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). 

• Cactus spines are also known as modified bud scales, which are also called modified leaves.

• Cactus spines occur in clusters in the axil of leaves.

The Indian Institute of Technology (IIT) Kanpur will confer a doctorate on former sprint queen PT Usha, who missed a medal by a whisker at the 1984, Los Angeles Olympics. The degree, Doctor of Science (honoris causa – a degree awarded as a mark of esteem) will be conferred on June 16 to mark the 50th convocation of the prestigious institute of the country. This is her second doctorate – in 2002, Kannur University had conferred D.Lit on her.
