Types of hardware device.
{"Image DocumentName": "Types of hardware device.", "Image ImageDescription": "Linux supports three types of hardware device: Character, A character device is accessed as a linear queue of bytes. The device driver places bytes on the queue, one by one, and user space reads the bytes in that order. E.g. keyboard. Block. A block device is accessed as an array of bytes in multiples of the block size. Block devices are accessed via the buffer cache and may be randomly accessed, that is to say, any block can be read or written no matter where it is on the device. E.g. Hard disks, floppy-drives, CD-ROMs. Network. Network devices are accessed via the BSD socket interface and the networking subsytems.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
