**Adders and flip-flops**

The Arithmetic and Logic Unit (ALU) in a CPU uses a half-adder logic circuit for performing binary addition of two bits. The input consists of two bits, A and B, and hence, 22=4 input combinations are possible

This A Level Computer Science module introduces adders and flip-flops to your students, explaining:

- Half adders
- Full adders
- Sequential circuits
- D flip-flops

**More Data types, data structures and algorithms **

Adders and flip-flops is one lesson in our Data types, data structures and algorithms module. The other theory lessons can be found below:
