The operating systems (OS) of most current Personal Computers (PCs) are primarily concerned with the functions of setting up the interfaces for all the hardware components. There is little management of memory space for user programs resident therein. This is due to technology constraints and needs. The memory sizes of all the PCs are quite small at the beginning, so there is little need or extra space left to manage the memory in a more efficient way. Considering DOS as an example, frequently a user has to repeatedly load a utility (such as a compiler, an editor, script processor, word processing system, or spreadsheet, etc.) where he is using it repeatedly in an application section. Even if a PC increases its memory to half a million bytes or more, the only advantage to a user is to run bigger applications.
