Programming Languages

As noted earlier, computers work only with binary information. This machine language is really nothing more than a series of Os and Is strung together. Machine language, however, is a difficult way for most people to communicate with a computer. To simplify things, a number of high-level programming languages were created. These are much simpler to use and understand because of their similarity to the everyday language of human communications. These programming languages are translated into a code the computer understands, using the firmware installed in it by the manufacturer.

Among the most widely used languages are:

FORTRAN: (Formula Translator). It is used primarily in medical, scientific, and technical applications.

COBOL: (Common Business Oriented Language). It is one of the most popular business and accounting languages.

BASIC: (Beginners All Purpose Symbolic Instruction Code). This is as close to English as current programming languages come. BASIC is supplied with many personal computers, by the manufacturers.

PASCAL: (Named for the Seventeenth-Century French Mathematician Blaise Pascal). This is a popular programming language with many microcomputer users, who consider it easy to learn.

No matter which language a program is written in, the languages generally share four fundamental activities. They:

1. Provide a method for getting something into the computer, and getting it out again

2. Make comparisons

3. Decide what activities need to be performed

4. Repeat tasks until a particular job is completed

With the wide variety of software packages on the market that meet the needs of most users, it is probably not as important to learn a programming language as it once was for the average user.
