1. 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.
-
2. 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.
-
3. How to upgrade the computer's memory?
Computer storage performance can usually be improved by adding RAM modules or upgrading the HDD to a faster SSD. It is also necessary to ensure that the new hardware is compatible with the system, especially motherboard support and memory type.
-
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.
