6. Read the following text with the dictionary if it is necessary. Perform the tasks given below: communication (2)

Television was used experimentally as far as 1930. But its popular use began only some ten years later. And in about twenty years colour television became dominant over black-and-white.

Audio and video recordings are most popular means of communication today. Also popular are filming and photography.

High-technology revolution in electronics influenced the sphere of communication and greatly changed it. The new technology used for space exploration influenced modern communication both in offices and home. It became possible for business people to communicate with their colleagues in faraway places.

Computers and word processors serve this purpose and are being widely used in many offices all over the world.

The new technology has also influenced communication in everyday life. For example, it became possible for people to receive television programs through cables. Modern cable is a complex wire system that makes it possible to transmit a number of television signals at the same time.

People today also widely use videotape recorders to record television programs. One of the most interesting inventions of today is also the usage of satellites for video and audio communication. People can receive programs through using satellites.

From the history of computer development

The first vacuum tubes computers are referred to as first generation computers, and the approximate period of their use was from 1950 to 1959. UNIVAC I (UNIVersal Automatic Computer) is an example of these computers which could perform thousands of calculations per second. Those devices were not only bulky, they were also unreliable. The thousands of vacuum tubes emitted large amounts of heat and burned out frequently.

The tradition, a smaller and more reliable successor to the vacuum tube, was invented in 1948. So-called second generation computers, which used large numbers of transistors, were able to reduce computational time from milliseconds to microseconds, or millionths of seconds. Second-generation computers were smaller, faster and more reliable than first-generation computers.

Advances in electronics technology continued, and microelectronics made it possible to reduce the size of transistors and integrate large numbers of circuit elements into very small chips of silicon. The computers that were designed to use integrated circuit technology were called third generation computers, and the approximate time span of these machines was from 1960 to 1979. They could perform many data processing operations in nanoseconds, which are billions of seconds.

Fourth generation computers have now arrived, and the integrated circuit that are being developed have been greatly reduced in size. This is due to microminiaturization, which means that the circuits are placed now on a single chip. A chip is a square or rectangular piece of silicon, usually from 1/10 to 1/4 inch, upon which several layers of an integrated circuits are etched or imprinted, after which the circuit is encapsulated in plastic or metal.
