In 1860’s the long distance communications are achieved by SNAIL MAIL but its a tedious process if a person posted one letter it takes more time to reach the destination so the scientists plan to make the communication faster and better so they decided to move on via electrical signals,The electrical signals are pointed to an electronic device and that device was called as Telegraph. Telegraph was introduced in the year of 1862 .


The telegraph is a electronic machine which is used to deliver messages in a encrypted or a coded manner. so the person who is in the destination side should decry-pt the message,After the decryption process  the receiver should knows what is the content that present on message that was delivered


At first the TELEGRAPH LINES are connecting only two cities, actually its the first attempt of communicating two different places, then the first message which was sent in between the two cities is shown in the above picture, LOL… Its not a good message…. then the telegraph lines are extended and crossing many cities and finally all over the world.



In 1876 Alexander Graham Bell invented the telephone and in the above picture shows the first voice over message through wire from one place to other really its an marvellous invention then CHARLES A.HENRY an Electrician make the telephone for the commercial use lets make an technical view they maintain a separate wired connection for all their customers and telephone exchanges are open all cities

The scientists want to make a communication between one computer to other computer.Finally they made a simple link to sharing information from one computer to other and the INTERNET is BORN…sounds cool


In 1991 A incredible thing is happened An English computer scientist TIMBERNERS-LEE Brings together a system that allows to share all sorts of information all over the world.
