Analog data - ANS data represented in a continuous and variable form
American Standard Code for Information Interchange (ASCII) - ANS a standard encoding
system for text characters that uses numeric values to represent letters, numbers, and symbols
bandwidth - ANS the maximum rate of data transfer across a network or communication
channel, usually measured in bits per second
binary - ANS a numerical system that uses only two digits, zero and one, to represent data in
computing
Boolean expression - ANS a logical statement that can only be true or false and uses
operators like AND, OR, and NOT
character - ANS a single letter, digit, or symbol used in writing text
character set - ANS a collection of characters that a computer can recognize and process, like
ASCII or Unicode

, compression ratio - ANS the ratio of the original data size to the compressed data size,
indicating how much the data has been reduced
control structure - ANS constructs in programming that control the flow of execution, such as
loops and conditional statements
data - ANS raw facts and figures that can be processed to produce meaningful information
data compression - ANS the process of reducing the size of data to save space or transmission
time
data types - ANS categories of data that define what kind of value can be stored, like integers,
floats, and strings, and how it can be used
declaration - ANS a statement in programming that specifies the name and type of a variable
or function without assigning a value
digital data - ANS data represented using discrete binary values (zeroes and ones)
floating point - ANS a way to represent real numbers that can have fractional parts using a
format that includes a base and an exponent
Huffman encoding - ANS a compression technique that uses variable-length codes for data
representation based on frequency of occurrence
information - ANS data that have been processed or organized in a meaningful way to be
useful
