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). 

Megahertz is used to measure wave frequencies, as well as the speed of microprocessors. One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed.

 O @ N # M means O is the father of N who is the sister of M i.e. O is a father of two children.

Ans. 
Distance covered by 1st train in 4 hours = 80*4 = 320 km
Relative speed of 2nd train = 120-80 = 40 km
It will overtake another train in 320/40 = 8 hours
Distance between overtake point and station A = 8*120 = 960 km

India’s first multi-modal electric vehicle project has been inaugurated by the Union Road Transport and Highways Minister Nitin Gadkari, along with Maharashtra Chief Minister Devendra Fadnavis at the Nagpur Airport Complex to promote eco-friendly transport. With this, Nagpur became the first city in India to have electric mass mobility system with a fleet of 200 electric vehicles, including taxis, buses, e-rickshaw and autos.
