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 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.
-
3. What is ECC memory?
ECC (error correction code) memory detects and corrects single-bit errors in stored data, improving the reliability of memory and is commonly used in servers and data centers.
-
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.
