Three LawsMoore’s law:The performance of memory chips doubledevery 18 to 24 months, whereas their size and cost remained roughly constant (Gordon Moore, 1965)
Metcalf ’s law:The usefulness of a network increases with the square of the number of users connected to the network (Robert Metcalfe, 1980)
Kryder’s law:Since the introduction of the disk drive in 1956, the density of information it can record has swelled from a paltry 2,000 bits to 100 billion bits (gigabits), all crowded in the small space of a square inch. That represents a 50-million-fold increase (Mark Kryder, 2005)
