why there is a need for minor number and major number for monitor/keyboard in pc?
why there is a need for minor number and major number for devices
(monitor/keyboard/mouse) which are one in number connected to pc .?
the minor number and major number concept is good for devices that
can be two or more in number connected to pc like floppy drive,hard
disk drive etc. but only singly connected device to pc can be easily
detected by system.then what is the need of major num and minor numb
in them?
