week 5

This week we have a midterm. It was all about reviewing the materials that we learnt from previous weeks, such as the history of computing devices, and the functions. I found that the most interesting part of this course is to use DrRacket to define functions that we learnt in class. It gives me a lot accomplishments when I actually can define a function correctly.

When I learning the history of computers, I found that some of the facts are really similar to each other. I am not very familiar with most of the content, so I needed to open many links on the website to get more information about those inventions. It's easier to understand the history than just memorizing it.

The test is not hard. Actually the binary part is what I didn't know before. But I realize it when I did the past test and I called my friend who took this course last year. He taught me about it and there is a question about that. So I was very glad that I learnt it before the test.
