See glossary(9):

block special file
      A special file associated with a mass storage device (such as a hard
      disk or tape cartridge drive) that transfers data in multiple-byte
      blocks, rather than by series of individual bytes (see character
      special file). Block special files can be mounted. A block special
      file provides access to the device where hardware characteristics of
      the device are not visible.

character special file
A special file associated with I/O devices that transfer data byte-by-byte. Other byte-mode I/O devices

include printers, nine-track magnetic tape drives, and disk drives when accessed in "raw" mode (see
raw disk). A character special file has no predefined structure.
