M: How is school going, Barbara? Are you taking any new classes?
W: I’m taking another really interesting course called Business and the Web. We are learning about e-commerce and how new technological developments will affect the way we buy, sell and market things in the future.
M: Wow, that sounds like something I should take.
W: I think it’s one of the most useful courses I’ve had so far. Right now, we are studying wireless communications and how that’s going to affect the development of the internet and eventually online business. We have had several lectures on the importance of cell phones and several new kinds of portable computers and other electronic devices which are based on related technologies.
M: What other kinds of topics will you be covering?
W: We are going to discuss high bandwidth Internet connections, like cable modems, which will allow us to exchange information more quickly. And from there, we will focus on how Internet, TV, radio and telephone technologies are all starting to come together.
M: I was just reading about that in the newspaper. But how does that relate to online business?
W: As these technologies converge in the near future, a new high-speed network will develop which will be perfect for the distribution of products and services online.
