What has more memory 5 gigabytes or 8 megabytes?
A gigabyte is 1024 megabytes. Five gigabytes is about 600 times as large as 8 megabytes. My first electronic computer had 64 bytes of memory. The first IBM PC used 160 kilobyte diskettes, and had 256 kilobytes of ram. A computer with 5 gigabytes of memory would be have about 2.5 million times as much RAM as that PC, and 10.4 billion times as much memory as my first computer. Steve Wozniak, who built the first Apple computer (Steve Jobs was just a software guy and a salesman), said it would have been an abject failure except that the price of a "2002" memory chip dropped in price precipitously. He asserted a law that "Sooner or later, every computer chip drops in price to $2.50." If you adjust for the larger size of today's chips, and adjust for inflation, his law is still true 37 years later.
