A computer is a machine that manipulates data according to a list of instructions. The first devices that resemble modern computers date to the mid-20th century (around 1940 - 1945), although the computer concept and various machines similar to computers existed earlier.

Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. http://linksdb.net/%cat_tags%/ en-us Hand-picked, best of best technology and gadget news that appeals to the cool factor as well as the practicality of advancements or must-have computer hardware, software, and electronics. http://www.gadgetadvisor.com 11.00
