fifth-generation computer
The fifth generation computer refers to a new generation of computers with artificial intelligence, which has the functions of reasoning, association, judgment, decision-making, learning and so on. When will the development of computers enter the fifth generation? What is the fifth generation computer? There is no clear and uniform answer to such questions. In 1981, Japan announced that it would develop a fifth-generation computer that could \"hear, speak, read and think\" within 10 years, investing hundreds of billions of yen and organizing a large number of scientific and technological elites to fight. This grand plan once caught the world's attention and caused some Americans to panic for a while, and one even exclaimed that it was the \"Pearl Harbor on the technological battlefield.\" In retrospect, Japan's original research plan was only partially realized. To this day, no computer has been claimed as a fifth generation computer. But one thing is certain, in the future society, computer, network, communication technology will be trinity. Computers in the new century will free people from repetitive and boring information processing, thus changing our way of working, living and learning, and expanding greater space for survival and development for human beings and society. When the wheel of history turns into the 21st century, we will be confronted with a variety of future computers. The computer of the future will have a major breakthrough in the integrated processing power of pattern recognition, language processing, sentence pattern analysis and semantic analysis. It can recognize isolated words, continuous words, continuous language, and natural language (including spoken language) of specific or non-specific objects. In the future, humans will increasingly talk to machines. They will \"dictate\" a letter to a personal computer, \"discuss\" a program to protect clothing with a washing machine, or use language to \"subdue\" a disobedient tape recorder. The era of the keyboard and mouse is coming to an end. High-speed superconducting computer uses only a few thousand times less power than a semiconductor device computer, and it executes an instruction in a billionth of a second, dozens of times faster than a semiconductor device. The integrated circuit chips of superconducting computers made with current technology are only 3 to 5 square millimeters in size. Laser computer Laser computer is the use of laser as a carrier for information processing computer, also known as the brain, its computing speed will be at least 1000 times faster than ordinary electronic computers. It relies on laser beams entering an array of mirrors and lenses to process information. Similar to electronic computers, laser computers also rely on a series of logical operations to deal with and solve problems. The non-interference characteristics of the light beam under normal conditions allow the laser computer to open up many parallel information channels in a very small space, and the density is surprisingly large. A prism with a cross-section equal to the size of a five-cent coin can pass through many times more than all existing cables in the world.
Molecular computers Molecular computers are in the making. The United States Hewlett-Packard Company and the University of California, announced on July 16, 1999, has successfully developed the logic gate circuit in the molecular computer, its line width is only the sum of the diameter of a few atoms, the molecular computer's computing speed is 100 billion times that of the current computer, and will eventually replace the silicon chip computer. Quantum mechanics demonstrates that individual photons do not normally interact with each other, but when they are brought together with atoms in an optical harmonic cavity, they strongly affect each other. This property of photons can be used to develop information processing devices for quantum mechanical effects - optical quantum logic gates, and then manufacture quantum computers. Quantum computers use the multiple spins of atoms. Quantum computers can calculate on qubits and can calculate between 0 and 1. In theory, quantum computers are capable of outperforming any standard computer imaginable.
DNA Computer scientists have discovered that deoxyribonucleic acid (DNA) has a property that allows it to carry large amounts of an organism's genetic material. Inspired by this, mathematicians, biologists, chemists and computer experts are collaborating to create the liquid DNA computer of the future. The DNA computer works on the basis of instantaneous chemical reactions, interacts with enzymes, encodes the process, translates binary numbers into fragments of genetic code, each one a strand of the famous double helix, and then answers the question in a new DNA code. Compared with ordinary computers, the advantage of DNA computers is that they are small, but they can store more information than all the computers in the world today. The power and magic of the sixth generation of computer neurons is well known to all. In the future, people will build computer systems that can perform functions similar to the human brain, namely artificial neural networks. The most promising applications for neuronal computers are in defense: they can identify objects and targets, process complex radar signals, and decide which targets to destroy. The performance of neuronal computers such as associative information storage, natural adaptability to learning, parallel repetition in data processing will be extremely effective. Biological computer A biological computer is a computer built mainly with biological electronic components. It takes advantage of the switching properties of proteins and uses protein molecules as components to make biochips. Its performance is determined by the switching speed of the current opening and closing between components. A computer chip made of protein has a memory point only one molecule in size, so its storage capacity can reach a billion times that of an ordinary computer. An integrated circuit made of protein is only one hundred thousandth the size of an integrated circuit on a silicon chip. And it runs faster, only 10 to the power of 11 seconds, much faster than the speed of the human brain.
I think about the future of the computer, it should be like this. In the future, only the main computer has no monitor and other peripherals. The host, which is the same size as the mobile phone, can carry out three-dimensional projection, and the screen with strong three-dimensional sense is projected above the mobile phone, as if people are immersive, and supports virtual touch function. Not used to touch can also project a virtual keyboard, can rely on gestures to sense mouse operation, and now the holographic mobile phone is more advanced.
