She is today appreciated as the "first programmer" since she was writing programs—that is, manipulating symbols according to rules—for a machine that Babbage had not yet built. She also foresaw the capability of computers to go beyond mere calculating or number-crunching while others, including Babbage himself, focused only on these capabilities.

:What kind of wafers are used at Intel to make computer chips?
:Silicon wafers 12" in diameter, although some plants may still use smaller (8") wafers for some ICs.
They come in ingots, which are solid cylinders 12" in diameter and a few feet long of the purest crytaline silicon 99.999999999% pure, from a company in Japan. Intel uses a special diamond saw blade to cut up the long "log" of silicon into thin wafers (about 2-4 millimeters thick).

:How many nibbles are in a bit?
:A nibble, of (ceramic) silicon, is a {penny;} a half-byte, a nibble, four bits.
There are eight bits in a byte or two nibbles in a byte meaning there are four bits in a nibble.

:The ARPANET 's development began in 1966. It was an experiment to connect universities so they could
share information. What do we call this today?
