title: File Access method in Linux
body: <p>Read in text books that there are mainly two file access methods; sequential and direct. Which one we are using in Linux?</p>
  
  <p>In read command we are giving the how much bytes to read and to which buffer. So we are having sequential access in Linux?</p>
  
  <p>But physically we have files stored is blocks? I couldnt relate to it. </p>
  
  <p>Whether direct access possible in Linux? </p>
  
  <p>I read about these access models in Operating System Concepts by Galvin</p>
