Motherboard - a computer s main electronic printed circuit board. In many cases motherboards often have one or more expansion slots for adding capabilities to the computer at a later date. A term used to describe memory modules which are built with a brand of chip mounted on a board of the same brand. Non-parity memory leaves error checking up to external circuits which the motherboard may possess. Parity memory - memory that contains extra chips or logic to help detect bit errors which can cause data corruption or system crashes.
Simple parity checking memory can detect single bit errors and notify the user or halt the system.
ECC parity memory can detect multiple bit errors and correct single bit errors. Proprietary memory - A memory card or module designed for a specific computer system which does not conform to an industry standard form factor. RAM - Random Access Memory. A type of memory which can allow access to any cell in the memory as fast as any other cell by specifying that cells address. Refresh rate - DRAM chips used on memory modules must be refreshed to retain their contents.
