A programming language is defined as a vocabulary and set of grammatical rules for instructing computers. The document outlines the historical timeline of programming languages, beginning with Ada Lovelace's contribution in the 1840s and highlighting key developments through the 20th century, including the invention of Fortran in 1954. It also lists significant programming languages introduced from 1967 to 1978, such as BCPL, LOGO, and C.

HISTORY OF PROGRAMMING LANGUAGE
In 1920’s the first recognizably modern electrically powered computers were
created. Hence the limited speed and memory in these computers forced
computers to write hand tuned ASSEMBLY LANGUAGE programs.
Then between 1963 – 1975 an high level programming language was
developed by KONRAD ZUSE for his Z1 computer. But this high level
programming was not implemented at thattime.
The first functioning programming language designed to communicate
instructions to a computer was early written in 1950 by JOHN MAUCHLY’S.

In the early 1950’s ALICK GLENNIE developed AUTO CODE, possibly the
first compiled programming language.
In 1954 FORTRAN was invented atIBM team by JOHN BACKUS, It was the
first highly used high level programming language.
