sql count based on key id

P: 1
I have 2 tables both have a primary key which links them,

How can I run a count query to look at the first table and check the id, then look at the second table and count up how many records have that same id?

table one
key - software_make
1 Adobe
2 Microsoft

table two

key - asset - Number_installed
2 11454 1
2 1245 1

so the result im looking for would show

Microsoft with number installed as 2

Hope this makes sense,

Join the two tables and use the aggregate count() grouping by the maker.
