2. Boolean Logic and logic chips

So what does this have to do with computers?

If you remember from earlier sections, computers perform all calculations using binary arithmetic. Binary uses only two symbols (1 and 0). This maps very well to Boolean logic, which similarly only uses two values (True and False).

The common practice when combining Boolean logic with binary arithmetic is to consider 1s as 'True' and 0s as 'False'.

 

Boolean operations

Boolean logic has only a few simple operations. These operations are:

 

NOT, AND, OR, EXCLUSIVE OR.

But these operations can be combined to create incredibly complicated programs. You can emulate the operations using hardware - logic gates and transistors.

We will now discuss how these operations work, and how they are used.
