1. analog data data represented in a continuous and variable form
2. American Stan- a standard encoding system for text characters that uses numeric values to
dard Code for In- represent letters, numbers, and symbols
formation Inter-
change (ASCII)
3. bandwidth the maximum rate of data transfer across a network or communication channel,
usually measured in bits per second
4. binary a numerical system that uses only two digits, zero and one, to represent data in
computing
5. Boolean expres- a logical statement that can only be true or false and uses operators like AND, OR,
sion and NOT
6. character a single letter, digit, or symbol used in writing text
7. 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, indicating how much the data has been reduced
8. control structure constructs in programming that control the flow of execution, such as loops and
conditional statements
9. data raw facts and figures that can be processed to produce meaningful information
10. data compres- the process of reducing the size of data to save space or transmission time
sion
11. data types categories of data that define what kind of value can be stored, like integers, floats,
and strings, and how it can be used

12. declaration a statement in programming that specifies the name and type of a variable or
function without assigning a value
13. digital data data represented using discrete binary values (zeroes and ones)
14. floating point a way to represent real numbers that can have fractional parts using a format that
includes a base and an exponent
15. Huffman encod- a compression technique that uses variable-length codes for data representation
ing based on frequency of occurrence
16. information data that have been processed or organized in a meaningful way to be useful
17. integer a whole number
18. keyword encod- a method of data compression that replaces frequently occurring patterns with
ing shorter codes
19. lossless a type of data compression where no information is lost and the original data can
be perfectly reconstructed
20. lossy a type of data compression that reduces file size by permanently eliminating some
information, which may affect quality
21. numeric any value that is a number
22. overflow a condition in which a calculation exceeds the maximum value that can be repre-
sented within a given number of bits
23. pulse-code mod- a method used to digitally represent analog signals
ulation (PCM)
24. radix point the decimal point in a number system that indicates the separation between
integer and fractional parts
