Misc character devices
Character Devices, Major and Minor numbers Based on granularity of access, there are two classes of devices: Character devices are accessed as a stream of bytes. Eg: Keyboards Block devices are accessed in blocks. For instance, hard disks transfer data in blocks of multiple bytes at a time. The kernel uses major and minor numbers to identify the attached hardware devices. Major number usually tells us the type of device. Minor numbers are used to differentiate two or more devices with the same major number.
