Text: As an aid in understanding some of the jargon used in discussing RAM upgrades, here are some commonly used terms: SIMMs -- Single inline memory modules, the chips that provide the memory. RAM -- Random access memory, the Mac's temporary memory. When you turn off your Mac, the data in the RAM is gone. Surface mount or low profile -- One of two sizes of SIMMs. These are more popular since they take up less room in the Plus and SE. Dual in-line package (DIP) or high profile -- These are cheaper, but they also take up more room. If you have other internal hardware, such as accelerator boards or hard disks. Since the Mac II has more room, it may be more economical to use these. Nanoseconds -- The unit of measurement in determining the speed of the SIMM. The lower the number, the faster, but you often get more speed than the stated number. The Plus and See require 150 nanosecond or fasterl; the II needs 120 or faster. Motherboard -- The board on which you install the RAM chips.
