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 are volatile and non-volatile memory?
Volatile memory loses data when power is off, such as RAM; non-volatile memory retains data after power is off, such as ROM and flash memory.
-
3. What is the difference between cache and RAM?
Cache is a high-speed memory between the CPU and the main memory, which is used to temporarily store data and instructions commonly used by the CPU to speed up the system. RAM is the main storage of the system, which is used to store data for applications and operating systems.
-
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.
