Sorting categories into different pages

I want to have multiple pages on my front page but in each page I want different categories of posts listed.

Ex.
When I talk about Windows I want to put it in the Windows category and have it show up on my windows page

when I talk about Mac assign it the Mac category and have it show up only when someone clicks on the Mac page

and so on like that.. Currently all posts show up on one page no matter what the category is. how can I fix this.
