“I was in Los Angeles America and you was in Ankara Turkey yesterday. Now, I am in Ankara Turkey, and you are in Los Angeles America. We’re separated over 3060.32 km. “
Time and distance sometimes are said to be limitation of human activity. If we are not in same place, it will be difficult on us for working together or collaborating. Distance separation like we could be in same time, but we are in different location. If we have different time zone, we also have difficulty on it. From the first sentence, I am in Los Angeles and at the same time you are in Ankara. Both of us separated 3060.32 km, that is very long distance. Time separation, it could be time zone distance, the differences of holiday, or others. But what are the hardest separation today?
If we lived in years of1600 or 1000, I believed that both of them had great impact on human being. At that time, the world still unexplored. The theory of the earth was still developing or in other words people was exploring the earth. It was impossible for human being to work and collaborate together. The information shared slowly and limited. For simple example : supposed to be me and my friend at that year. Suddenly my friend moved to other city. So, at the end, we were separated by distance. In this condition, it was difficult to communicate and the most possible communication was letter. Communication only using letter would take long time. It the effect, the respond also would take long time too. The information could be invalid when the letter came since the longest journey that took.
To overcome this problem, people started to developing the device that can help sending the message in instant time. In 1900, telegraph was found. In that era, people could send the message in short time but the information in that message was limited. Technology is continued its development. So telephone was born, then continued to mobile phone, and the last, internet was born.
Using the internet, people could do everything. Today, almost people rely on their activity on internet. By internet, the communication ways also were born such as email, instant messenger, voice call, or even video call. If we classify the kind of communication ways in Internet, we could call the first one is synchronous communication such as email and asynchronous communication such as voice call. Because of internet, the communication price is very cheap.
