Data
- Data is factual information that can be used for reasoning, discussion, or calculation. It can be represented as numbers, characters, images, sounds, or any other form that can be processed by a computer. Data is often organized into structures, such as tables, to provide additional context and meaning.
Structure
- Structure refers to the arrangement and organization of elements in a system or object. It can be applied to both physical and abstract entities. For example, a building has a physical structure, while a language has an abstract structure.
Data Structure
A data structure is a specialized format for organizing, processing, retrieving, and storing data. It defines the relationships between data elements and the operations that can be performed on them.
Data structures are essential for efficient data management in various applications, including databases, operating systems, computer graphics, and artificial intelligence.
[]- Square Bracket
Enclosing parenthetical information: Square brackets are often used within quoted text to indicate that a writer has added material to clarify or explain the original quote.
Mathematical expressions: They can denote a matrix, indicate a closed interval, or represent the least common multiple.
Computer programming: Square brackets are used in programming languages to define arrays, access elements within arrays, or specify character ranges.
-
Set notation: In mathematics, curly braces are used to define a set by enclosing its elements.
Computer programming: Curly braces are used in many programming languages to define blocks of code, such as functions, loops, and conditional statements.
Curly braces are also used in other contexts, such as in music to connect multiple lines of music that should be played simultaneously.
