Many services LISTENing (netstat output)

I have following output with command "netstat -putnl" as root (only LISTENing services shown):

Code: Select all
[root@localhost bin]# netstat -putnl

Do I need all these? I only need to browse the internet and print on a usb connected printer using this computer. I think I need cupsd for printer and hddtemp for disk temperature monitoring. What are the others for and can I remove them safely? If so, how can I remove them? Thanks for your help.
