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).

The diameter of VY Canis Majoris is Est. 3,063,500,000 km. (but disputed). If the Sun was replaced by VY Canis Majoris, its surface would extend to the orbit of Saturn.Assuming the upper size limit of 2100 solar radii, light would take more than 8 hours to travel around the star's circumference, as opposed to 14.5 seconds for our Sun.It would take over 7,000,000,000,000,000 (7 Quadrillion) Earths or 7,000,000,000 (7 Billion) Suns to fill VY Canis Majoris.Y Canis MAjoris is a star that is 2100 times the mass of our own sun, and it is the largest star discovered to date. 7 people found this useful.
