These devices supplement the computer's memory, which, as we will see, can hold data and programs only temporarily. Physical structure that houses a computer's processor, memory, storage, communication ports and peripheral devices. Each of these components have a different purpose, which may be either accepting inputs, storing data or sending outputs. The semantic Web is an effort to enable lay people to find, share, and combine information available on the web more easily. The name was coined by Berners-Lee to describe “a web of data that can be processed directly and indirectly by machines.” It is a framework for data sharing among applications based on the Resource Description Framework . First Computer Program To Run On A Computer Personal computers are more for browsing the internet, reading news, or even using non-stressful applications. If you are planning on using more demanding software like Adobe Photoshop or playing PC games, looking into the latest CPU processo...

On the other hand, you may find some institutions discourage students from learning programming beforehand to avoid students learning ‘bad’ programming habits early on. Some institutions offer joint courses, in which computer science is studied alongside subjects such as mathematics, engineering and computing. The Pentium is the fifth generation of the ‘x86’ line of microprocessors from Intel, the basis for the IBM PC and its clones. The Pentium introduced several advances that made programs run faster such as the ability to execute several instructions at the same time and support for graphics and music. The first use of SIMD instructions was in vector supercomputers such as the CDC Star-100 and the Texas Instruments ASC in the early 1970s. Vector processing was especially popularized by Cray in the 1970s and 1980s by attached vector processors such as those produced by the FPS , and by supercomputers such as the Thinking Machines CM-1 and CM-2. Sun Microsystems introduced SIMD int...

In particular, spreadsheet software automatically recalculates the results when a number is changed. This capability lets business people try different combinations of numbers and obtain the results quickly. This ability to ask "What if . . . ?" helps business people make better, faster decisions. Officially known as the Track Write, the automatically expanding full-sized keyboard used by the ThinkPad 701 is designed by inventor John Karidis. The keyboard was comprised of three roughly triangular interlocking pieces, which formed a full-sized keyboard when the laptop was opened -- resulting in a keyboard significantly wider than the case. This keyboard design was dubbed “the Butterfly.” The need for such a design was lessened as laptop screens grew wider. Xerox PARC physicist Gary Starkweather realizes in 1967 that exposing a copy machine’s light-sensitive drum to a paper original isn’t the only way to create an image. So in 1971, Starkweather transferred to Xerox Palo Alt...
