Great posts!! I definitely have to use these in my next Info Tech talk at my company...I work with a lot of low tech people that have trouble relating to size.

Have you seen the Did You Know video on the web yet? Check out http://www.youtube.com/watch?v=xHWTLA8WecI Some interesting numbers presented in this video.

COMPUTER TALK: Ever wonder how big a mb is vs a kb, etc.

I am through Computer 101 and to get momentum going it's good to know the basic foundation: CHECK THIS OUT!! How Much Data Is That? Note: The information shown below uses measures only associated with data. For example, a kilo-anything is 1000 . . . except that when it is a kilobyte, it is 1024, an even power of two. more at: http://www.jamesshuggins.com/h/tek1/two_or_ten.htm Whenever we discuss quantities of data, we tend to do it in the abstract. We speak of a kilobyte, or a megabyte or a gigabyte without really knowing what it represents. The following table shows various quantities of bytes, in each power of ten. Usually, they are shown with multiples of 2 and 5 also. For example, 1 Kilobyte, 2 Kilobytes, 5 Kilobytes. All the examples are approximate and are rounded. For example, a computer card has 80 columns. If 50 columns contain data on a card, then two cards will be 100 bytes. Also, a 3-1/2 inch diskette can contain 1.4 Megabytes. Showing it as 1 Megabyte reflects both (a) the diskette not typically being filled and (b) rounding. Finally, a CD-ROM can hold more than 500 Megabytes. However, it is listed at that level as "typical" and as the closest match. Bytes (8 bits) 0.1 bytes: A single yes/no decision (actually 0.125 bytes, but I rounded) 1 byte: One character 2 bytes: 5 bytes 10 bytes: One word (a word of language, not a computer word) 20 bytes: 50 bytes: 100 bytes: Telegram; two punched computer (Hollerith) cards 200 bytes: 500 bytes: Kilobyte 1,024 bytes; 210; approx. 1,000 or 103 1 Kilobyte: Joke; (very) short story 2 Kilobytes: Typewritten page 10 Kilobytes: Page out of an encyclopedia 20 Kilobytes: 50 Kilobytes: Image of a document page, compressed 100 Kilobytes: Photograph, low-resolution 200 Kilobytes: Two boxes (4000) punched computer (Hollerith) cards 500 Kilobytes: Five boxes, one case (10,000 of punched computer (Hollerith) cards Megabyte 1,048,576 bytes; 220; approx 1,000,000 or 106 1 Megabyte: Small novel; 3-1/2 inch diskette 2 Megabytes: Photograph, high resolution 5 Megabytes: Complete works of Shakespeare; 30 seconds of broadcast-quality video 10 Megabytes: Minute of high-fidelity sound; digital chest X-ray; Box of 3-1/2 inch diskettes 20 Megabytes: Two boxes of 3-1/2 inch diskettes 50 Megabytes: Digital mammogram 100 Megabytes: Yard of books on a shelf; two encyclopedia volumes 200 Megabytes: Reel of 9-track tape; IBM 3480 cartridge tape 500 Megabytes: CD-ROM Gigabyte 1,073,741,824 bytes; 230; approx 1,000,000,000 or 109 1 Gigabyte: Paper in the bed of a pickup; symphony in high-fidelity sound; broadcast quality movie 2 Gigabytes: 20 yards of books on a shelf 5 Gigabytes: 8mm Exabyte tale 10 Gigabytes: 20 Gigabytes: Audio collection of the works of Beethoven; five Exabyte tapes; VHS tape used to store digital data 50 Gigabytes: Library floor of books on shelves 100 Gigabytes: Library floor of academic journals on shelves; large ID-1 digital tape 200 Gigabytes: 50 Exabyte tapes Terabyte 1,099,511,627,776 or 240; approx. 1,000,000,000,000 or 1012 1 Terabyte: Automated tape robot; all the X-ray films in a large technological hospital; 50,000 trees made into paper and printed; daily rate of EOS (Earth Orbiting System) data (1998) 2 Terabytes: Academic research ligrary 10 Terabytes: Printed collection of the U. S. Library of Congress 50 Terabytes: Contents of a large mass storage system Petabyte 1,125,899,906,842,624 bytes or 250 approx. 1,000,000,000,000,000 or 1015 1 Petabyte: 3 years of EOS data (2001) 2 Petabytes: All U. S. academic research libraries 20 Petabytes: 1995 production of hard-disk drives 200 Petabytes: All printed material; 1995 production of digital magnetic tape Exabyte 1,152,921,504,606,846,976 bytes or 260 approx. 1,000,000,000,000,000,000 or 1018 5 Exabytes: All words ever spoken by human beings. Zettabyte 1,180,591,620,717,411,303,424 bytes or 270 approx. 1,000,000,000,000,000,000,000 or 1021 Yottabyte 1,208,925,819,614,629,174,706,176 bytes or 280 approx. 1,000,000,000,000,000,000,000,000 or 1024 :-) Kathy
