Question: how much bigger is a megabyte than a kilobyte?
Answer: A kilobyte equals 1000 bytes (actually 1024 bytes but we normally round it off). A megabyte equals 1,000,000 bytes. A gigabyte equals one billion bytes. For comparison, a standard 3 1/2 inch floppy disk holds 1.44 megabytes (1,440,000 bytes).
