1. What is the difference between RAM and ROM?
RAM is volatile storage and is used to temporarily store data; while ROM is non-volatile storage, which can still save data after the device is turned off, and is usually used to store unchangeable data such as system startup programs.
-
2. What is embedded memory?
Embedded memory is a memory integrated into an electronic system for real-time data processing and program execution of the device. It is commonly found in microcontrollers, mobile devices, and embedded systems.
-
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. 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.
