Computer Program makes the computer life

Computer Program

“The Analytical Engine…can do whatever we know how to order it to perform.” by Ada Lovelace

Computer Program is a combinaion of instructions that performs a specific task when executed by a computer. Computer requires program to function and typically executes the program’s instructions in a central processing unit. A computer program is usually written by a computer programmer in a programming language. A part of a computer program that performs a well-defined task is known as an algorithm. A collection of computer programs, libraries and related data are referred to as software. Computer programs may be categorized along functional lines, such as application software or system software.
Ada Byron (1815-1852) was the daughter of the English poet Lord Byron. Under her mother’s guidance Ada was tutored from an early age in mathematics and science, she later married the Earl of Lovelace.
In 1835, Ada was introduced to Charles Babbage and learned of his ideas for his “analytical engine”. In 1842, Babbage was invited to give a seminar at the University of Turin in Italy. Interest in his work spread when an Italian engineer, Federico Luigi Menabrea, published an account of the lecture in a leading French scientist journal. Babbage asked Lovelace to translate Menabrea’s work; the notes and comments she made were considerably more extensions than the original paper and were published in their own right. In the last of her seven notes, Lovelace describes an algorithm that would enable the analytical engine to compute Bernoulli numbers. Given that this was designed specifically for use with a computing machine, it could be argued that she had created the first-ever computer program. But the machine was never built, do the algorithm was never put to the test.

Not all historians credit Lovelace so highly. Some claim that she merely documented Babbage’s work or at best that the algorithm was a collaboration. That said, Babbage believed that she had greater understanding than anyone of the potential for his work.
