This document discusses programming languages and their evolution. It defines a program, programming language, compiler, and interpreter. It provides examples of popular programming languages like BASIC, C, C++, COBOL, and FORTRAN. It distinguishes between low-level languages that computers can directly understand and high-level languages that are closer to human language and require compilers or interpreters. Popular historical high-level languages discussed include COBOL, FORTRAN, ALGOL, and BASIC. It defines a compiler as a program that translates source code into machine-readable executable code.

3. A program is a sequence of instruction written In
a language that the computer can understand
and there by process .The individual set of
such sequences of instruction or a collection of
such set can be turned as programs .

4. Programming Languages is a set of
grammatical rules for instructing a computer
to perform specific tasks. Example of
programming Language are BASIC, C,C++,
COBOL, FORTRAN and Pascal. Each
language has a unique set of keywords and a
special syntax for organizing program
instructions programming language can be
divided into two levels.

5. Programming Language
Low Level Language
High Level Language

6. Low Level Language
High Level Language
These language
are directly
linked with
computer can
understand these
languages and
therefore , are
called Low
Languages.
These Languages are
much closer to human
language code and
were developed to make
programming easier. The
dependency of these
languages is on
interpreter and complier
so that the computer can
understand and process
whatever is instructed in
High Level Language.

7. COBOL – Common Business Oriented Language – This
was , at one time ,the most common commercial language .
COBOL was complier for translation .
FORTRAN- Formula Translation – An engineering and
specific based language. It was developed in 1957 by
international Business Machines (IBM).
ALGOL- Algorithmic Language – It is used for both
scientific and engineering purposes.
BASIC- Beginners All –purpose Symbolic Instruction
Code – As the name suggests , it is an all- purpose high
level language . It was developed at Dartmouth College ,
USA , in the early 1960s .

8. A Complier is a program that translates a source
program written in a high Level Language [such
as a] into machine code for the appropriate
computer hardware. The Program can then be
executed on any computer without the need of
complier. A complex reads the complete
program checks for the error and reports it after
the error have been removed it converts the
Program into an executable program which can
be run on any machines without the need of
Complier.
