>From root use the following commands

To check the cpu details you can you the command = cat /proc/cpuinfo

To check the disk size use the command = fdisk -l or df

To check the memory size use the command = cat /proc/meminfo

If you are not getting any response for rpm -q for apache use command
= rpm -q httpd
it will show the if apache is loaded and which version of apache is

Not sure about 5th question. if you get any answer lemme know.

To uninstall you can use the command rpm -e packagename.

If you want to upgrade any package use command rpm -Uvh packagename.

Hope this helps.....
