can either be on (1) or off (0)
, they are actually tiny electrical components that can hold positive or negative
charge
binary number system - CORRECT ANSWERS - A system with two numeric
values of 0 and 1, which are also referred to as off or on.
ASCII (American Standard Code for Information Interchange) - CORRECT
ANSWERS - a code for representing English characters as numbers, with each
letter assigned a number from 0 to 127
two's complement - CORRECT ANSWERS - A method of representing
negative numbers in the binary system.
floating-point notation - CORRECT ANSWERS - A real number represented
by a sign, some significant digits (the mantissa) and a power of 2 (the
exponent).
Digital Data - CORRECT ANSWERS - data stored in binary
digital devices - CORRECT ANSWERS - device that works with binary data
T/F: The amount of memory needed to store a letter of the alphabet or a small
number is one bit? - CORRECT ANSWERS - False, one byte
