MODULE 6 TYPES AND SOURCES OF DATA

In this video, you will learn about different types and sources of data that we use in computing. Data is information that we record for a purpose, such as counting, measuring, or communicating. Data can be either analog or digital1. Analog data is continuous and can vary in value, such as sound waves or temperature. Digital data is discrete and can only have specific values, such as numbers or letters. You will also learn about some common data types that we use to store and manipulate digital data2. For example, string data type holds characters that can be used to make words and sentences. Integer data type holds whole numbers that can be used for calculations. Boolean data type holds true or false values that can be used for logic. Finally, you will learn about some sources of data that we can use to collect information for our projects3. For example, we can use surveys to ask people questions and record their answers. We can use sensors to measure physical quantities like light or temperature. We can use databases to store and retrieve large amounts of structured data. By the end of this video, you will have a better understanding of what data is, how it is represented, and where it comes from. You will also be able to apply your knowledge to create your own projects using different types of data.
