1. Is there a relationship between the capacity and speed of memory?
The capacity and speed of memory are not directly related. The capacity refers to the amount of data that the memory can hold, while the speed determines the speed at which the memory reads and writes data. Generally speaking, faster memory such as RAM has a smaller capacity, while large-capacity storage such as HDD is relatively slow.
-
2. What are volatile and non-volatile memory?
Volatile memory loses data when power is off, such as RAM; non-volatile memory retains data after power is off, such as ROM and flash memory.

3. 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.

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.
