count with select distinct?

[Ben Huntsman]

Hi there!
SQL's not my strong suit, but I'm trying to learn a thing or two, but this case has me stumped. Let's say I have a table like this (pardon the formatting):

software version computer location
----------------------------------------------------------------------
1 2805 150 somewhere
1 2805 1866 somewhere
2 2 137 somewhere
2 2 150 somewhere
2 2 550 somewhere

Now, I want to return two results columns, one for the software, one for the count of computers. As you can see in the table, there are multiple rows, one for each computer id number, but the software id number is repeated. So basically, I'm after a result set that looks like this:

software installedcount
------------------------------------------
1 2
2 3

Anyone know how to pull that off?

Many, many thanks in advance!!
