Computer Hardware Flashcards
What does NVMe stand for and what is it?
Non-Volatile Memory Express, or NVMe, is a new specification optimized for NAND flash and next-generation solid-state storage technologies or Hard Drives.
While CPU and DRAM speeds have increased over time, mechanical hard drives and the interface to them have not. NVMe closes the gap between fast DRAM and the systems storage.
What is NAND Flash?
NAND flash is the controller that managers all non-volatile storage architectures such as USB, Flash drives, and SD cards
NAND gets its name from the type of the logic gate (NOT-AND) and is used to determines how digital information is stored in a flash device’s chips, Wear Leveling and Error Correction.
What is ECC memory and NON-ECC memory? Which is better?
ECC memory or Error Correcting Code gives RAM the ability to detect mistakes that may occur in data memory without the need to consume separate computing resources.
ECC results in about 2% lag compared to non-ecc, and as DRAM is incredibly stable, usually, we use non-ECC
Side note: ECC Has memory modules have a chip count divisible by three or five that you can see on the physical chip. So its possible to know if memory is ECC or non-ecc by lookning at it!
What’s the difference between DVI-D and DVI-I?
DVI-D is Digital Only while DVI-I supports both Digital Signals and is backwards compatible with Analog Signals as well
Can DVI carry an audio signal?
No
