As more things can be done on the Internet, more traditional jobs are being replaced by new ones part time translator, online medical consultation, outsourcing, and more. Another important invention is the mobile phone. This technology also first appeared in America and was spread to the rest of the world in just a few years. Small but powerful, the mobile phone permits people to communicate anywhere in anytime. As a result, peoples contact becomes easier. If a person wants to talk to his or her parents or friends, what he or she has to do is dial a number and talk. Now the 3G mobile phone technology, which first appeared in Japan, is developing rapidly.
