Zorluk: KolayRAM Types and Characteristics

A technician is tasked with selecting replacement memory modules for a high-reliability portable workstation laptop. The system requires protection against single-bit memory errors and must fit the compact internal motherboard slot footprint. Which TWO of the following memory characteristics or form factors should the technician choose? (Select TWO)

  1. SO-DIMM form factorCevap
  2. ECC (Error-Correcting Code) functionalityCevap
  3. C
    Standard 288-pin full-sized DIMM form factor
  4. D
    Non-ECC unbuffered modules installed in adjacent non-alternating slots

Cevap

The technician must select SO-DIMM modules to match the physical laptop form factor and ECC functionality to provide required memory error detection and correction.
Laptops require SO-DIMM modules due to strict internal space limitations. High-reliability systems requiring protection against memory corruption mandate ECC (Error-Correcting Code) memory to identify and fix single-bit errors automatically.

Adım Adım Çözüm

1
Determine the required physical memory form factor for laptop hardware.
Laptops use SO-DIMM (Small Outline Dual In-line Memory Module) slots due to space constraints.
Desktop-class full-sized DIMMs cannot physically fit into laptop memory slots.
2
Identify the memory feature needed for single-bit error protection.
ECC (Error-Correcting Code) memory provides real-time detection and correction of single-bit errors.
Non-ECC memory lacks the extra data bits and logic required to check and correct memory errors.
