A. Block device is a device that can only be accessed in blocks, the size of the block is generally 512 bytes of integer multiples, common block devices include hardware, SD card, CD, Flash and so on. The driver is an integer multiple of the block from which the device reads and writes data. The minimum unit for block devices is block, on top of different systems, the block size is not the same, Linux is generally defined as 512 bytes. Each time we access a block device is the minimum Access uni
