, it is frequently useful to describe a program or object with a set of variable parameters rather than fixed values.
For example, if a programmer writes a routine for drawing a rectangle using general parameters for the length, height, line thickness, and so on, any rectangle can be drawn by this routine by giving different values to the parameters.
Similarly, in a word-processing application that stores parameters for font, page layout, type of justification, and so on, these can be changed by the user.
