Topic 5 Part 3 Flashcards
Define Data Type
A data type defines the kind of value that can be stored in a column or variable in a database or programming language. It specifies the type of data, such as numbers, text, dates, or booleans, and dictates the operations that can be performed on that data. Common data types include:
Integer: Whole numbers (e.g., 1, 42)
String: Text (e.g., “Hello”)
Date: Dates (e.g., “2025-01-28”)
Boolean: True/False values
Float: Decimal numbers (e.g., 3.14)
Define machine learning
Machine learning is a field of artificial intelligence (AI) that involves creating algorithms and models that allow computers to learn from data and make predictions or decisions without being explicitly programmed. It uses statistical methods to find patterns in data, and over time, the model improves its performance as it is exposed to more data. Machine learning is widely used in applications like image recognition, natural language processing, and recommendation systems.
