this is a new type of personal computer. You sit at home or in the office, press the keyboard, and it will tell you in a pleasant voice: "The radio is broadcasting an article, maybe you will be interested." While speaking, the laser printer has quietly printed out the article. This new personal computer is called the fifth generation personal computer.
It is the product of high-tech such as VLSI and artificial intelligence, and it is a computer that can recognize sounds and images and has the functions of learning and reasoning.
The fifth-generation personal computer is equipped with a computer accessory that can listen and speak like a human. When used with a computer, it can understand 2, words. Therefore, this computer can print out letters dictated by people; It can record what people tell it, and then it can inform you after it is done well. When the computer has mastered recognize voice's skills, it is possible to control electrical appliances remotely by telephone. For example, when you travel, when it is windy and rainy, you can call the computer to send out control orders and close the doors and windows; Let the rice cooker cook the rice so that you can eat when you get home.
This kind of computer also has an amazing capacity of micro-memory and a lot of software, so that the computer can be used for multiple purposes. It can guide the operator through the program while doing complex calculations or other work. For example, educational software can let the computer guide you to do your homework; Foreign language teaching software can teach students to pronounce correctly; Art lovers can also edit videos and make their own TV programs through computers.
the fifth-generation personal computer has an extraordinary memory function. Everything from encyclopedias to Ci Hai to postal codes, telephone numbers and birthdays of relatives and friends can be stored in the computer. When necessary, press the button and the computer will display it. It can automatically dial the phone and remind you of your birthday in time.
This computer can also write articles and draft documents for you. All you have to do is input your ideas into the computer through the keyboard, display them on the screen, and after being processed by the word processor, you can organize them into wonderful articles. After you are satisfied with the review, you can print it into documents or books by a matching laser printer.
Intelligent machine for enhancing intelligence
Although the existing computer has always been called "computer", it can only replace part of the functions of the brain, which is far from the human brain. People's thinking process, including information intake, combination, transmission and output, is carried out in the neural network. When a group of external information is input into the brain, almost all neurons will participate in the processing at the same time, which fully reflects the comprehensive ability and creative ability of the human brain. However, the current calculation can only be based on the output of the previous operation, and the next operation can be carried out. Therefore, scientists are creating all kinds of intelligent machines, such as learning machines that can read university courses by themselves, computers that can associate with them, and expert computers with extensive knowledge.
Experts from Yale University in the United States once made a smart phone, which could read English, French and Spanish newspapers and make concise summaries of articles. In 1978, the newspaper published the news of the death of anthropologist Margaret. After reading it, this smart phone made such a summary: "Anthropologist Margaret Meade died of cancer at the age of 76."
With this kind of intelligent machine, it is necessary to build a bridge between the brain and the computer, so that their information can communicate with each other. In other words, let the computer know what the brain is thinking and needs in time, and then it can actively provide all kinds of information to help the brain remember, reason and calculate, so that the potential intelligence of the brain can be developed.
Scientists are studying electroencephalogram (EEG) extractor and magnetoencephalogram (MEG) picker. Computers can grasp the brain information of brain activity through the changes of brain wave patterns and corresponding magnetic fields. American scientists have developed a brain magnetic measuring instrument and obtained the magnetic map of human brain activity. According to the magnetic signals of various parts of the brain, a specific program is compiled and transmitted to the computer so that the computer can understand these signals. Another scientist also invented a very subtle "neural phone", which can be directly transmitted to the brain through microelectrodes and computers to solve technical problems needed by the brain, so as to concentrate on creative thinking and solve the most valuable problems.
Maybe one day, if you want to solve any problem, just put on a magnetoencephalogram pickup and turn on the "nerve phone", all kinds of drawings of inventions and creations will emerge in your brain, and you will have an intelligent opportunity to remember, think, calculate, recall, compare and choose for your brain, so that human creativity can be brought into full play.
Is smarter than computers
Is a computer made of optical fibers and various optical components. Unlike ordinary computers, it does not rely on the flow of electrons in the circuit to process information, but relies on a small beam of low-power laser to enter the optical circuit composed of mirrors and lenses for "thinking", but it also has the functions of storage, operation and control.
The "power" of a computer is mainly determined by two factors: first, the running speed of computer components; The second is how closely they are arranged. From these two aspects, light is much superior to electricity. Photons are the fastest things in the universe, reaching 3, kilometers per second, and light beams can cross each other without any influence. Electrons can't. The speed of its movement in semiconductors is about 6-5 kilometers per second, and the highest speed is less than one tenth of the speed of light. In addition, in VLSI, there are more than 3 pins of some chip devices, and the arrangement density is limited. The non-interference characteristics of light beams enable scientists to open up many information channels in a very small space. For example, the optical converter of Bell Laboratories can be made so small that more than 2, channels can be installed in a device with a diameter of less than 2 mm..
Theoretically speaking, the operation speed of is can be increased to 1 trillion times, which is thousands of times faster than modern computers. Secondly, optical devices also have the advantage of large amount of information. A beam of light can transmit thousands of channels of information at the same time. However, there are still many problems to be solved in theory and technology. As the first step, scientists use the characteristics of low driving energy of optical computers to combine electronic converters with light to create a hybrid computer of light and electricity, and then change the "supporting role" of optical computers to make it the main force of the information technology revolution.
