| Architects, Engineers, and Movie-Makers all turn to Computer-Aided Design, or CAD software when they want to draw plans, make 2 or 3-dimensional models of physical objects, or even apply photorealistic surfaces and lighting, to help them see their designs. The screen shot shown is of AutoCAD software from AutoDesk, one of the most popular CAD packages. |  |

| Engineers, Scientists, and Mathematicians use powerful mathematics tools to help them solve equations and work through problems more quickly. Tools like Mathcad, shown here, Matlab, Mathematica, Maple, and others let the user enter mathematics and solve them numerically or symbolically, and manipulate the numbers as graphs, vectors, etc. |  | |
| Even the people who write software use applications to help them do it more efficiently. Computer programmers are enabled by specialized programming software that helps them to organize large, sometimes obscurely-names sets of code files, find errors in the code, and package it up so it's easy to install. The program shown here is a development environment for Java programmers called JBuilder(TM), Borland. |
