Glossary


















AND Gate:
a logic circuit designed to
compare TRUE-FALSE (or on-off or one-zero) inputs and pass a
resultant TRUE signal only when all the inputs are TRUE.Binary: having two components or possible
states.Binary code: a system
for representing things by combinations of two symbols, such as one
and zero, TRUE and FALSE, or the presence or absence of
voltage.Binary number system: a
number system that uses two as its base and expresses numbers as
strings of zeros and ones.Bit: the
smallest unit of information in a computer, equivalent to a single
zero or one. The word "bit" is a contraction of binary
digit.Boolean algebra: a
method for expressing the logical relationships between entities
such as propositions or on-off computer circuit; invented by the
19th Century English mathematician George Boole.Byte: a sequence of bits, usually eight, treated as a unit for
computation or storage.Carry: the digit added
to the next column in a an additional problem when the sum of the
numbers in a column equals or exceeds the number
base.Kilobyte: 1,024 bytes
(1,024 being one K, or two to the 10th power); often used as a
measure of memory capacity.Logic Gate: a circuit  that accepts one or more than one input and
always produces a single predicatable output.OR gate: a circuit designed to compare binary TRUE-FALSE
(or on-off or one-zero) inputs and pass a resultant TRUE signal if
any input is TRUE.XOR gate: a circuit
designed to compare binary TRUE-FALSE (or on-off or one-zero) inputs
and pass a resultant TRUE signal if a single input is TRUE,
otherwise the output is FALSE.
