WebPage is the smallest data unit that the VM manages. Block is a sequence of bits and bytes. Block is made up of sectors. A page is made up of unit blocks or groups of blocks. A block is made up of either one sector or many sectors (2, 4, 6...), which means blocks have varied in sizes. Pages have a fixed size. WebOn a spinning disk, a sector is the minimum unit of transfer in both directions, both reading and writing. On flash memory, however, the minimum size of a read is typically much smaller than a minimum write. In essence, the sectors are numbered 0, 1, 2, etc. up to (N-1), where N is the number of sectors on the disk.
