Are you referring to the "workspace" as posted above
the toolbar at the bottom of the screen has ether 2 or 4 "workspace" on it ( bottom right next to the clock)
A "workspace" is a virtual desktop , and has been part of linux and apples mac for almost forever .
They DO come in very handy ,but you can disable it if you want .
My Belkin N150 adapter isn't working at all, how can i get this to work so i can actually use my internet?
cent like Red Hat is foremost designed for a server in a server room ,and not for home use
Now it can and is used on home desktop computers
I DO NOT
use my install of Scientificlinux 6.3 for everyday use ( i use OpenSUSE 12.1 for that )
-- it is NOT the best tool for that job --
i use it for running scientific lab software --
it is a VERY good choice as a tool for that --
with cent being a free rebuild of RHEL 6.3 it is a very manual operating system
you need to set up and configure most things
CentOS dose add in programs for better use on a home system , but....
being designed primarily for a server wireless support is , well, lacking
see the centos wiki
as to your "Belkin N150 adapter"
this cent forum post
see this ubuntu howto
you will need to transpose the ubuntu instructions into red hat instructions
cent dose NOT use "sudo" by default
