AP CS Principles Unit 3 Vocab

bit

short for binary digit--either a 0 or 1

byte

8 bits

number bases

used to represent data, includes binary and decimal

binary (base 2)

uses only combinations of the digits zero and one

decimal (base 10)

uses only combinations of the digits 0-9

modulus operator (mod)

arithmetic operator used to return the remainder of a division operation

overflow error

an error caused by the limitation of the range of values and mathematical operations on those values by representing integers with a fixed number of bits

round-off error

an error caused by the limitation of using a fixed number of bits to represent real numbers which limits the range and mathematical operations on those values

list

an ordered sequence of elements; allows multiple related items to be represented using a single variable

element

an individual element in a list that is assigned a unique index

complete list traversal

all elements in the list are accessed

partial list traversal

only a portion of elements in the list are accessed
