History of Computers

Human beings are quite slow in computations and tend to make mistakes, while the computers could make those computations very efficiently and accurately.  Need for efficiency and accuracy inspired humans to think about computers.

Mother of Computer Science:

Ada Lovelace was a British mathematician.Since early childhood her mother was actively pushing her towards mathematics. At the age of 17, Ada met an English mathematician Charles Babbage who was working on analytical engines. Ada got really fascinated by his ideas and later she contributed her own ideas and theories in the article  called “Analytical Engines” that was written by an Italian engineer(Luigi Federico Menabrea). Her ideas earned her a status of a mother of computer science.

Father of Computers:

Charles Babbage  was a British mathematician who successfully invented a “difference engine” in 1820s that could compile mathematical tables. Charles believed that there could be a faster and more efficient way to perform those operations, hence he decide to start working on creation of analytical engine( know as a first mechanical computer). Unfortunately due to lack of technology and insufficient funding, Charles weren’t able to finish his project. For his hard efforts, Charles was assigned a title of a father of computers.



Father of Computer Science:

Alan Turing was an English computer scientist who contributed to development of artificial intelligence and modern understanding of computer science. In addition,during the WW2, he worked for the British Government Code and Cypher School and invented the machine that could decrypt Enigma* messages. (Enigma machine was a cipher machine that was used for secret communication).His contributions, reduced the WW2 by 2 years and saved nearly 14 million lives(Copeland,2012).
For all his work and great efforts, Alan Turing was assigned a title of a father of computer science.


The first world’s computer:

The first world’s personal computer Kenbak-1, war released to the world in early 1971. The computer was designed by John Blankerbaker and was sold for 750$! Even thought, the computer was not really capable of running any applications programs, but it was really useful in helping programmers to learn the principles of programming. Unlike modern computers, Kenbak-1 was based on small TTL chips. Currently, there are 14 Kenback-1 machines in existence.
