| Compilation | Programs (source language) are translated into machine code (machine language) so that they can be executed directly on the computer. Ex. C, COBOL, C++ Slow translation, fast execution |
| Compilation Process | |
| von Neumann Bottleneck | The speed of the connection between a computer's memory and its processor often determines the speed of the computer. Instructions often can be executed faster (CPU) than they can be moved back to the processor (RAM) for execution. |
| Pure Interpretation | Programs are interpreted by another program called an interpreter, with no translation. Advantage: easy implementation of programs, run-time errors can be easily and immediately displayed Disadvantage: slower execution and requires more space Ex. APL, SNOBOL, JavaScript, PHP |
| Pure Interpretation Process | |
| Hybrid Implementation Systems | Programs that are partially compiled and partially interpreted. A high-level language program is translated (compiled) to an intermediate language that is then interpreted. Advantage: Faster than pure interpretation Ex. Perl, Java |
| Preprocessors | A program that processes a program to expand embedded preprocessor macros just before the program is compiled. Ex. C Preprocessor: #include, #define |
| Programming Environments | A programming environment is the collection of tools used in the development of software. This collection may consist of only a file system, a text editor, a linker, and a compiler or it can include a large collection of integrated tools, each accessed through a uniform user interface. Ex. UNIX, Microsoft Visual Studio .NET |
