![dfsaccx.jpg](https://cdn.steemitimages.com/DQmXPq3SLssbwuFqDSJo47zmtvfMq8ppkkAM552FKjEeL9Z/dfsaccx.jpg) **I made it using illustrator** There was a time when people communicate with others by horse or by sending men or by pigeon. On that time, it was impossible to know about a man who lived in other country. People barely know the people who lived in the next village. There was no concept of globalization or any international business. People only do business among their own territory. There was such a time when there was no money, people exchange products. ![bird-ge2095942c_1920.png](https://cdn.steemitimages.com/DQmc4VrGrE6zxb1hsWPsTqa6B9Qe5qyfSEPZwBb3HnhADTU/bird-ge2095942c_1920.png) **I took this picture from the net. Here is the [Source](https://pixabay.com/de/illustrations/vogel-buchstabe-botschaft-hinweis-5679935//)** Then, there comes an era where people start knowing peoples not only lived on their country but also the people who lived in other country. Ships are introduced in their live. People start communicating using ships. They start crossing sea by it. It introduced the idea of globalization. People start seeing various products from various country. International business started. It increases the communication speed. In previous days, where we can go by walk in 1 month, by using ship the time decrease at 7 days or like that. ![train-gc0e609385_1920.jpg](https://cdn.steemitimages.com/DQmRbj4VuR3544uK8MjqcVYdtzzpkvfj166aGvrzYiJs9ng/train-gc0e609385_1920.jpg) **I took this picture from the net. Here is the [Source](https://pixabay.com/de/photos/zug-eisenbahn-transport-60539/)** On land communication system put a great impact. Bus, train, bike, car etc. were introduced at land. It makes the communication system efficient. Where it was needed days after days for going but by using bus or train, we can go there at a very small-time. ![container-ship-g7f130e6ad_1920.jpg](https://cdn.steemitimages.com/DQmRBYczZfihp37c8C1z3ExT4mKgGhU6uHiBKWQXwp5ppPn/container-ship-g7f130e6ad_1920.jpg) **T took this picture from the net.Here, is the [source](https://pixabay.com/de/photos/containerschiff-container-transport-6631117/)** Then comes airplane, rocket, submarine etc. By using airplane, we can go at any side to the other side of the world within day. Rockets are used in satellite technology, by using it we are now travelling in space. Communication on earth is becoming very easy nowadays. We are now going to another planet or space. Submarine is a communication technology used under the water. It was mainly not used for communication, but it is used for war. Therefore, it is a communication technology. ## Conclusion At last, we can say that the earth saw a lot of things. It saw pigeon for communication, horse and now it is seeing bus, train, airplane etc. Really, communication system develops a lot. And there is a saying that, a country is as developed as its communication system is developed ## Source - https://en.wikipedia.org/wiki/Communications_system Transportation Systems - https://link.springer.com/book/10.1007/978-981-32-9323-6
