COMPUTER HISTORY
Generally the computer history is wrongly recorded in many websites and books.
These books are danger to his referrers. Because instead of knowledge they wasting their precious time. with tis knowledge they unable to achieve any things.
The history of the computer is starting with the innovation of ABacuse. The ABacuse was invented by chines scientist.
The first computers were people! That is, electronic computers (and the earlier mechanical computers) were given this name because they performed the work that had previously been assigned to people. "Computer" was originally a job title: it was used to describe those human beings (predominantly women) whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would quickly set in, leading to carelessness, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize (that is, find a mechanism that can perform) this task.
computer history can be tracked back from 2000 B.C. It began with an analog machine. a chines scientist invented mechanical device called ABacus, Which was used to add and subtract the numbers. It consists of beads that could slide over wires. These wires represent columns right most columns.Right most columns represent units and the next column represents tens and so on. by moving appropriate beads one could represent various numbers.The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator (multiplication and division are slower). The abacus is often wrongly attributed to China. In fact, the oldest surviving abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today, principally in the far east. A modern abacus consists of rings that slide over rods, but the older one pictured below dates from the time when pebbles were used for counting (the word "calculus" comes from the Latin word for pebble).
In 1933 The charles Babbage who is called father of the computer developed a analytical engine which could be programmed by coding instructions on punched cards. Later during 1940's john Von Neuman revolutionized the size designing the computers by implementing binary number system 'using 0 and 1' and storing instructions internally. Till 1950 computers were very hege in size and used only for scientific purpose.
The developments in computer that yielded personal computer.
