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 choose the right memory type?
When choosing a memory type, you need to consider speed, capacity, durability and cost according to application requirements. For example, SSD is suitable for data that needs to be accessed quickly, HDD is suitable for large-capacity data storage, and RAM is suitable for high-speed computing.
-
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. Why is the DRAM refresh rate important?
DRAM needs to be refreshed regularly to maintain data. The refresh rate affects the power consumption and speed of the memory. The higher the refresh rate, the faster the memory responds, but it also increases power consumption.
