Answer: C - DIMM memory slots use a 64-bit data transfer bus.

Key Takeaway: A DIMM (dual in-line memory module) is a series of dynamic RAM integrated circuits. DIMM modules were designed for use in personal computers, servers, and workstations. DIMMs have overtaken SIMMs, which have only a 32-bit data path, as the predominant type of data module. Both RIMMs (Rambus in-line memory modules) and SO RIMMs (small outline Rambus in-line memory modules) are types of packaging for RDRAM, created by Rambus, Inc. RIMMs have a 64-bit transfer rate, while SO-RIMMs are significantly smaller and come in 32-bit and 64-bit models.
