RAM stands for random-access memory, which makes it possible to find specific information very quickly. It is a form of fast-access, volatile storage that is used as the main memory in computer systems. The most widely used form of RAM for the main memory is dynamic RAM (DRAM).

VY Canis Majoris. Estimates of the star's radius range from around 1,500 to 2,000 times larger than the sun, if VY Canis Majoris was placed in the center of our solar system it would reach the orbit of Saturn! VY Canis Majoris is estimated to have a mass of around 20 to 40 times that of the sun.VY Canis Majoris is estimated to have surface temperatures of around 3,200C (5,800F). Measurements of the star's luminosity vary quite dramatically, from around 250,000 to 500,000 times as luminous as the sun.Y Canis Majoris is estimated to have a mass of around 20 to 40 times that of the sun.
