And in case someone want to know what the output to 'uptime' means. The fields are as follows.

1) Current time
2) The current uptime (i.e. time since last reboot)
3) Load Averages for the last 1 min, 5 min, and 15 min

And Load Average is a measure of how busy a system is. Technically it's the the number of processes that are on the run queue. That is processes that are ready to actually do some work.
