    Note: Sleep is attended by a relaxation of the muscles, and
          the absence of voluntary activity for any rational
          objects or purpose. The pulse is slower, the
          respiratory movements fewer in number but more
          profound, and there is less blood in the cerebral
          vessels. It is susceptible of greater or less intensity
          or completeness in its control of the powers.

Computing Dictionary
 
 Definition: 

1. (Or "block") When a process on a multitasking system asks the scheduler to deactivate it until some given external event (e.g. an interrupt or a specified time delay) occurs.

The alternative is to poll or "busy wait" for the event but this uses processing power.

Also used in the phrase "sleep on" (or "block on") some external event, meaning to wait for it.

E.g. the unix command of the same name which pauses the current process for a given number of seconds.

2. To go into partial deactivation to save power.
