Computer programs tell the computer what to do such as which information to identify and access, how to process it, and what equipment to use. Programs vary widely depending on the type of information to be accessed. Although simple programs can be written in a few hours, programs that use complex mathematical formulas or that draw data from many existing systems, require more than a year of work. Allot of programmers work together as a team under a senior programmer's supervision. Programmers write specific programs by breaking down each step into a logical series of instructions the computer can follow. They then code these instructions in a conventional programming language, such as C and FORTRAN. An artificial intelligence language, such as LISP or Prolog; or one of the more advanced function-oriented or object-oriented languages, such as UML, Java, C++, Visual Basic, or Ada. Programmers usually know more than one programming language and since many languages are alike, they can often learn new languages relatively easily. In practice, the language they know or the type of environment they generally work in such as mainframe programmer, object-oriented programmer, or Internet or World Wide Web programmer often refers to programmers. In many large organizations, programmers follow descriptions that have been prepared by software engineers or systems analysts. These descriptions list the input required the steps the computer must follow to process data, and the desired arrangement of the output. Many progra...
