High level languages:

High level languages (converted to machine code by compiler or equivalent) are much easier to program, as well as to understand. Several high level languages are in use today.

Best known are the FORTRAN (Scientific), COBOL (business) and BASIC (interactive) languages. Most recently introduced general purpose languages include PASCAL, ADA and C. Most  recent programming languages are called the 'fourth generation' or 'very high level' languages, generally as part of integrated program systems, such as DBMS, which facilitate users to program their own applications very easily: It is not necessary for users of a program or package to have any knowledge of the language in which the package is written, or indeed to know.
