Study Notes
Section 1: Spaced Learning
- An algorithm is a set of step-by-step instructions designed to solve a problem.
- Algorithms are commonly used to plan out solutions to problems efficiently.
-
Logic Gates:
- AND Gate: The output is true only if both inputs are true.
- OR Gate: The output is true if at least one input is true.
- NOT Gate: Reverses the input; if the input is true, the output is false, and vice versa.
- Binary is a numeral system that uses a sequence of 1s and 0s to represent data, fundamental to computer communication.
- To create a variable named age and assign the value of 30 in Python, the correct syntax is
age = 30. - In Python, the equality comparison operator to check if two values are equal is
==.
Section 2: Written Practice
-
Flowol Symbols: Common shapes include:
- Oval: Start/End
- Parallelogram: Input/Output
- Rectangle: Process
- Diamond: Decision/Logic
- A Truth Table outlines all possible input combinations for logic gates and their corresponding outputs.
- Binary to Denary Conversion: To convert binary numbers (e.g., 00001111) to denary, each binary digit represents a power of 2, counting from the right (0, 1, 2, etc.). For instance, 00001111 in binary is equal to 15 in denary.
