Learning Points from lesson 1

I learnt quite a few things in lesson 1. At the start I did not know that the net was started in 1969 and only had 4 host nodes compared to the over 200 million this year. I also learnt that URL stands for universal resource locator. The powerpoint slides are very intereseting with a lot of pictures. I also was shocked that we got a change in teacher. I hope Mr Cheong 's teaching can be better than Mr Koh's as I did not understand a single thing about C++ even now.
I also did not knew that was actually so much search engines other than yahoo and google. But the made a mistake in the slides not to put China's biggest search engine, Baidu on the list. Actually both of China's biggest search engines souhu and baidu were not included. For a chinese, this is unacceptable. There is so many plugins required mentioned that I began to download everything onto my laptop and making it so slow. But I won't get frustrated again and again for reminders of downloading.
In conclusion, I think that the internet is a useful tool in our daily lives and we can't live without it, but for the good purposes.
