Originally made of cotton or flax, most modern webbing is made of synthetic fibers such as nylon, polypropylene or polyester. Webbing is also made from exceptionally high-strength material, such as Dyneema, and Kevlar. Webbing is both light and strong, with breaking strengths readily available in excess of 10,000 lb (44.4 kN)
In computer programming, a parameter is a special kind of variable, used in a subroutine to refer to one of the pieces of data provided as input to the subroutine. These pieces of data are called arguments. An ordered list of parameters is usually included in the definition of a subroutine, so that, each time the subroutine is called, its arguments for that call can be assigned to the corresponding parameters.
