Also called bit density.The amount of data that can be packed onto a storage medium. Areal densities are generally measured in gigabits per square inch. The term is useful for comparing different types of media, such as magnetic disks and optical disks. Current magnetic and optical disks have areal densities of several gigabits per square inch.
In programming, a value that you pass to a routine. For example, if SQRT is a routine that returns the square root of a value, then SQRT(25) would return the value 5. The value 25 is the argument. Argument is often used synonymously with parameter, although parameter can also mean any value that can be […]
