In the 1950s and 1960s, computers were used for making complicated calculations for designing power grids in a reliable way and optimizing the use of the different power plants. In a second phase starting in the late 1960s, computer systems were developed for real time monitoring supporting ...
The first generation of computers used vacuum tubes, which were bulky, unreliable, and consumed a lot of power. These computers, like ENIAC, were massive in size and limited in processing capabilities. The second generation of computers, developed in the 1950s and 1960s, replaced vacuum tubes ...
Computers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computer’s progress in the ability to learn from experience.Because the game requires logical reasoning, chess would seem to be perfectly suited to the ...
The first computer system (系统) was introduced for use in business in the middle of 1950s. Since then, the number of computer systems used in business, governments, and institutions (公共机构)has grown rapidly. In 1975, about 250, 000 systems were in use in the United States. This ...

These computers didn’t use the same kind of components as we do today (not to mentionsoftware). The computers in the 1940s and 1950s were mostly based onvacuum tubes. Transistors showed up late in the game, and integrated circuits were just a distant dream and didn’t start showing up...
Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to...
