2.4 Computational Logic

2.4 Computational Logic

1. Logic Gates

   • AND
     • Both Inputs need to be 1 in order for the output to be 1
   • OR
     • When at least 1 of the inputs is 1, the output is 1
   • NOT
     • This does the inverse

2. Binary is a universal computing language

3. For making the table of truths, you need 2^

4. It only consists of 0's and 1's

5. Binary is used because it is easy

6. Hexidecimal

7. 2^1,2^2,2^3,2^4,2^5,2^6,2^7,2^8 = 255

8. Therefore it can be understood by every computer ever.

9. Used for colours

10. Binary Stores less data

11. Booleans

12. However it can overflow
