Logic in Computer Science

How Logic Powers Technology

Computers rely on symbolic logic at their very core! Logical operations are used in circuits, algorithms, and programming languages.

Logic Gates

Logic gates in hardware use AND, OR, and NOT operations to process information and make decisions.

Programming with Logic

When you write a program, you use logical conditions like if (x > 0) { ... } to control what the computer does.

Real-World Impact

From video games to smartphone apps, logic helps computers follow instructions, make choices, and solve problems.

Examples

  • A security system uses logic to trigger an alarm if a door is open AND the code is wrong.

  • A search engine uses logical operators to find web pages that match your keywords.
