• (1) Executable programs or shell commands eg. ls, cp
• (2) System calls (we will be looking at many of these in the coming weeks)
• (3) Library calls eg. strcpy, scanf
• And other sections we won't be using much

You can find the full table by using the command man man which shows the manual page about the manual.

You can get more information about individual sections by using man 1 intro, man 2 intro etc.

Advice: man will be available in the exam. Google will not! Get used to using it!
