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).

Normality is a way of expressing concentration of a solution and can be calculated by the formula-

Normality (N) = No. of gram equivalent of solute/ volume of solution (in litre)

Gram equivalent weight of H2 SO4 = Molecular weight/ No. of Hydrogen atom = 98/2 = 49 gm

No. of gram equivalent in 49 gm of H2 SO4 = 1

So, Normality in 1 litre of solution = 1/1 = 1 N

“Rashtriya Vayoshri Yojana” was launched by the Ministry for Social Justice and Empowerment on 1 April 2017 at Nellore (Andhra Pradesh). Under the scheme, physical aids and assisted-living devices for senior citizens were distributed to senior citizens belonging to below poverty line (BPL) category.

– The scheme has been implemented through the sole implementing agency – Artificial Limbs Manufacturing Corporation (ALIMCO), a public sector undertaking. The aids to be distributed under the “Rashtriya Vayoshri Yojana” scheme include walking sticks, elbow crutches, walkers, tripods / quadpods, hearing aids, artificial dentures and spectacles.

– The ambitious scheme, first of its kind in the country, is expected to benefit 5,20,000 Senior citizens over a period of the 3 years.
