The history of computers and evolution Computers have been around a lot longer than many people might imagine. The word "computer" has changed meaning over decades‚ but the electronic computer that we think of in modern times developed throughout the second half of the 20th century. Its popularity as a household item surged in the 1980s following the arrival of operating systems by Apple and Microsoft that mixed graphics and text‚ replacing the text-only systems of the 1970s. By the 1990s‚ computers

9/2/10 BRIEF HISTORY OF COMPUTERS In 1623 German scientist Wilhelm Schikard invented an analog machine that used 11 complete and 6 incomplete sprocketed wheels that could add‚ multiply and divide. In 1642 French Philosopher‚ mathematician and physicist Blaise Pascal invented a machine that added and subtracted automatically carrying and borrowing digits from column to column. In the early 19th century French inventor Joseph Marie Jacquard devised a special type of computer called the silk

There is no noun with the ability to represent modern life other than computer. Whether the effect is negative or positive‚ computers control nearly every aspect of our everyday life. Computers have evolved from bearing the role of strictly computing to having the ability of completing unthinkable tasks. Supermarket scanners calculate our grocery bill while keeping store inventory; computerized telephone switching centers play traffic cop to millions of calls and keep lines of communication untangled;

A Brief History Of Computers The history of computers starts out about 2000 years ago‚ at the birth of the abacus‚ a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around‚ according to programming rules memorized by the user‚ all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe‚ used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added

THE HISTORY OF COMPUTER VIRUSES A Bit of Archeology There are lots and lots of opinions on the date of birth of the first computer virus. I know for sure just that there were no viruses on the Babbidge machine‚ but the Univac 1108 and IBM 360/370 already had them ("Pervading Animal" and "Christmas tree"). Therefore the first virus was born in the very beginning of 1970s or even in the end of 1960s‚ although nobody was calling it a virus then. And with that consider the topic of the extinct fossil

The early foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks‚ such as the abacus‚ have existed since antiquity. Wilhelm Schickard built the first mechanical calculator in 1623.[4] Charles Babbage designed a difference engine in Victorian times (between 1837 and 1901)[5] helped by Ada Lovelace.[6] Around 1900‚ the IBM corporation sold punch-card machines.[7] However‚ all of these machines were constrained

History of generations of Computers The computers that you see and use today hasn’t come off by any inventor at one go. Rather it took centuries of rigorous research work to reach the present stage. And scientists are still working hard to make it better and better. But that is a different story. First‚ let us see when the very idea of computing with a machine or device‚ as against the conventional manual calculation‚ was given a shape. Though experiments were going on even earlier
