What is udev, Guys

[Aysheeah]

Hi, may ask a little here? What is udev? What does it have to do with devfs?

Thanks for the answer

udev and devfs manage the device files in your /dev directory in a dynamic way. This means udev and devfs take care to create device files for you, which is as important as convenient. Actually neither devfs or udev are required, but without one of them the setup will be much more difficult.

Any one want to add it more?
