Well, it depends on the distro you are using. I am sorry but I cannot see what distrubtion you are using.
For updates and OS upgradation the best place to look is the distros website.
Hope this helps.

Generally, you would use the distribution's package management tools to see (a) what versions of softweare are installed and (b) if any updates are available. If you've installed any software outside the package management system, you'd have to check that individually (e.g. on the home page of each particular package).

from your other posts you are using RHEL6
a not free OS. One that REQUIRES a paid for support contract

once you are registered then it is easy
su -
-- your root password when asked for ---
yum update
and that is it

if you are NOT going to buy the required license then do not use RHEL
you will basically NOT be able to install much

then install the FREE OS CentOS 6.2
ScientificLinux 6.2

both are free rebuilds of RHEL
