Logic & Databases
This hub features interactive quizzes to sharpen your understanding of Boolean logic, digital circuits, and database query languages. Practice interpreting logic gates, completing truth tables, and writing effective SQL queries. Enhance your logical thinking and data management skills.
Logic Gates Basics
Introduces fundamental logic gates (AND, OR, NOT, NAND, NOR, XOR), their symbols, and how they determine output from inputs.
LaunchLogic Gates
Tests understanding of NOT, AND, OR, NAND, NOR, and XOR gate symbols and functions.
LaunchLogic Circuits (2-3 Gates)
Interpret and trace inputs through simple circuits with 2 or 3 combined gates. Understand order of logical operations.
LaunchLogic Circuits (Joined Symbols)
Interpret and trace inputs through joined logic gate diagrams. Match circuit diagrams to their corresponding Boolean expressions.
LaunchAdvanced Logic Circuits
Challenging analysis of complex logic circuits, including True/False and fill-in-the-blank questions.
LaunchLinked Logic Circuit Diagrams
Analyze and trace inputs through diagrams with multiple linked gates. Practice matching circuits to Boolean expressions.
LaunchTruth Table Logic Gate
Complete truth tables for various logic gates (AND, OR, XOR, NAND, NOR, NOT). Includes step-by-step feedback.
LaunchLogic Gate Combinations
Evaluate Boolean expressions step-by-step. Complete truth tables for complex logic gate combinations.
LaunchSQL Queries (Basic)
Practice writing fundamental SQL queries to select data from tables using basic WHERE clauses.
LaunchSQL Queries (Advanced)
Write SQL queries using more advanced clauses like `WHERE`, `LIKE` for pattern matching, and `ORDER BY` for sorting results.
