Cache, it is very fast normally around 1.4 giga hertz. |
|
|
2)What is the difference between DRAM and SRAM? |
DRAM is used for storing programs whilst the are being used such as windows, they are quite large for RAM normally at about 8GB, where as SRAM is used as cache memory, it is stupidly fast and is used for the processor to transfer items and store them for processing. |

3)What is the difference between Solid state drives and hard disk drives? |
solid state drives use a series of integrated circuits as storage for data, it is robust, fast, light, more efficient but expensive. hard disk uses a lot of disks and an arm that uses magnetism to extract data, vunerable, slow, heavy, power hungry. |
