My first computer was a device that had 65KB of RAM (random access memory, the working memory of the device), and memory was expensive (this fact dates me). Note the unit is kilobytes – 1000 bytes. The Apollo 11 space craft’s guidanceContinue reading “You have a Science Laboratory in the Palm of Your Hand”
