Themes in the book • Old problems in a new context • Adapting to new technology • More problems, more solutions • Global reach of the Net • Trade-offs & controversy
We’ve come a long way • First electronic computers – 1940s • 1991, the space shuttle had a 1 MHz computer onboard • First HDD by IBM - 1956
IBM’s 1st Hard Drive 1954 • These 50 stacked 24”-diameter platters could have held about 2 iTunes songs. (The total capacity was 5MB.)
Comparing microdrives with the 1st IBM hard drive: • A 1-inch 8GB platter holds more than 80,000 times as much data as a single 24-inch RAMAC platter. • An 8GB 1-inch drive holds 1,600 times as much data as RAMAC.
New technology creates new problems • PCs & floppy disks • Email • Increased storage, speed & connectivity resulted in databases • The Web, browsers & search engines • Online commerce • Cell phones
