You have been tasked with recommending memory upgrades for your organization’s laptop computers. What memory form factor is often seen in laptop computers?
The answer: D) SO-DIMM
The small outline dual inline memory module is about half the length as a normal DIMM, making it a perfect choice for laptop manufacturers who prefer to save space in a laptop form factor.
The incorrect answers:
Single in-line memory modules were one of the early standard memory packages for personal computers.
The dual in-line memory module is the standard memory module form-factor used in most desktop personal computers today. DDR SDRAM, DDR2 SDRAM and DDR3 SDRAM use different styles of the DIMM form-factor to provide modular memory installations. Unfortunately, the DIMM form-factor is too large for portable use and isn’t used for laptop systems.
The Rambus inline memory module was created by the Rambus Corporation. The module sizes were similar to DIMMs, making them impractical for laptop use.

The CompTIA A+ certification requires extensive knowledge of memory packages, pin counts, and memory functions. In this module, we’ll step through each memory package and describe the progression of the different memory types through the years. We’ll discuss packages such as DIMM, RIMM, SODIMM, and MicroDIMM, and we’ll also detail memory types such as SRAM, SDRAM, RDRAM, DDR, and DDR2.
