My grandmother bought me a cell phone a while ago. My mom asked me what kind of cell phone my child is, but my grandmother bought it for me, saying, "Is there anyone who doesn't have a cell phone these days?" Actually, most of my friends have cell phones. I text with my friends, take pictures, and play games when I'm bored. In addition, I can use the Internet and watch TV on DMB on my phone. I don't think I can imagine a life without a cell phone anymore.
Information and Communication Technology Driving Social Change
In sports games such as soccer and baseball, wins and losses are also determined depending on who has more information from the opponent. Also, people who have weather information that it rains don't get rained on, but people who don't get rained on or buy umbrellas. As the importance of information increases, the development of information communication technology that can exchange information quickly and conveniently follows. Furthermore, the development of information and communication technology led to social change.
