Yet, another extended meaning of INFORMATION The UNIT of INFORMATION

Key element/basic resource INFORMATIONInformation ENERGYIndustrial FOODAgricultural Key elementSociety (Source: Everett M. Rogers, [ 1986 ], “ Communication Technology”, page. 13)‏

Key element/basic resource INFORMATION ENERGY FOOD Key element UNIT kg, lbs, liter, oz kWh, Joule,......barrel ???????

The SMALLEST UNIT of INFORMATION The SIMPLEST FORM of INFORMATION 10

The VALUE of an INFORMATION 10

The VALUE of an INFORMATION

The VALUE of an INFORMATION

0000 could differ up to 2 n things: The VALUE of an INFORMATION

American Standard Code for Information Interchange a b c d e x y z A B C D E F G H Z a = b = Z = H = \ = h = The VALUE of an INFORMATION

How much information is in a 275-page book ???? 275 pages X 40 lines/page in average X 10 words/line in average X 5 characters/word in average X The VALUE of an INFORMATION

Larger units of INFORMATION 1 Kb 1 Kilobit 1000 bit 1 Mb 1 Megabit 1000 Kb 1 Gb 1 Gigabit 1000 Mb 1 Tb 1 Terrabit 1000 Gb = 8 s/d 10 bit 1 B 1 Byte

Larger units of INFORMATION Example: A flashdisk has a capacity of 8 Gb. How many e-books of 5.5 Mb can be stored in the flashdisk?

Larger units of INFORMATION Answer: The flashdisk has the capacity of 8 Gb = 8000 Mb. The e-book's “size” is 5.5 Mb. Thus, the flashdisk can be filled up to 8000/5.5 e-books, or around 1455 e-books ! (Compare to your bag, how many books can you store in it??? 5, 6, books?)
