Others classify it in terms of the well-established Schumpeterian long waves or Kondratiev waves. On a per capita basis, this is matched by current digital storage (5x10^21 bytes per 7.2x10^9 people). Estimates suggest that the storage capacity of an individual human brain is about 10^12 bytes. While this number is impressive, even in 2007 humanity's general-purpose computers were capable of performing well over 10^18 instructions per second. The number of synaptic operations per second in a human brain has been estimated to lie between 10^15 and 10^17. In terms of capacity, there are two measures of importance: the number of operations a system can perform and the amount of information that can be stored.
has vastly exceeded the cognitive capacity of any single human being and has done so a decade earlier than predicted. An article featured in the journal Trends in Ecology and Evolution in 2016 reported that: The world's technological capacity to compute information with humanly guided general-purpose computers grew from 3.0 × 10 8 MIPS in 1986, to 4.4 × 10 9 MIPS in 1993 to 2.9 × 10 11 MIPS in 2000 to 6.4 × 10 12 MIPS in 2007. Technology was developing so quickly that a computer costing $3000 in 1997 would cost $2000 two years later and $1000 the following year. In the 1990s, the spread of the Internet caused a sudden leap in access to and ability to share information in businesses and homes globally. The world's effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of (optimally compressed) information in 1986 471 petabytes in 1993 2.2 (optimally compressed) exabytes in 2000 and 65 (optimally compressed) exabytes in 2007, the information equivalent of 6 newspapers per person per day. The world's technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986 715 (optimally compressed) exabytes in 1993 1.2 (optimally compressed) zettabytes in 2000 and 1.9 zettabytes in 2007, the information equivalent of 174 newspapers per person per day. As such, Kryder's law prescribes that the amount of storage space available appears to be growing approximately exponentially. The amount of digital data stored appears to be growing approximately exponentially, reminiscent of Moore's law. It is estimated that the world's capacity to store information has reached 5 zettabytes in 2014, the informational equivalent of 4,500 stacks of printed books from the earth to the sun.
This is the informational equivalent to less than one 730- megabyte (MB) CD-ROM per person in 1986 (539 MB per person) roughly four CD-ROM per person in 1993 twelve CD-ROM per person in the year 2000 and almost sixty-one CD-ROM per person in 2007.
The world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes (EB) in 1986 to 15.8 EB in 1993 over 54.5 EB in 2000 and to 295 (optimally compressed) EB in 2007. The World’s Technological Capacity to Store, Communicate, and Compute Information. Connectivity between computers within organizations enabled employees at different levels to access greater amounts of information. īy the early 1980s, along with improvements in computing power, the proliferation of the smaller and less expensive personal computers allowed for immediate access to information and the ability to share and store such for increasing numbers of workers. Accordingly, Moore's law, formulated around 1965, would calculate that the number of transistors in a dense integrated circuit doubles approximately every two years. Rider did not foresee, however, the digital technology that would follow decades later to replace analog microform with digital imaging, storage, and transmission media, whereby vast increases in the rapidity of information growth would be made possible through automated, potentially- lossless digital technologies. He advocated replacing bulky, decaying printed works with miniaturized microform analog photographs, which could be duplicated on-demand for library patrons and other institutions. Library expansion was calculated in 1945 by Fremont Rider to double in capacity every 16 years where sufficient space made available. Overview of early developments Library expansion and Moore's law
