1. What is memory and what does it do?
Memory is a computer component that stores data and instructions. It can be temporary (volatile storage) or permanent (non-volatile storage) and is used to support system operation and data storage.
-
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. How to upgrade the computer's memory?
Computer storage performance can usually be improved by adding RAM modules or upgrading the HDD to a faster SSD. It is also necessary to ensure that the new hardware is compatible with the system, especially motherboard support and memory type.

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.
