HISTORY OF COMPUTER.

Computers truly made their mark as incredible innovations in the most recent too many years of the twentieth century. Be that as it may, their history extends back over 2500 years to the math device: a straightforward number cruncher produced using globules and wires, which is still utilized as a part of a few sections of the world today. The difference between an ancient abacus and a modern computer seems vast, but the principle making repeated calculations more quickly than the human brain is exactly the same.

The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done, giving rise to punch-card based computers that took up entire rooms.

 

Today, we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is a timeline of how computers evolved from their humble beginnings to the machines of today that surf the Internet, play games and stream multimedia in addition to crunching numbers.

Computers can be classified into three generations. Each generation lasted for a certain period of time and each gave us either a new and improved computer or an improvement to the existing computer.

First generation: 1937 – 1946; In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Computers of this generation could only perform single task, and they had no operating system.

Second generation: 1947 – 1962; This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). Storage media such as tape and disk were in use also were printers for output.

Third generation: 1963 – present; The invention of integrated circuit brought us the third generation of computers. With this invention computers became smaller, more powerful more reliable and they are able to run many different programs at the same time. In1980 Microsoft Disk Operating System (MS-Dos) was born and in 1981 IBM introduced the personal computer for home and office use. Three years later Apple gave us the Macintosh computer with its icon driven interface and the 90s gave us Windows operating system.
