ABSTRACT

From bits to terabytes Some of the terms mentioned in this section have been defined earlier in the book, but these are the fundamental unite of data for microelectronic systems so they are repeated here, from the smallest to the currently largest: • Bit: the unit of information. Takes one of

two binary values, 0 or 1. In logical terms, these may mean TRUE and FALSE. In positive logic, 1 is TRUE and 0 is FALSE, and this is the system most commonly used. In electronic terms, 0 means low voltage (usually very close to 0 V) and 1 means high voltage (usually close to the supply voltage, which is +5 V in TTL systems.).
