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 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. 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.
