Timeline of technology-Communication
There were many changes since the 3000 BC, when humans were still using papyrus as a piece of paper and using drawings to illustrate what they meant. You see, now we are already using emails or social networking sites to communicate with friends or teachers. During the 2400 BCs when they still used the postal services they need to wait for a couple of days depending on the effectiveness of the service. Now, a message could be delivered in just seconds, using emails or the widely popular Whatsapp to deliver the message across to anybody in the whole wide world who is internet enabled (3G enabled or Wi-Fi enabled). All these changes have affected our lives and the society greatly. If one day you need to call an ambulance to your house because you granny had a heart attack, imagine we still have to wait for very long (30 minutes? 1 hour?) for it to arrive. Won’t your granny be dead by then?
