Memory Error Correction — CompTIA A+ Core 1 (220-1101) Practice Questions

Memory error correction refers to technologies built into RAM modules that detect and fix data errors caused by electrical noise, cosmic rays, or hardware faults. ECC (Error-Correcting Code) memory uses extra bits to identify and correct single-bit errors on the fly, while parity memory can only detect errors without correcting them. On the 220-1101 exam, you need to know when ECC is appropriate (typically workstations and servers handling critical data) versus standard non-ECC consumer RAM, and which platforms and chipsets support it.
