Operating System (OS)
The operating system allows the user to organize the computer's contents in a hierarchical structure of directories that include all of the following except:
a portion of memory is wasted because the core occupied by the assembler is unavailable to the object program.
it is necessary to retranslate the user's program deck every time it is run.
it is very difficult to handle multiple segments, especially if the source programs are in different languages, and to produce orderly modular programs.
