1.3 в ХХстолітті (в 20столітті)

1.4Яке місце відіграє його географічне положення в історії?Як воно перетворилося від давніх часів до сучасності?Які перспективи розвитку має Королево?Ця історична задача спонукає вас провести дослідження та аналіз, щоб зрозуміти, чому Королево стало унікальним містом і важливим об'єктом в історії світового розвитку.

nastyakostych: а там де 1.4. перша загадка його то кого і ще можна відповіді до загадок?

Is there an End to the Computer Race?

Today the word electronics» is in general usage. Millions of people have electron watches. There are a lot of various radio and TV sets, video cassette recorders and CD players in our houses In factories and plants we are surrounded with electronically con- trolled machines and instruments, we are carried by airplanes, ships, trains and cars with built-in electronic devices, and satellites circle the globe. In other words, we are living in an electronic world.

And the center of this world is a tiny silicon platel of a few square millimetres, an integrated circuit², or a chip³, as it is more commonly known. The integrated circuit is undoubtedly one of the most sophisticated inventions of man, science and technology. It is in the heart of every electronic device and the more cassette re- corders, TV sets and computers we need, the more integrated cir- cuits are required.

When we speak about a further development of computers we mean not only quantity, but also high technology and high speed. As the operation of an integrated circuit depends on microscopic <<components», the purity of all materials and the cleanness at the plant they are produced at must be of the highest quality. A con- tinuous search is going on in laboratories throughout the world for more perfect, reliable and high speed electronic circuits.

In the past it took scientists and researchers a whole lifetime to make a few thousand calculations, whereas for a modern computer this task is a matter of a few seconds. At present computers capable of performing billions of operations a second are required. Super- computers are different from ordinary computers. The ordinary computer does the computations operation by operation, while thesupercomputer operates like a brain: all operations are being done simultaneously.

In the next few years engineers will complete the work on com- puters of above 2 billion operations a second. It will take a few more years to produce a 10-billion operations computer. The fifth-generation computers performing 100 billion operations a second will become available in the near future. Is there an end to this race?

According to some researchers, we are close to what can be re- garded as a true physical limit. But other specialists think that pho- tons will make the operation a thousand times faster. This means that in the future it will be possible to expect the appearance of photon computers and that computations will be done by means of light. Light has several advantages over electronics: light beams are faster, travel in parallel lines and can pass through one another without interference?. Already, the optical equivalent of a transis- tor has been produced, and intensive research on optical-electronic computers is being carried out in a number of countries around the world. In a few decades a new age of light may replace the still youthful electronic age. The race is going on.
