Mathematica and Your Computing Environment
Mathematica runs compatibly across all major computer systems, and lets you exchange data in many standard formats.
The standard Mathematica system consists of two parts:
The kernel--which actually does computations.
The front end--which handles user interaction and notebooks.
From within one notebook you can run several Mathematica kernels--on local or remote computers.
Mathematica notebooks allow importing and exporting of many formats.
Notebook files contain only plain text and are completely portable.
Choose Show Expression from the Format menu to see the expression form of cells in this notebook.
Mathematica uses the Unicode standard to ensure portability of international character sets.
