CP - Data Representation [LESSON]

Data Representation

Introduction

In the world of computer science, data collection is an essential process that influences how we interact with technology every day. Recognizing the storage and representation of data through various tools can help you understand the fundamental concepts behind binary numbers, logic, sets, and functions. These concepts play a crucial role in computer science, shaping the way information is processed, organized, and utilized in the digital world. Like how your data is collected and used on social media. Or even how your favorite video games represent characters uses binary. All of which just provide a snippet of data in the digital world.  As you jump into data in the digital world, you will pave the way for innovative solutions and advancements in technology that rely on a strong foundation of understanding data at its core.

Knowledge Point

Data is a crucial aspect of computer science, and it plays a vital role in various fields. In order to make sense of data, it needs to be collected and stored in a meaningful way. So in this lesson, you will explore the concept of data storage and representation, as well as the tools and processes used for data collection.

  • Data can be stored and represented in different formats, and one important aspect to understand is binary numbers. Computers use a binary system that consists of only two digits, 0 and 1. This system allows computers to represent and store data in a way that can be easily processed by the computer's logic circuits.
  • Another important concept in data storage and representation is logic. Logic provides a set of rules and principles that govern the manipulation and processing of data. Boolean logic, for example, is a type of logic that uses operators such as "not," "or," and "and" to enhance searches and help retrieve specific information from a dataset.
  • In addition to binary numbers and logic, sets, and functions are also relevant to data storage and representation. Sets are collections of unique elements, while functions establish relationships between inputs and outputs. These concepts allow us to organize and categorize data in a meaningful way.

When it comes to data collection, both computational and non-computational tools and processes are used. Computational tools include software and programs that automate data collection, while non-computational tools can be as simple as pen and paper or observational methods.

Conceptual Understanding

Let’s now take a look at some real-world examples of the concepts previously discussed. Look at the learning object below to learn more about how we can see the importance of data.
