Evolution of Computers and Technology

When people began to count the numbers, they thought of devices which can track the numbers. The need for a device to do calculations along with emergence in commercialism and other human activities started the evolution of computers. Having the right tool to do calculations has always been significant for mankind. The Abacus may be the very first such device and it took hundreds of years to develop the Abacus to New digital computer. The first computer was created as an ordinary calculating machine in 19th century.

With the transit of time, many computing devices that include Napier bones and slide rule were invented. It took many centuries for the advent in computing devices. In 1642, a French mathematician, Blaise Pascal invented the very first operational automatic calculating machine. The brass rectangular box also known as Pascaline, used eight movable dials to add sum totals and eight digits only.

In 1694, German mathematician Gotfried Wilhemvoz Leibniz, extended Pascals design to do multiplication, division and also to find square root. This machine is referred to as stepped reckoner. The only drawback with this device is that it missed mechanically skillful precision in its structure and was not reliable.

The actual origin computing device is created by an English mathematician Charles Babbage in 1822. He proposed an engine to do difference equations, known as a difference engine. It could possibly print results automatically. Nevertheless, Babbage never quite made a fully functional difference engine, and in 1833, he stopped working on it at once.

In 1889, Herman Hollerith, also employed the Jacquards Loom concept to computing. One early success was the evolution of the ENIAC (Electronic Numeric Integrator and Calculator). After wards, EDVAC (Electronic Discrete Variable Automatic Computer) was invented. It was first computer produced by John Von Neumann. In the year 1949, EDSAC (Electronic Delay Storage Automatic Calculator) was developed by Maurice. Eckert-Mauchly Company invented UNIVAC (Universal Automatic computer) in 1951. In 1960, fastest electronic computer to access the time scale of 1 micro second and a total capacity of 100,000,000 words was evolved. During 1970s, the vogue for inexpensive computers made possible by integrated microchips (IC) and Microprocessors. These days utilizing VLSI (Very Large Scale Integrated Circuits), which are programmed using READ ONLY MEMORY is made. It could handle 32 bits at once, and can process 4,000,000 instructions at a stretch.

Beyond this level in computer history, many advances and changes have taken place, coming from the Apple-Microsoft wares, to the evolving of microcomputers and a variety of laptop or computer breakthroughs that have become an admitted part of our day to day lives. Without the initial steps of computer history, none of this probably would seem to be possible.
