2.1 Data and Information

• Match the type of data with its description:

  Structured Data ↔️ Data organized in a fixed format

  Unstructured Data ↔️ Data without a pre-defined format
• Data is unprocessed and unorganized
• Structured data is organized in a fixed format, while unstructured data is not.

  True
• What type of data is a list of sales figures for a product?

  Data
• What is the key difference between data and information?

  Data is raw, information is meaningful
• What are the two main types of data?

  Structured and unstructured
• Information is derived from data through processing and organization


  True
• What is the purpose of information derived from data analysis?

  Enable decision-making
• What is an example of data that can be used to generate information?

  Weather measurements
• The ability to effectively manage, process, and analyze data is a core competency in computer science

  True
• What are the two main categories of data?

  Structured and unstructured
• What is the key difference between data and information?

  Data is raw, information is processed
• The transformation of data into information is crucial for extracting meaningful insights
• Data is unorganized and lacks inherent meaning
• Raw sensor data from a manufacturing process can be analyzed to show production efficiency
• Data refers to raw facts or figures that can be stored and processed to produce information


  True
• The key difference is that structured data has a clear, consistent structure, while unstructured data lacks a predefined format
• Order the steps involved in transforming data into information:

  1️⃣ Collect raw data

  2️⃣ Process and organize data

  3️⃣ Analyze and interpret data

  4️⃣ Derive meaningful insights
• Understanding the difference between data and information helps in effective data management and analysis


  True
• Why are data and information considered fundamental concepts in computer science?

  They drive innovation
• Data refers to facts, figures, symbols, or observations
• Information is derived from data through processing and organization


  True
• What are the characteristics of information compared to data?

  Meaningful and contextualized
• What is the role of processing in transforming data into information?

  Provides meaning and context
• What type of information is a weather forecast predicting rain?

  Information
• In each case, the data represents the raw facts, while the information provides meaningful insights and knowledge
• Match the type of data with its description:

  Structured Data ↔️ Data organized in a fixed format

  Unstructured Data ↔️ Data without a predefined format
• What are the characteristics of information as opposed to data?

  Meaningful, contextualized knowledge
• Data can be either structured, like databases, or unstructured, like text documents
• In each case, data represents the raw facts, while information provides meaningful insights derived from analyzing and contextualizing that data.
• Match the term with its role in computer science:

  Data ↔️ Fundamental building block

  Information ↔️ Enables decision-making
