DKMS
DKMS stands for Dynamic Kernel Module Support. It is designed to create a framework where kernel dependent module source can reside so that it is very easy to rebuild modules as you upgrade kernels. This will allow Linux vendors to provide driver drops without having to wait for new kernel releases while also taking out the guesswork for customers attempting to recompile modules for new kernels.
Driver
A device driver, often called a driver for short, is a program that allows the operating system or some other program to interface correctly with a peripheral device such as a printer, a network PC card or the PERC H200 card.
DUD (Driver Update Diskette)
