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.
If the USB flash drive is being used with a computer, then it is assigned a drive letter by the computer just like any other type of attached drive and files can be read from or written to the USB flash drive until it is unplugged from the USB port. The capacity of most USB flash drive today ranges from 1 GB to 64 GB.
