 ## Direct Memory Access (DMA)
 In order to let CPU execute process instructions while data is being transferred from disk to memory, direct memory access (DMA) is used.

 ## Fix-sized memory blocks
 In this scheme, memory is partitioned into blocks of the same size. Every block has the same number of bytes, which makes it easier for the system to keep track of which portions of memory are allocated or available.
