1. What is the difference between RAM and ROM?
RAM is volatile storage and is used to temporarily store data; while ROM is non-volatile storage, which can still save data after the device is turned off, and is usually used to store unchangeable data such as system startup programs.
-
2. What is SSD and how to distinguish it from HDD?
SSD (Solid State Drive) is a non-volatile storage device that stores data through flash memory. It has faster read and write speeds than HDD (Hard Disk Drive), no mechanical structure, and long life, but the price is relatively higher.
-
3. What is ECC memory?
ECC (error correction code) memory detects and corrects single-bit errors in stored data, improving the reliability of memory and is commonly used in servers and data centers.

4. What is High Bandwidth Memory (HBM) and what are its advantages?
HBM is a high-bandwidth, low-latency memory technology commonly used in graphics cards and AI accelerators that can handle a large number of parallel computing tasks. HBM's stacked architecture makes it take up less space and more efficient, making it an ideal choice for big data and high-performance computing applications.
