This change from linear type and airwaves to interactive bits and bytes has caused the balance of power to shift to those who aggregate and distribute digital content online.
For example, in 2010 Facebook claimed that they had the largest Hadoop cluster in the world with 21 PB of storage (a Petabyte is 10 to the 15th power bytes of digital information).
Powered by microprocessors with only 156 bytes of memory, it could walk on six legs.
The Altair 8800 kit came with a front panel, a CPU board with the Intel 8080 microprocessor, 256 bytes of RAM, a 4-slot back-plane and an 8-amp power supply for $439.
Beginning with punch card which stores a few bytes of data, storage systems have reached to multiterabytes of capacities in comparatively less space and power consumption.
The complete index entry uses 96 bits, or 12 bytes, of storage.
(Data storage is measured in bytes. The letter N, for example, takes 1 byte to store. A gigabyte is a billion bytes of information).
It will also be possible to build desktop drives capable of storing 400 billion bytes of data and portable drives capable of storing 200 billion bytes.
At this density, I.B.M.'s highest-capacity drives can store 48 billion bytes of data.
It is 18 quintillion bytes of RAM (that is, 18 billion billion), not 16 quintillion.
