1. What are the main types of memory?
Common memory types include random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), and solid-state drive (SSD).
-
2. 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.
-
3. What is SSD and how to distinguish it from HDD?
SSD (Solid State Drive) is a non-volatile storage device that stores data through flash memory. It has faster read and write speeds than HDD (Hard Disk Drive), no mechanical structure, and long life, but the price is relatively higher.
-
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.
