Understanding Bit
Variation A
Short for binary digit, the smallest unit
of information on a machine. A single bit can
hold only one of two values: 0 or 1. More
meaningful information is obtained by combining
consecutive bits into larger units. For example,
a byte is composed of 8 consecutive bits.
Computers are sometimes classified by the
number of bits they can process at one time
or by the number of bits they use to represent
addresses. These two values are not always the
same, which leads to confusion. For instance,
classifying a computer as a 32-bit machine might
mean that its data registers are 32 bits wide or
that it uses 32 bits to identify each address
in memory. Whereas larger registers make a
computer faster, using more bits for addresses
enables a machine to support larger programs.
Graphics are also often described by the
number of bits used to represent each dot.
A 1-bit image is monochrome; an 8-bit
image supports 256 colors or grayscales;
and a 24- or 32-bit graphic supports true color.
Variation B
Also called binary digit. A single,
basic unit of information, used in connection
with computers and information theory.
Variation C
Either of the digits 0 or 1 when used in the
binary number system.
Variation D
Either of the digits 0 or 1, used in the
binary number system
Variation E
Either 0 or 1 in binary notation
Variation F
Either of the digits 0 or 1, used in the
binary number system.
Variation G
A fundamental unit of information having
just two possible values, as either of the
binary digits 0 or 1.
Variation H
The smallest unit of computer memory.
A bit holds one of two possible values,
either of the binary digits 0 or 1. The
term comes from the phrase binary digit.
Variation I
The smallest unit of information. One
bit corresponds to a “yes” or “no.” Some
examples of a bit of information: whether
a light is on or off, whether a switch
(like a transistor) is on or off, whether
a grain of magnetized iron points up or down.
Variation J
In the binary system, a bit (binary digit)
either of the digits 0 or 1. It is the basic
unit for storing data, with "off" representing 0
and "on" representing 1
