After the defeat of china by Japan in a war over Korea in 1894,France, Russia, Britain and Germany gave loan to china to help it to the payment of 150 million dollors demanded by japan.

          The united states feared that china would be completely parcelled out in exclusive 'spheres of influence' and that its trade with china would be shut off. The USA, therefore, suggested the policy known as the "Open Door". This policy is also described as "Mee too Policy".

DRAM is a Volatile random-access memory (VRAM).

Volatile random-access memory (VRAM) is random-access memory that retains its information when power is turned on.

Examples of volatile memory are primary storage (typically dynamic RAM, DRAM), and fast CPU cache memory (typically static RAM, SRAM, which is fast but energy-consuming and offer lower memory capacity per area unit than DRAM).

Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off.

Examples of non-volatile memory are flash memory (used as secondary memory) and ROM, PROM, EPROM and EEPROM memory (used for storing firmware such as BIOS).
