16 16 Data vs. Information Data vs. Information:Data vs. Information: –Data is a representation of a fact or idea NumberNumber WordWord PicturePicture SoundSound –Information is data that has been organized or presented in a meaningful fashion.

17 17 Computers are Data Processing Devices Four major functions:Four major functions: –Input data –Process data –Output information –Store data and information DATA IN INFORMATION OUT

18 18 Bits and Bytes: The Language of Computers BitBit –Binary digit –0 or 1 ByteByte –Eight bits ASCIIASCII –Each byte represents a letter, number or special character OFF 0 ON 1 Microchip Switch = = A 0

19 19 How Much is a Byte? NAMEABBREVIATIONNUMBER OF BYTES RELATIVE SIZE ByteB 1 byteCan hold one character of data. KilobyteKB 1,024 bytesCan hold 1,024 characters or about half of a typewritten page double-spaced. MegabyteMB 1,048,576 bytesA floppy disk holds approximately 1.4 MB of data, or approximately 768 pages of typed text. GigabyteGB 1,073,741,824 bytesApproximately 786,432 pages of text. Since 500 sheets of paper is approximately 2 inches, this represents a stack of paper 262 feet high. TerabyteTB 1,099,511,627,776 bytesThis represents a stack of typewritten pages almost 51 miles high. PetabytePB 1,125,899,906,842,624 bytes The stack of pages is now 52,000 miles high, or about one-fourth the distance from the Earth to the moon.
