1. 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).
-
2. 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.
-
3. 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.
-
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.
