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 are the main types of memory?
Common memory types include random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), and solid-state drive (SSD).
-
3. 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.

4. How to measure the data read and write speed of memory?
The read and write speed of memory is usually expressed in MB/s or GB/s, reflecting the amount of data it processes per second. The faster the speed, the higher the data transmission efficiency.
