History of computers final
- 2. Info storage and retrieval Entertainment Communication as well as accounting Running software and Calculating Computers have many uses today, however the general tasks that computers are programmed for are as follows:
- 3. The Abacus or Counting Frame • Calculating device used centuries before the written modern numeral system. • Is Still widely used by merchants, traders and clerks in Asia and Africa. Antikythera • An ancient analog computer, designed to predict astronomical positions and eclipses. • The instrument was designed and constructed by Greek scientists and has been dated between 150 to 100 BC.
- 4. First Generation Computers • Significantly slower processing speeds (.001khz) • Low amount of RAM (2 Kbytes) • Broke down often due to over heating Second Generation Computers Third Generation Computers • Much smaller than predecessor • Faster processing speeds • Cheaper to buy than first generation • More reliable, less frequent malfunctions • Increased processing speed far beyond any previous computer • Networking efficiency • Even smaller and used less energy
- 5. What Is VisiCalc ? VisiCalc is... Originally released for the Apple II The first spreadsheet program Considered the application that turned the microcomputer from a hobby for computer enthusiasts into a serious business tool.
- 6. Also known as personal computers, these computers whose size, capabilities and original sale price make them useful for individuals, and are intended to be operated directly by an end-user with no intervening computer operator. The World Wide Web is a system of interlinked hypertext documents that are accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks. PCs World Wide Web These two subjects intervened with one another by PCs gaining access to the WWW in 1994.
- 7. Multi Media Convergence Voice, Data and video devices arte able to share resources and internet with each other via one platform. The development of different technological systems to evolve toward performing similar tasks Multimedia refers to content that uses a combination of different content forms. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms.
- 8. The uses of the original computers are still the main purpose of computers but in this generation computers have developed many more diverse uses such as: Entertainment, Automatic construction of mechanics, Business tools etc. The next generation of computing seems very promising. With many new and improved forms of technology like nanotechnology and the further development of robotics and AI. I believe our world will soon evolve completely around the reliance and use of technology and it will become a huge factor in our lifestyle .
