256mb of ram is absolutely crap and hopeless and 512mb of ram will barely make a difference so if i were you i would go for at least 2gigabytes of ram.
well it would depend on what kind of RAM your computer uses and what type you want. but from what i know a 1 GB ram stick will cost around $24 give or take depending on where you go
1 byte = 8 bits 1 kilobyte (kB) = 1024 bytes1 megabyte (mB) = 1024 kB1 gigabyte (gB) = 1024 mBBasically, the 1024 comes from computers using the binary system
If you have enough memory slots, generally yes. But it depends on the age and capacity of the computer.
