- By stored-program computer, we mean a machine in which the program and the data are stored in memory.
- Most of the high-level language programming will use this kind of computer implicitly.
- However, the program that is stored is not high-level language text. It would be necessary to constantly parse this text, which would slow down execution immensely.
- Instead, one of two other forms of storage is used.
- An abstract syntax representation of the program could be stored.
- The identifiers in this representation are pre-translated, and the structure is traversed dynamically as needed during execution.
- This is the approach used by an interpreter for the language.
- A second approach is to use a compiler for the language.
- The compiler translates the program into the very low-level language native to the machine, appropriately called machine language.
- The native machine language acts as a least-common-denominator language for the computer.
- A machine that had to understand, at a native level, many different languages would be prohibitively complex and slow.
- Machine language is rarely programmed directly, since that would involve manipulating bits, with which it is easy to err.
- Instead, an equivalent symbolic form known as assembly language is employed
