When men learned to use the horse, communication became much quicker. However, compared to the modern world communication was still quite slow

6、. Many parts of the world had no knowledge of events in other places. Later, the post was introduced and horse riders carried letters. This meant that communication was further improved. Horses drawn coaches could move people from town to town in quite a comfortable way. At the beginning of the last

These signals travel so fast that they could go nearly eight times round the world in one second. A special device

A few years ago there were not many radio stations in the world. Today there are many hundreds of radio sta

This means that listeners in one country can listen to programmes broadcast from another country. In this way information travels from country to country.
