I used the command 'top' to show running processes, and I noticed the first and second line look like this:
top - 00:30:31 up 5:41, 3 users, load average: 0.14, 0.16, 0.27
top - 00:31:25 up 5:42, 3 users, load average: 0.38, 0.20, 0.28
When I first noticed it, it said 4 users. My question is what does it mean by "3 users" or "4" users?
