analog data

data represented in a continuous and variable form

American Standard Code for Information Interchange (ASCII)

a standard for encoding system for text characters that uses numeric values to represent letters, numbers and symbols

bandwidth

the maximum rate of data transfer across a network or communication channel, usually measured in bits per second

binary

Boolean expression

a logical statement that can only be true or false and uses operators like AND, OR, and NOT

character

a single letter, digit, or symbol used in writing text

character set

a collection of characters that a computer can recognize and process, like ASCII or Unicode compression ratio: the ratio of the original data size to the compressed data size, indication how much the data has been reduced

control structure

constructs in programming that control the flow or execution, such as loops and conditional statements

data

raw facts and figures that can be processed to produce meaningful information

data compression

the process of reducing the size of data to save space or transmission time

data types

categories of data that define what kind or value can be stored, like integers, floats, and strings, and how it can be used

declaration

a statement in programming that specifies the name and type of a variable or function without assigning a value

digital data

data represented using discrete binary values (zeros and ones)
