When trying to make sense of the magnitude of very large numbers, it helps to remember that each "number name" is 1000 times more than the previous number name.

• 1 billion is 1000 times more than 1 million
• 1 trillion is 1000 times more than 1 billion

Although we listed the "byte system" as powers of 10, the same names are sometimes interpreted as powers of 2. This is especially true in computer programming because computers work on a "base 2" system. In that system, 1 kilobyte is considered to be 1024 bytes. The table at the right compares the two systems.
