2.13), the programmer works with an abstraction of memory that is a linear array into which a compiler assigns variable locations. Variable X could be stored in location 1010 in this imaginary (or virtual) array. The virtual memory abstraction is implemented using the twin mechanisms of page ...
Programs, consisting of instructions (translated by an assembler or compiler, or contained within an interpreter), are normally stored on a medium such as a disk, and in order to execute, they must first be copied from the disk to the computer system's memory to make the instructions availab...
different processes. First, the editor creates a file that serves as input to the compiler; the compiler uses that input file to create a new executable file (in many steps — take a compiler course for details); finally, the new executable is then run. And thus a new program is born!

In Chap. 4 (Software), the user interface (interaction) with the computer hardware (Chap. 5) is implicitly specified as being via a compiler program which translates user-defined high-level language programs (e.g. C++ programs) into low-level assembly language programs. The latter are parsed...
