Computer Literacy Anthony J. Nowakowski, Ph.D. Magnified x 2,500 CD-ROM

Computer Literacy Anthony J. Nowakowski, Ph.D. One CD-ROM can store up to 650 megabytes which is about the same amount of data as:

Computer Literacy Anthony J. Nowakowski, Ph.D.  260,000 pages of text  19,000 pages of images 300 x 300 dpi  74 minutes of video  74 minutes of CD quality sound  465 high density 3.5” diskettes  90 hours or almost 4 days at 28,800 baud

Computer Literacy Anthony J. Nowakowski, Ph.D. So what can be done with this enormous capacity?

Computer Literacy Anthony J. Nowakowski, Ph.D. WASHINGTON - Until recently, the government’s $50 million monthly phone bill ran to more than a million pages and ended up boxed in a southern Illi- nois warehouse. But in a development both marvelous and omi- nous, those bills are now available on six shiny CD-ROM discs. Government bosses and investigators can identify in 18 seconds - and without a court order - the date, time, and duration of every long distance call made from hundreds of thousands of federal phones. Text only By FRANK GREVE Knight-Ridder TELEPHONE RECORDS

Computer Literacy Anthony J. Nowakowski, Ph.D. America’s phonebook on CD-ROM Over 81 million listings on five CD-ROMs. Find anyone, anywhere as quickly as you can type in a name, address, or even phone number. You can get a complete listing with phone number, address, city, state, and zip code. You can then auto dial the number or print out a list or even mailing labels. $28.95 Text only

Computer Literacy Anthony J. Nowakowski, Ph.D. As of last year, DVD’s are now being sold. They store data seven times more densely than CD-ROM’s and on both sides. 650 megabytes x 14 = 9.1 gigabytes!

Computer Literacy Anthony J. Nowakowski, Ph.D. This is accomplished by using a higher density.
