I have only one OS in my PC -- UBUNTU. I wish to double the RAM. So, if I got a table to verify the size of the swap area space, it would be very useful (without going deep into the details); especially for installation. I mean, the range for 1GB, 2GB, 4GB etc. If possible please tell me a preferable swap area for each.
I wish to know the minimum & preferable PERCENTAGE of space for Root "/" when the Hard Disk is considered.
