I have learnt what is computer in the first lesson. The computer is composed of different hardware and software. Computers make our lives more convenient and easy to connect other people on internet.
Internet can shorten the distance between people. But how can we through the internet to contact other people or get the information ? In the earlier time, we had Web1.0. Web 1.0 can provide the data for people get use it. Later, we had Web 2.0. That is more enhancement tool.It's not only to view, but also can interact and connect with each other.
I think Web 2.0 is more better than Web 1.0, it is because Web 2.0 can start up the social circle. Web 2.0's characteristics are more obvious in social side, for example, forums, blog, wiki, instagram, you can input your data, and interact with strangers, share your ideas, finally, it may come up something.Otherwise, you can more easily to get the useful information from the internet.But internet may contain some potential danger and trigger a lot digital issues, such as cyberbullying or security problem, people can commit crimes through the Internet.
