Overview
Flash memory is a type of non-viloate memory. This means that it can sustain it's data without power, like a hard drive. Flash memory comes it 2 types, NOR and NAND. NOR is optimized for storing things that will be executed (like programs), while NAND is optimized for data storage and is easier to make in higher capacities.[1] Flash memory in the form of USB flash dirves and solid state drives has become the primary physical way to transfer information from computer to computer. Here are the most common forms of Flash Memory

Significance
Flash memory has replaced floppy drives, and later CDs, as the main way to store information and transfer it between computers. Also, flash memory has almost etirely wiped out film in cameras.
