data
answer- raw facts and figures that can be processed to
produce meaningful information
data compression
answer- the process of reducing the size of data to save
space or transmission time
data types
answer- categories of data that define what kind of value
can be stored, like integers, floats, and strings, and how it
can be used
,declaration
answer- a statement in programming that specifies the
name and type of a variable or function without assigning
a value
digital data
answer- data represented using discrete binary values
(zeroes and ones)
floating point
answer- a way to represent real numbers that can have
fractional parts using a format that includes a base and an
exponent
Huffman encoding
Answer- a compression technique that uses variable-
length codes for data representation based on frequency of
occurrence
,information
answer- data that have been processed or organized in a
meaningful way to be useful
integer
answer- a whole number
keyword encoding
answer- a method of data compression that replaces
frequently occurring patterns with shorter codes
lossless
answer- a type of data compression where no information
is lost and the original data can be perfectly reconstructed
, loss
answer- a type of data compression that reduces file size
by permanently eliminating some information, which may
affect quality
numeric
answer- any value that is a number
overflow
answer- a condition in which a calculation exceeds the
maximum value that can be represented within a given
number of bits
pulse-code modulation (PCM)
answer- a method used to digitally represent analog
signals
