High Quality Content by WIKIPEDIA articles! SciTech SNAP (System Neutral Access Protocol) is an operating system portable, dynamically loadable, native-size 32-bit/64-bit device driver architecture. SciTech SNAP defines the architecture for loading an operating system neutral binary device driver for any type of hardware device, be it a graphics controller, audio controller, SCSI controller or network controller. SciTech SNAP drivers are source code portable between different microprocessor platforms, and the binary drivers are operating system portable within a particular microprocessor family.
