CompTIA A+ Core 1 (220-1201)HardwareHard
A technician is evaluating memory modules for a new server build that requires enhanced data integrity. Which type of RAM is specifically designed to detect and correct common memory errors, making it ideal for critical server applications?
- ASODIMM
- BECC RAM
- CNon-ECC RAM
- DDDR5 DIMM
Show answer & explanationAnswer & explanation
Correct answer: B. ECC RAM
ECC (Error-Correcting Code) RAM is specifically designed for servers and workstations where data integrity is paramount. It includes extra bits that allow it to detect and correct single-bit memory errors, preventing system crashes and data corruption that could occur with standard (non-ECC) RAM. While DDR5 is a generation of RAM, and SODIMM is a form factor, ECC refers to a critical feature for reliability.
Why the other options are wrong
- A. SODIMM (Small Outline Dual In-line Memory Module) is a form factor for laptops and compact devices, not a feature related to error correction.
- C. Non-ECC RAM lacks the error detection and correction capabilities of ECC RAM, making it unsuitable for critical server applications where data integrity is paramount.
- D. DDR5 DIMM refers to the generation and form factor of the RAM, but it doesn't inherently imply error correction. DDR5 can be ECC or non-ECC.
ECC RAM
Error-Correcting Code (ECC) RAM is a type of computer memory that can detect and correct the most common kinds of internal data corruption.
- Crucial for servers and workstations requiring high data integrity and uptime.
- Uses parity bits and algorithms to identify and fix errors.
- Requires a motherboard and CPU that support ECC memory.
