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