Data Tables Flashcards
(18 cards)
AND (∧) definition
a logical operator which returns TRUE (or 1) if and only if all inputs are TRUE (or 1)
ASCII definition
a character set used to represent alphanumeric characters or symbols as a set of 8 bits
binary definition
a number system that only uses ones and zeros to represent numbers (a base 2 system)
bitwise manipulation definition
operations performed on a set of bits
boolean definition
a data type that can only store one of two possible values (1 or 0, TRUE or FALSE etc.)
character definition
a data type for storing a letter, number or special character
denary definition
a number system that only uses 10 characters (0 to 9) to represent numbers ( a base 10 system)
floating point arithmetic definition
performing arithmetic operations on floating point numbers in binary
hexadecimal definition
a number system that only uses 16 characters (0 to 9 and A to F) to represent numbers ( a base 16 system)
integer definition
a data type for storing whole number values (positive or negative) with no decimal parts
OR (v) definition
a logical operator which returns TRUE (or 1) if and only if any one of the inputs are TRUE (or 1)
primitive data type definition
a basic built-in data type provided by a programming language
real/floating point definition
a data type for storing numbers with decimal or fractional parts
shifts definition
a bitwise manipulation where a set of bits are all moved by one place in a given direction, and the end bit may be taken as a carry or appended to the other end depending on the shift method
string definition
a data type for storing a sequence of alphanumeric characters or symbols, typically within quotation marks
two’s complement definition
a method of storing negative numbers in binary
it involves flipping all the bits of the binary representation of the positive number and then adding one
UNICODE definition
a character set that is a superset of ASCII
it is used to represent alphanumeric characters or symbols as an integer code point which is equal to that character’s ASCII code
XOR definition
a logical operator which returns TRUE (or 1) if and only if exactly 1 of the inputs are TRUE (or 1)
