Activity #16: Research Definition

1. Data:
   Data refers to raw facts, figures, or information that can be processed, stored, or analyzed. It can be numbers, text, images, or other types of information that are collected for reference or analysis. For example, sales figures, names, or measurements are all examples of data.

2. Structure:
   Structure refers to the organization or arrangement of something in a particular way, enabling it to serve a specific function. In computing, structure often relates to how data or information is systematically organized and stored.

3. Data Structure:
   A data structure is a specialized format for organizing, processing, and storing data in a computer so that it can be efficiently accessed and modified. Data structures define the relationships among data elements and enable the efficient manipulation of data. Examples include arrays, linked lists, stacks, queues, trees, and hash tables.

Special Characters:

• [ ] (Square Brackets):
  Square brackets are often used in programming for array indexing or to indicate a list of elements. For example, in many programming languages:

  • array[2] refers to the element at the 2nd index of an array.

  • In some contexts, square brackets also denote optional elements in a list or in regular expressions.

• { } (Curly Braces):
  Curly braces are commonly used in programming languages to define blocks of code, such as functions, loops, or conditions.

  Curly braces can also be used to group expressions or elements in various contexts, such as in set notation or JSON objects in web development.
