The file type in the I node indicates that the file

block Device (Blockdevice) is a random access device with a certain structure , the reading and writing of this device is block-based, he uses buffer to hold temporary data, when the condition is ripe, Write from the cache one time to the device or from the device to a single read-out into a buffer, such as a disk and file systemcharacter device (Characterdevice): This is a sequential data flow device in which read and write is performed by character, and these characters are continuously formed
Device Files are divided into two types: block device driver and character device drive. Character DeviceDrive is also known as a character device or raw devices for bare devices. Block device driver is usually a block device. Block DeviceThe driver transmits the transferred data with a fixed length.
