A Brief History of Computers

The word ‘ computer ’ originally implied a person, who, under instructions from a mathematician, performed mechanical calculations. Mechanical calculating devices such as the abacus were often put to use to aid this process.

At the end of the Middle Ages, mathematics and engineering in Europe received a considerable boost, thus leading to the invention of numerous mechanical calculating devices. The  technology  for clockwork was developed by the early 17th century. The period between the early 19th century  and  early 20th century saw the development of a number of  technologies  which would be vital for the development of the digital  computer  later on. Some examples are the punched card and the valve. Charles Babbage was the first person to design a fully programmable  computer  as early as 1837. However, he was unable to actually construct his  computer  due to a variety of reasons.

Analog  computers  were increasingly used in the first half of the 20th century for a number of scientific computing needs. However, they became obsolete after the development of the digital  computer .

The first digital  computer  was the Atanasoff Berry  Computer  . It used a binary system of arithmetic, parallel processing, a separation of memory and computing functions and regenerative memory. Binary math  and  electronic circuits – both of which are used in today’s  computers  – were first used in the Atanasoff Berry  Computer .

In the 1930’s  and  1940’s, newer  and  more efficient  computers  were continuously developed. Gradually, they came to possess the key features which are present in modern day  computers  – digital electronics  and  flexibility of programming.

Among the more important machines to be developed during this time, the American ENIAC was prominent. It was a general purpose machine, but had an inflexible architecture. Later a far superior technique known as the stored program architecture was developed. It is the foundation from which all modern  computers  are derived.

Throughout the 1950’s,  computer  design [http://www.online-computers.info] was primarily valve driven. This was later replaced by transistor-driven design in the 1960’s. Transistor-based  computers  were smaller, faster  and  cheaper, and hence commercially viable. Integrated circuit  technology , adopted in the 1970’s enabled  computer  production costs to hit a new low, so that even individuals could afford them. That was the birth of the personal  computer , as it is known today.
