computer past present future
The passage discusses the history and future possibilities of computing technology. It outlines how computers have evolved from early machines like ENIAC to today's laptops and internet-connected devices. The passage also explores potential future technologies like quantum computers and DNA computers that could replace silicon-based processors. Quantum computers could perform millions of calculations simultaneously, offering vastly more power than today's supercomputers. DNA computers may also be much faster, smaller, and more sustainable than silicon chips. However, both quantum and DNA-based computing technologies remain early concepts that have yet to overcome challenges preventing real-world applications. The future of computing beyond silicon remains uncertain.
computer past present future
- 10. ENIAC
- 12. EDVAC
- 17. The computers we are using now can do the works very fast. The development of computers is very fast in the last 20 years The desktop computers has now changed to laptops and still smaller Today’s computers work on GUI
- 19. The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).
- 20. Today’s common-or-garden silicon based microprocessors will not provide the solution to tomorrows computing needs. Is there an alternative? Well, not yet, but there are some highly possible contenders for the next generation of computers:- QUANTUM COMPUTERS DNA COMPUTERS
- 21. QUANTUM COMPUTERS The computer we are using now, utilises a binary system 1’s and 0’s Quantum computers aren’t limited by this constraint Researchers at IBM have built quantum computers by using nuclear magnetic resonance (NMR) techniques to measure and manipulate the spin of individual atoms.
- 22. Cond…… Quantum computers have the potential to take computing to the next level, by providing computers that are millions of times more powerful and faster that today’s top supercomputer. quantum computers – which theoretically means they can work on a million calculations at the SAME TIME, whereas your silicon based microcomputer does one calculate and then moves on the next in a cyclic process Quantum computers could one day replace silicon chips, just like the transistor replaced the vacuum tube. But for now, the technology required to develop such a quantum computer is beyond our reach.
- 23. The genetic material of DNA (deoxyribonucleic acid) of every living cell has the potential to perform “calculations”. One day DNA might be integrated into a computer chip that could perform calculations many times faster than the most advanced computer known today.
- 24. Silicon microprocessors have been the heart of the computing world for more than 40 years
- 25. As long as there are cellular organisms, there will always be a supply of DNA. Unlike the toxic materials used to make traditional microprocessors, DNA biochips can be made cleanly . DNA computers are many times smaller than today's computers.
- 26. Current biomolecular computing technology is still far from overtaking the silicon chip This future computers discipline looking to find a way into real-world applications and a dream for scientists... Let us see what will happen in future….
