Yes, 1024 is one gig, but often some memory is stolen by the motherboard ā for example if you have an on-board graphics card that uses main memory for its RAM.
Personally, if you can afford it and the 4G is less than 2x the 2G Iād get 4G ā but if you could find 2x2G sticks then you could have 6G total ā not bad IMHO.

I got a Dell dimension c521. It is slow so I figure I should add memory. There are 4 memory slots with 2 being used. How much memory is that? Well, the cards that are in there say it they are two cards with 1024 mb apiece. 'free -h' reports free -h total used free shared buffers cached Mem: 1.9G 1.4G 489M 18M 59M 535M isn't 1024 one gig?
