Data Types Flashcards
Array
Data structure used to store one or more rows of values that share the same data type
ASCII
Simple character set that can represent 128 different characters
Binary
Number system in base 2 that computers use to represent data and instructions
Boolean
Data type that can only store one of two values
Character
Data type that stores a single symbol
Data Type
Property of a particular piece of data that specifies how the data should be treated
Denary
Number system in base 10
Floating Point
Data type that stores a decimal number
Hash Table
Data structure that maps values to keys, where the key for a value is generated by applying an algorithm to that value
Hexadecimal
Number system in base 16 where each digit represents four binary digits
Integer
Data type that stores a whole number
Linked List
List that uses pointers to refer to the location of other elements of the list, allowing it to be reordered without creating a new list
List
Collection of data elements of the same data type
Queue
Data structure where elements are removed in the order in which they are added
Record
Data structure that permits a combination of different data types
Sign and Magnitude Negative Binary
Signed binary that has a 0 added to the front if the value if positive, or a 1 added to the front if the value is negative
Signed Binary
Binary values that can store both positive and negative values
Stack
Data structure where only the most recently added element can be removed
String
Data type that can store a series of characters
Tuple
An ordered list of elements, used to store the data for each record in a database
Two’s Complement Negative Binary
Signed binary that converts between negative and positive values by flipping all bits and adding 1
Unicode
Industry-standard character set that can represent thousands of different characters
Unsigned Binary
Binary values that can store only positive values
