Which of the following is intended to be used in all applications runs on mainframe computers ?
The correct option is D PL/1
PL/1 is intended to be used in all applications runs on
mainframe computers.
PL/I is a third-generation ( 3GL ) programming language
developed in the early 1960s as an alternative to assembler language (for
low-level computer processing functions), COBOL (for large-scale business
applications), and FORTRAN (for scientific and algorithmic applications). PL/I
stands for "Programming Language 1".
Mainframe computers (colloquially referred to as
"big iron") are computers used primarily by large organizations for
critical applications; bulk data processing, such as census, industry and
consumer statistics, enterprise resource planning; and transaction processing.
A computer language is the way that a human communicates with
a computer. It is needed because a computer works only with its machine
language (bits and bytes). This is slow and cumbersome for humans to use.
Therefore, we write programs in a computer language, which then gets converted
into machine language for the computer to process.
There are many computer languages, and they have been
evolving from machine language into a more natural way of writing. Some
languages have been adapted to the kind of application that they intended to
solve and to the kind of approach used in the design. The word generation has
been used to indicate this evolution.
