CompTIA A+ 220-901

Answer: C - Parity memory uses 8 bits to store a byte of data plus one bit for parity; 9 bits per byte. To store 8 bytes of data, parity memory uses 72 bits.

Key Takeaway: A DIMM (dual in-line memory module) is a DRAM (dynamic random access memory) module comprised of integrated circuits and designed for use in personal computers, workstations, and servers. Multiple DIMMs may be mounted on a printed circuit board.
