Enabling Information Technology - Empowering Moore's Law
Based on the insight of Intel co-founder Gordon E. Moore, Moore’s Law describes the exponentially advancing technology of the past half-century, specifically illustrated by the number of transistors that can be placed on an integrated circuit board — a quantity that doubles approximately every two years. Personal computing, in its various forms, has become the ubiquitous representation of digital technology’s penetration into every facet of our existence.
Some believe that Moore’s Law is finally approaching its limit, but the law is evident in the capacity of our digital electronic devices, from laptop processing speed to the number of pixels in digital cameras.
1950s — Ferrous-oxide-coated magnetic tape (0.5 in. wide by 1,200/2,400 ft. long) becomes the de facto standard for computers. In the 1980s, thinner Mylar film would allow for 3,600-ft. long tapes.
IBM’s tape drive vacuum column paved the way for magnetic tape to become a popular storage medium. Prior to the vacuum column, fragile magnetic tape was plagued by breakages as it was subjected to sudden starts and stops. IBM devised a solution where the tape was held down by a vacuum during these rapid accelerations and decelerations. Its use in the IBM 701 signaled the beginning of the era of magnetic storage, for its buffering technique would become widely adopted throughout the industry. (IBM)
