1. What is flash memory and what are the common types of flash memory?
Flash memory is a non-volatile memory used to store data, and the data will not be lost even if the device is powered off. Common types are NAND and NOR flash memory, which are mainly used in USB flash drives, SSDs, memory cards, etc.

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 the memory hierarchy in a computer?
The computer memory hierarchy includes registers, cache, main memory (RAM), secondary storage (such as HDD or SSD), and external storage (such as tape, optical disk) from speed to capacity, and each level has different storage and access speeds.
-
4. 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.
