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.
USB flash drives are small drives (usually about a half inch wide by 3 inches long) that can store very large amounts of information. As of 2009, high-end flash drives can hold 128 gigabytes, and smaller ones (2 to 8 GB) are inexpensive and commonly available. That has allowed quite large amounts of data to be stored very easily and portably â and, due to the prevalence of USB (Universal Serial Bus) sockets, with near-universal accessibility.
