1 , Artificial communication satellites are placed in an orbit around the Earth. They relay radio and television signals around the curved surface of the Earth and thus serve the purpose of intercontinental radio and television transmission. There are two types of satellites in the orbit: active and passive. As for active satellites, they are used to receive, amplify, and retransmit signals being sent for the purpose of communication. The function of passive satellites is only to reflect the transmitted signals from the surface of the Earth..:

1 Communication between INFORMATION SOURCES can be carried out through the combination of the sources into networks. Telephone and telegraph networks may serve as examples. Telex has been used for communication for a long time. Not long ago cable transmission has also become used for the same purpose. As for computer networking, it is also highly developed in every sphere of communication and is very popular locally and internationally.:
1 The RADIO-CONTROLLED SPACESHIP named Vostok was equipped with two-way radio transmitters operating on short and ultra-short waves. These transmitters enabled the cosmonaut to send signals to the Earth. What was the cosmonaut's pulse? Temperature? What were the altitudes of the spaceship? Electronic communications received the answers to these questions via radio, radar, and telemetry. German Titov was the second Soviet cosmonaut, who on August 6, 1961, rode the spaceship Vostok 2 seventeen times around the Earth in 25 hours and 11 minutes. German Titov communicated with the Earth by radiophone. He travelled at altitudes ranging from 178 to 244 km.:

1 As for underground lines, they usually include line conductors and insulators. Underground lines are laid under earth. They are mostly used in cities and in industrial areas. Lines used for energy transmission may be classed into the following three types: overhead, indoor and underground. Naturally, these types are different in construction and in the elements they are made of. As for overhead lines, they include line conductors, insulators and supports. Indoor lines include conductors, cords and buses. The conductors in indoor lines may include one wire or a combination of wires not insulated from one another. Underground lines mostly used in ________.:

1 The losses of a system including compressed gas-insulated transmission are rather low; they are considerably lower than those of cable transmission. Besides, unlike cables, compressed gas-insulated transmission system can be designed for ultra-high frequencies. The next advantage is that there is no external electric field in the system. As for the shunt capacitance, it is considerably less for a gas-insulated line than for a cable. A gas-insulated line can thus transmit power over larger distances than cable lines. The losses of a system are considerably lower than those of ________.:
cable transmission
transmit power
shunt capacitance
