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. 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.
-
3. What is virtual memory and how does it work?
Virtual memory is a technology that uses hard disk space as memory, allowing the system to use hard disk space to expand memory when physical RAM is insufficient, improving the system's multitasking capabilities.
-
4. How to extend the life of memory devices?
Measures such as regular data backup, avoiding excessive reading and writing of memory, ensuring proper temperature control, and preventing power fluctuations can help extend the life of memory.
