Computer Programming Language :-

A programming language is a vocabulary and set of grammatical rules for instructing a computer to perform specific tasks.

Types of computer programming language:-

1. Low level language - Low level language are used to write programs that relates to the specific architecture and hardware of a particular types of computer.

• Machinery language/code - Machinery
language is the only language a computer
is capable of understanding. Officially, the
first programming language fir a computer
was ‘Plankalkul’,developed by “Konrad
Zuse” for the Z3 between 1943 & 1945.

• Assembly language - An assembly
language, often abbreviated asm, is any
low level programming language in which
there is a very strong correspondence
between the program statement and the
architecture machine code instruction.

2. High level language - High level language is programming language that enable a programmer to write programs that are more or lesz independent of a particular type of computer. Such language are considered as high level language because they are closer to human language and further from machine language.

• Problem oriented language - Computer
language designed to handle a particular
class of problem.
Example - COBOL was designed for
business, FORTRAN for scientific and GPSS
for simulation.

• Procedure oriented language - It focuses
on process rather than data. It takes a
problem as a sequence of things to be
done such as reading, calculation and
printing.

Example of high level language :-

1. BASIC for “Beginner's All-purpose
Symbolic Instruction Code” (John G.
Kemeny & Thomas E. Kurtz)

2. COBOL stand for “Common Business
Oriented Language ” (Dr. Grace Murray
Hopper)

3. LOGO - LOGO is an education
programming language designed in ‘1967’
by “Wally Feurzeig Seymour Papert” &
“Lynthia Solomon ”

4. FORTRAN stand for “FORmula
translation” (John Backus) is a 3rd
generation programming language that
was designed for use by Engineer,
Mathematicians and other users and
creators of Scientific Algorithms.

5. “C” programming language (Dennis
Ritchie) between 1972 & 1973

6. C++ (Bjarne Stroustrup) ‘1979’

7. JAVA (James Gosling) ‘1995’

8. Visual Basic - VB1.0 was introduced in
‘1991’. It is originally developed by “Alan
Cooper” which was further developed by
“Cooper ” and his associates under
contract in ‘Microsoft’.
