Newton's Theory of Gravity states that every object in the universe pulls on every other object. Every object feels this force, so it is a universal force. The force is always attractive; it is always a pull, never a push. Picture the force of gravity as the tension in an imaginary rope between two objects.
The whole point of a USB drive is to store lots of data in a small space, so think about what kinds of files you'll want to house on your flash drive. Movies and music take quite a bit of space, so if you're carrying your whole entertainment library with you, you'll want a big thumb drive â at least 16GB.
A USB flash drive is a compact, rewritable, data storage device that connects to a computer through a Universal Serial Bus (USB) interface. These drives can be as small as 128 MB, and as large as 256 GB, and researchers are even looking at ways to increase that capacity up to 2 TB.
