COMPUTERS AND CYBERNETICS

 

The computers or high-speed electronic machines of today have created entirely new technical possibilities in automatic control of industrial processes. First designed for solving mathematical problems, they soon paved the way for a new field of science cybernetics that studies general principles of control both in life and non-live systems. The importance of cybernetics is great in the sphere of engineering sciences. A newly developed field of knowledge is technical cybernetics. Its objectives are to control automatic industrial processes, to study problems of transmission of information and to develop new principles of automatic control.

One of the main problems of technical cybernetics is the development of control algorithms to be used in processing and control of information flows. The algorithms worked out for employment in control machines are called programs. These are based on subdivision of the computation process into simple arithmetical operations and on determination of the logical operations to be performed with a view to fulfil the program which gives the sequence of the machines and must be coded or expressed in the adopted code systems.

Two systems of computers are now created for control computer design.

One of these is the development of general-purpose control machines that may have much wider application but require more complicated logical circuitry and greater number of instructions and commands employed in the computer. This approach permits control of a great variety of industrial units with the aid of one and the same computer.

The second system utilizes modern microcomputer techniques to develop special-purpose machines designed to control a particular process. This leads to the creation of more easily operated and low-cost control computers. Tests of some control computers manufactured for specific industrial units have shown their efficiency and quite sufficient reliability.

In our country both systems of control are applied. Electronic digital computers perform both arithmetical and logical operations, making it possible to govern processes under rather complicated conditions.

COMPUTERS CONCERN YOU

When Ch. Babbage, a professor of mathematics at Cambridge University, invented the first calculating machine in 1812 he could hardly have imagined the situations we find ourselves in today. Almost everything in modern world is done with the help of computers the complicated descendants of his simple machine. Computers are being used more and more extensively in the world today, for the simple reason that they are far more efficient than human beings. They have much better memories and can store great amount of information and they can do calculations in a fraction of the time required by a human mathematician. No man alive can do 500,000 sums in one second, but a modern computer can.

In fact, computers can do many things we do, but faster and better. They can control machines at factories, work out tomorrows weather and even play chess, write poetry or compose music. Lets look now at some of the ways in which computers concern people in their daily lives and work.

Many people associate computers with the world of science and mathematics, but they are also a great help to scholars in other subjects: in history, literature and so on. It is now possible for a scholar to find a book or an article he needs very quickly, which nowadays when a million or more new books are published each year is quite an advantage. You tell the computer which subject you are interested in and it produces any microfiche you need in seconds.

There are also systems which are being developed to translate articles from foreign magazines by computer and to make up many lists of information which are needed in a modern library. So, computer can help us to deal with the knowledge explosion in many ways. One can imagine a time when libraries will be run by computers, without human being at all.

Or, lets take another example. When a man drives a car for long distances he has two problems: to keep the car at constant speed and watch that he does not run into the car in front of him. Engineers are now experimenting with a system which has a computer control of these two problems. The cars computer keeps the speed constant. At the same time the distance between the car and any other car in front of it is measured by a beam of light transmitted forwards. The beam meets the rear reflectors of the car in front and it is reflected back, which enables to measure the distance. This information is fed to the computer which adjusts () its speed control accordingly.

 

II. Read the text and define whether the following statements are true or false.

1. Charles Babbage invented the first calculating machine in the 18th century.

2. Computers play a very important role in modern life.

3. Computers are less efficient than human beings.

4. Computers can store great amount of information.

5. Its impossible to imagine a time when libraries will be run by computers, without human beings at all.

2. a) Computers are able to do many things.

b) Computers can control machines at factories, play chess, compose music.

c) Computers concern people in their life and work.

3. a) Computers are associated with the world of science.

HARNESSING THE SPEED OF LIGHT

 

When the American scientist Alan Huang revealed his plants to build an optical computer, most scientists considered this idea as hopeless. It was impractical, if not possible, they said, to create a general-purpose computer that could use pulses of light rather than electrical signals to process data. During one of the scientists lectures on the subject, a third of the audience walked out. At another one, some of the scientists laughed, calling the researcher a dreamer.

That was several years ago. Now the scientist demonstrated his experimental computing machine based on optics. It look him five years to develop it. The device a collection of lasers, lenses and prisms can serve as the basis for future optical computers 100 to 1,000 times as powerful as todays most advanced supercomputers. The potential applications are remarkable: robots that can see, computers that can design aircraft, processors that can convert spoken words into written text and vice versa. Such practical optical computers are still years away some would say light-years.

Yet many scientists are predicting that the device will have an impact similar to that of the integrated circuit which made small personal computers possible.

Photons, the basic unit of light beams, can in theory be much better than electrons for moving signals through a computer. First of all, photons can travel about the times as fast as electrons. And while electrons react with one another, beams of photons, which have no mass or charge, can cross through one another without interference. Thus, photons can move in free space. This could open the door to radically new and different computer designs, including so-called parallel processor that could work on more than one problem at a time instead of one after another, as todays new generation computers do.
