Study Notes
Arrays and Logic Gates
- Arrays are data structures that hold similar, related data.
- Elements are the individual data items within an array.
- Elements have the same data type.
- Indexes are numerical values that represent the position of an element in an array.
- An example of arrays is a list of transportation methods.
- Arrays are useful for storing and accessing collections of data.
Truth Tables
- Truth tables visualize Boolean expression results.
- They show output values for different input combinations.
- Examples are two input variables A and B shown in a table.
Logic Gates
- Logic gates perform Boolean operations.
- Logic gates use binary inputs (0 or 1) and produce a single binary output.
- Basic types of logic gates are illustrated (AND, OR, NOT, NAND, NOR, XOR, XNOR).
Specific Logic Gates: AND
- AND gate outputs "1" only when both inputs are "1."
- Formula: X = A ∧ B (A and B)
- Visual representation includes a symbolic diagram and truth table.
Specific Logic Gates: OR
- OR gate outputs "1" if at least one input is "1."
- Formula: X = A + B (A or B)
- Visual representation includes a symbolic diagram and truth table.
Specific Logic Gates: NOT
- NOT gate inverts the input.
- Formula: X = Ā (NOT A) or Inverter
- Visual representation includes a symbolic diagram and truth table.
Array Operations - Adding/Subtracting
- When adding or subtracting numbers in an array, the numbers are referenced by index.
- Example: Index 3 (value 35) + Index 5 (value 49) = 84.
