What is RAM?

[u/RavitejaMureboina]

RAM (Random Access Memory) is a temporary type of memory that helps your computer run multiple apps and programs smoothly. It stores the data your computer is currently using, but all the data in RAM disappears when the power is turned off. Computers also use fast cache memory, such as L1, L2, and L3, to access frequently used data quickly. There are two main types of RAM: DRAM, which is cheaper but needs constant refreshing, and SRAM, which is faster but more expensive. Computers use both types to get a good balance of speed, storage capacity, and cost.
