- Sorting out the differences in system RAM
- Over the years, IT pros have seen different technologiescome and go--and some that just stubbornly refuse to die (floppy drives,anyone?). One area that's changed drastically over the years is memory. FromSIMMs to DIMMs to EDO to Rambus,RAM has come in all shapes and sizes and is definitely not a "one...
