U2 L5 communication

      Communications links the whole world together.  In the past, people used to communicate by sending letters by using pigeons.  They used to travel using camels, donkeys, horses and on foot.  It was very difficult in the past and it took along time. But nowadays, it is very easy and takes less time.  People communicate using telephone, TV, satellites, email and internet.  Also, they travel using cars, buses, planes, trains and ships.
