Correct!!
analog data - (ANSWER)data represented in a continuous and variable form
American Standard Code for Information Interchange (ASCII) - (ANSWER)a standard encoding system for
text characters that uses numeric values to represent letters, numbers, and symbols
bandwidth - (ANSWER)the maximum rate of data transfer across a network or communication channel,
usually measured in bits per second
binary - (ANSWER)a numerical system that uses only two digits, zero and one, to represent data in
computing
Boolean expression - (ANSWER)a logical statement that can only be true or false and uses operators like
AND, OR, and NOT
character - (ANSWER)a single letter, digit, or symbol used in writing text
character set - (ANSWER)a collection of characters that a computer can recognize and process, like ASCII
or Unicode
compression ratio - (ANSWER)the ratio of the original data size to the compressed data size, indicating
how much the data has been reduced
control structure - (ANSWER)constructs in programming that control the flow of execution, such as
loops and conditional statements

Correct!!
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

Correct!!
lossless - (ANSWER)a type of data compression where no information is lost and the original data can be
perfectly reconstructed
lossy - (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
radix point - (ANSWER)the decimal point in a number system that indicates the separation between
integer and fractional parts
real - (ANSWER)a data type representing numbers that can have fractional parts, often called floating-
point numbers
reclocking - (ANSWER)the process of refreshing the timing signals in digital data to ensure accuracy and
synchronization
run-length encoding - (ANSWER)a simple compression technique that replaces sequences of repeated
characters with a single character and a count

Correct!!
scientific notation - (ANSWER)a method of representing very large or very small numbers by using
powers of 10
signed-magnitude representation - (ANSWER)a way of encoding positive and negative numbers where
one bit represents the sign and the remaining bits represent the magnitude
string - (ANSWER)a sequence of characters treated as a single data element and used for text
manipulation
strong typing - (ANSWER)a feature in programming languages where each variable is explicitly declared
to be of a specific type, reducing errors
ten's complement - (ANSWER)a mathematical method for representing negative numbers in a decimal
system
Unicode - (ANSWER)a universal character set that includes characters from virtually all writing systems,
allowing for consistent encoding and representation of text globally
alphanumeric values - (ANSWER)characters that include both letters (A-Z) and numbers (0-9)
assignment operator - (ANSWER)a symbol used to assign a value to a variable, typically =
assignment statement - (ANSWER)a line of code that assigns a value to a variable, like x = 5
binary operator - (ANSWER)an operator that takes two operands, such as +, -, *, and /
