the “Personal Computer” (PC). This created a revolution of sorts and it continued the trend towards smaller size, working their way down from desktops to laptops, palmtops and net books. It also paved the way introduced global web of computer circuitry- the internet. Electronic mail or e-mail allows users to type in a computer address and send messages.
Fifth Generation (Present and Beyond) This generation is in its infancy. Most famous example of this generation computer is “HAL9000” from Arthur C Clarke’s novel, 2001: A Space Odyssey. HAL could reason well enough to hold conversations with its human operators, use visual inputs, and learn from its own experiences. Using recent engineering advanced computers may be able to accept spoken word instructions and imitate human reasoning. The ability to translate foreign language is also a major goal of fifth generation computers. Advances in software and computers have made facial detection, touch and swipe possible. Retina displays and ultra-fast processing capabilities make computers more simple and easy to use.
Types of computers A computer is a machine that can take instructions, and perform computations based on those instructions.. These instructions are known as programs. Computers can also store and retrieve large amounts of data. Computers range from the very small to the very large. Some are capable of doing millions of calculations in a single second, while others may take long periods of time to do even the most simple calculations. But theoretically, anything one computer is capable of doing,
