Overview:

Data is stored differently depending on its type. Numbers are stored as integers or real numbers, text as string or characters. Lists of the same type of data can be stored in an array.

This webpage examines integer data, real or float data, characters, strings, boolean values, and arrays.

Content Standard(s):
 Digital Literacy and Computer Science DLIT (2018) Grade: 6 21) Identify varying data structures/systems and methods of classification, including decimal and binary. Examples: Difference between a bit and a byte, bit representation, pixels. Unpacked Content Evidence Of Student Attainment:Students will: recognize various data structures and methods of classification such as binary and decimal.Teacher Vocabulary:data structures decimal binaryKnowledge:Students know: how to recognize a binary number system including bits and bytes.Skills:Students are able to: identify how binary can be used for bit representation in pixels.Understanding:Students understand that: there are several data structures and methods for classification. Digital Literacy and Computer Science DLIT (2018) Grade: 7 22) Compare data storage structures. Examples: Stack, array, queue, table, database. Unpacked Content Evidence Of Student Attainment:Students will: explain the differences in a minimum of 3 different data storage structures.Teacher Vocabulary:stack array queue table databaseKnowledge:Students know: different data structures store information in different ways based on the purpose for storage and recall.Skills:Students are able to: compare the best storage structure for storing and recalling data for various purposes.Understanding:Students understand that: each storage structure serves a different purpose depending on what kind of data and the intended use of the data. Digital Literacy and Computer Science DLIT (2018) Grade: 8 21) Differentiate types of data storage and apply most efficient structure. Examples: Stack, array, queue, table, database. Unpacked Content Evidence Of Student Attainment:Students will: identify which data storage structure is used given a set of data and the intent on using that data.Knowledge:Students know: different types of data storage and the appropriate use of those structures.Skills:Students are able to: apply the most efficient data storage given a set of data.Understanding:Students understand that: applying appropriate tools, in this case a data structure, to appropriate task increases efficiency.
