lossy[ ANS: ]a type of data compression that reduces file size by
permanently eliminating some information, which may affect
quality

real[ ANS: ]a data type representing numbers that can have
fractional parts, often called floating-point numbers
reclocking[ ANS: ]the process of refreshing the timing signals in
digital data to ensure accuracy and synchronization
run-length encoding[ ANS: ]a simple compression technique that
replaces sequences of repeated characters with a single
character and a count
scientific notation[ ANS: ]a method of representing very large or
very small numbers by using powers of 10
signed-magnitude representation[ ANS: ]a way of encoding
positive and negative numbers where one bit represents the sign
and the remaining bits represent the magnitude
string[ ANS: ]a sequence of characters treated as a single data
element and used for text manipulation

strong typing[ ANS: ]a feature in programming languages where
each variable is explicitly declared to be of a specific type,
reducing errors
ten's complement[ ANS: ]a mathematical method for representing
negative numbers in a decimal system
Unicode[ ANS: ]a universal character set that includes characters
from virtually all writing systems, allowing for consistent encoding
and representation of text globally

alphanumeric values[ ANS: ]characters that include both letters
(A-Z) and numbers (0-9)
assignment operator[ ANS: ]a symbol used to assign a value to a

variable, typically =
assignment statement[ ANS: ]a line of code that assigns a value to
a variable, like x = 5
binary operator[ ANS: ]an operator that takes two operands, such
as +, -, *, and /
camel casing[ ANS: ]a naming convention where the first letter is
lowercase and each subsequent word starts with an uppercase
letter, like myVariableName
garbage[ ANS: ]unused or leftover data in memory that the
program no longer needs or references
Hungarian notation[ ANS: ]a naming convention where the name
of a variable starts with a prefix indicating its type, like strName for
a string variable
