Tech+ Lesson

String (text) and character data for Tech+

Last updated: 6/10/2026

Short answer

String (text) and character data. Data types define what kind of data a variable can hold: - Integer: Whole number (no fractional part). Can be positive, negative, or zero. Examples: -3, 0, 42. Use for counting, indexing. - Floating-Point (Float/Double): Number with fractional part (decimal point). Examples: 3.14, -0.001. Stored approximately with limited precision. Use for measurements, calculations. - Boolean: Logical value with only two possible values: true or false. Often result of comparisons. Used for conditions and flags. - Character: Single text character like 'A', 'x', '7'.

Why it appears on the exam

This lesson supports FC0-U71 4.0 on CompTIA Tech+ FC0-U71. The public page gives the basic concept for free; the app adds tracking, quizzes, and weak-area practice.
