<div dir="ltr"><div>Hi All,</div><div><br></div><div>I was reading through the text, "The Design of the Unix Operating System" - Maurice Bach</div><div><br></div><div>While reading through the Buffer cache, I had the following query</div>
<div><br></div><div>Buffer data structure, has Buffer header + pointer to data area + pointers for Buffer Management.</div><div>Does this,"pointer to data area", corresponds to disk block or Logical Filesystem block ?</div>
<div><br></div><div>I am confused about this. </div><div><br></div><div>To add more, I am aware of the fact that disk block is of 512 bytes on the most of the hard disks and</div><div>logical disk block size ( depending on filesystem ) is of 4k in size.</div>
<div>what would be available in data area pointed in buffer ?</div><div><br></div><div>Thanks,</div><div>Satheesaran</div><div><br></div><br></div>
