Tobacco Use & Consequences. Smokeless tobacco use is back on the rise. The Federal Trade Commission's 2003 Report on smokeless tobacco states that, for the past three years of data (1999-2001), sales of smokeless tobacco (in pounds) has increased compared to a declining trend from 1991 to 1999.
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). A Zip disk holds 100 or 250 megabytes.
The prefix kilo, also used in the metric system, denotes 1024 bytes or a kilobyte. The number isn't exactly 1,000 because bytes are based off the binary system (0 and 1) where 2^10 = 1024. Megabytes versus Gigabytes. Megabytes and gigabytes, like the kilobyte, are magnitudes of bytes. Basically, a gigabyte is larger than a megabyte. The difference is similar to that between one billion and one million, respectively. For example, when you buy a computer with 500 GB, this means it can store approximately 500 billion bytes of information.
