I a reading Kerninghan and Ritchie's C programming language book and on page 37 it mentions byte sized bit patterns like :

'\013' for vertical tab .

'\007' for bell character .

My doubts :

  1. What is byte sized in it and and what's a bit pattern ?
  2. What relevance does this hold and where can I apply it ?
  3. Is it in any sense related to escape sequences ?

I can't seem to find any information what so ever about these byte sized bit patterns on the web . please help . thanks .
