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. 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.
-
3. 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.

4. What is High Bandwidth Memory (HBM) and what are its advantages?
HBM is a high-bandwidth, low-latency memory technology commonly used in graphics cards and AI accelerators that can handle a large number of parallel computing tasks. HBM's stacked architecture makes it take up less space and more efficient, making it an ideal choice for big data and high-performance computing applications.
