OS Next Week (& the rest of this semester)

Next week, we will proceed to Chapter 5 "Input/Output." It is expected to cover first two or three sections (i.e. Section 5.1 to 5.2 or 5.3 if possible).

For the rest of this semester, we will cover sections 5.1 to 5.4 and 5.8, for various reasons, including the time limitation, our school's curriculum background and relative significance of the topic in each section.

Again, please be prepared before coming the class. Knowing what you don't know or what you feel hard to understand is very important.
