220-801 · Question #387
ECC memory is primarily used in which of the following computers?
The correct answer is C. Server. ECC (Error Correcting Code) memory is used primarily in servers because they require the highest levels of data integrity and cannot tolerate memory errors that could corrupt critical operations.

Why each option
ECC (Error Correcting Code) memory is used primarily in servers because they require the highest levels of data integrity and cannot tolerate memory errors that could corrupt critical operations.
Tablets use low-power mobile memory (LPDDR) optimized for efficiency and size, not ECC-grade memory.
Standard desktops use non-ECC DDR memory for cost and compatibility reasons; ECC is not a common desktop requirement.
Servers run continuously, handle critical workloads, and process large volumes of data where even single-bit memory errors could cause data corruption, system crashes, or security issues. ECC memory detects and automatically corrects single-bit errors and detects multi-bit errors, making it essential for server-class systems. The higher cost and slight performance overhead of ECC make it impractical for consumer devices like tablets, desktops, and laptops in most cases.
Laptops use standard SO-DIMM or soldered DDR memory without ECC support, prioritizing power efficiency and cost.
