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 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.
-
3. What is the difference between SRAM and DRAM?
SRAM (static RAM) does not require periodic refreshes and is faster but more expensive; DRAM (dynamic RAM) requires periodic refreshes and has a higher storage density and is suitable for main memory.
-
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.
