1. What is double data rate (DDR) memory?
DDR memory is a RAM technology that can transmit data at both the rising and falling edges of the clock signal to increase the data transmission speed. There are multiple generations of DDR, such as DDR3, DDR4, DDR5, etc., each generation has higher speed and capacity and lower power consumption.

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.

4. What is the memory hierarchy in a computer?
The computer memory hierarchy includes registers, cache, main memory (RAM), secondary storage (such as HDD or SSD), and external storage (such as tape, optical disk) from speed to capacity, and each level has different storage and access speeds.
