Activity #16: Research Definition

1. Data

Definition: Data refers to the information or raw facts that can be processed by a computer system. Data can be in various forms like numbers, characters, images, or even complex objects.

• Examples:

  • Integer: 42

  • String: "Hello, World!"

  • Boolean: true or false

2. Structure

Definition: Structure refers to the arrangement or organization of elements, in this case, data, to enable efficient processing and utilization. In computer science, structure implies a systematic format or pattern that defines how data is stored and accessed.

• Examples:

  • Arrays: A sequence of data elements of the same type, stored in contiguous memory.

  • Linked List: A collection of nodes where each node contains data and a reference to the next node.

3. Data Structure

Definition: A data structure is a specialized format to organize, manage, and store data in a way that enables efficient access and modification. Data structures allow the computer to store data in an organized way, ensuring better performance in terms of time complexity and space usage.

• Examples:

  • Arrays [ ]: Store elements in a fixed-size sequence and allow access via index.

  • Stacks: Follows the Last In, First Out (LIFO) principle.

  • Queues: Follows the First In, First Out (FIFO) principle.

  • Hash Maps { }: Key-value pairs for quick lookups.
