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