IGCSE Computer Science 0478: Logic gates, symbols and functions
Students learn binary and Boolean values, then the standard symbols, single-input and two-input rules, and truth-table outputs of the NOT, AND, OR, NAND, NOR and XOR gates.
One content description from the full IGCSE Computer Science 0478 — 10 Boolean Logic journey. All 16 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
Modules (16)
1
Bits and the binary digits 0 and 1
2
Boolean data
3
What a logic gate is
4
Labelling inputs and the output: A, B, C and X
5
Truth table layout for two inputs
6
The NOT gate
7
The AND gate
8
The OR gate
9
Truth tables for AND, OR and NOT
10
Number of inputs on each gate
11
The NAND gate
12
The NOR gate
13
The XOR (EOR) gate
14
OR versus XOR: the row where both inputs are 1
15
Telling similar gate symbols apart
16
Identifying a gate from its truth table output
