Activity #19: Research Definition

1. Data: Refers to individual facts, statistics, or pieces of information. In the context of computer science, data can be anything that is processed or stored by a computer, including text, numbers, images, and more.

2. Structure: The organization or arrangement of components in a system. In programming and data management, "structure" usually refers to how data is organized, stored, and accessed.

3. Data Structure: A specialized format for organizing and storing data so that it can be accessed and modified efficiently. Common types of data structures include arrays, linked lists, stacks, queues, trees, and graphs. Each type of structure offers specific advantages and disadvantages, depending on the operation (insertion, deletion, search, traversal, etc.) needed.

Notations

• [ ] - Square Brackets: Square brackets are often used to represent arrays or lists. In some programming languages, they denote indexing operations (e.g., accessing elements in an array or list). For example:

  • arr[0] refers to the first element in an array.

  • [1, 2, 3] represents a list of numbers.

• { } - Curly Braces: Curly braces are commonly used to denote blocks of code or sets in various programming languages. In Python, for example, they are used to define dictionaries (key-value pairs), while in C-like languages (C, Java, etc.), they are used to group statements, like in functions or control structures.

  • { "key": "value" } represents a dictionary in Python.

  • {1, 2, 3} represents a set.
