what is communication? Communication is the ability to transfer knowledge and information from one part to another using different methods such as signals, speaking, sounds and many other methods. Throughout history, the methods of communication were developed as the needs of the societies changed. They needed faster and better communication devices to fulfill their growing needs. At the times of war, they needed safer communication devices so, that led to the birth of cryptography which was used since old times as a way to transfer classified information. In the early 1800's, the telephone was invented, which made communication even easier because it shortened the distances between everything. But the biggest evolution in the history of communication came with the invention of the internet by Tim Burners Lee in the early 1990's which turned the whole world into a small village. The evolution of the communication devices continues until today. So, because communication devices are very important nowadays, I wrote this article to show their development throughout history and to show the advantages and disadvantages of these devices in our daily life. I also wanted to answer the following questions:



Are modern communication devices really invading our world and are they eliminating other communication devices? And in what way?



 I hope you find all the joy and benefit you need in this article.
