A technician is upgrading RAM in a thin laptop and needs a memory module in the correct compact form factor. Which type of RAM module should the technician use?
- ASATA
- BSODIMM
- CM.2
- DDIMM
Show answer & explanationAnswer & explanation
Correct answer: B. SODIMM
SODIMM (Small Outline Dual In-line Memory Module) is a compact RAM form factor designed for laptops and other small devices, while DIMM is the larger standard used in desktops. SATA is a storage interface, and M.2 is a storage/expansion card slot, not a RAM standard.
Why the other options are wrong
- A. SATA is an interface for connecting storage drives, not RAM.
- C. M.2 is a slot for SSDs or wireless cards, not standard RAM.
- D. DIMM is the full-size RAM module used in desktop computers.
SODIMM
A compact memory module form factor used in laptops and small-form-factor devices, smaller than desktop DIMM modules.
- Roughly half the length of a DIMM
- Used in laptops, mini PCs, printers
- Not interchangeable with desktop DIMM slots
Memory trick: SODIMM is DIMM's 'So' Small cousin for laptops.
