I often come across the phrase 'block of data'. One such example is as follows.
'The basic file system exchanges fixed-sized pieces (blocks) of data with the device drivers, buffers those blocks in main memory, and maps blocks to their physical location.'
Is this the same as a page? If not, what are the differences?
A BLOCK is the basic unit of physical storage on a disk. A PAGE is the basis unit of memory allocation.
The PAGE size and the BLOCK size may or may not be the same size.
One might say that a memory PAGE is analogous to a disk BLOCK.
