The Lego Building Blocks

Imagine you're building with Lego. A single brick (bit) is tiny. Eight bricks make a small block (byte - enough for one letter). 1,024 small blocks make a bag (kilobyte - a short email). 1,024 bags make a box (megabyte - a photo). 1,024 boxes make a crate (gigabyte - a movie). 1,024 crates make a shipping container (terabyte - your entire photo library). Each level is roughly 1,000× bigger than the last!
