LF-4 First, people can get and send information easily on the Internet. They can access information at almost any time. People can use the Internet to communicate in many ways. It's easy to send pictures, videos, and messages, so people are sending and viewing a lot of them. However, this may also be a problem. People are spending too much time on their smartphones and computers. 3» A second difference is content.

However, nowadays, almost anyone can create and upload content to the Internet. That means we can get much more information, but we have to be careful. We don't always know who made the content, and some of the LF-3 information may be incomplete or incorrect. 4" The Internet has become an important way to get and share information. We won't know the real effect of the differences between the Internet and other media for years. However, one thing is clear now. It has already become an essential part of our culture. 1» 2»
