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 flash memory and what are the common types of flash memory?
Flash memory is a non-volatile memory used to store data, and the data will not be lost even if the device is powered off. Common types are NAND and NOR flash memory, which are mainly used in USB flash drives, SSDs, memory cards, etc.
-
3. 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.
-
4. 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.
