A **Karnaugh Map** (K-map) is a graphical tool used in Boolean algebra and digital logic design to simplify Boolean functions. It helps in minimizing logical expressions without having to use algebraic methods like Boolean identities. The goal is to create the simplest possible Boolean expression, often leading to a simpler circuit design in digital electronics.

### Key Features:
1. **Grid Representation**: A K-map represents truth tables of Boolean functions in a grid format, where each cell corresponds to a particular combination of input variables.
2. **Grouping**: Adjacent cells (with binary values that differ by only one bit) are grouped together to simplify the expression.
3. **Simplification**: It helps in eliminating redundant variables by forming groups of 1s (or 0s for a "don’t care" condition) to create a minimal Boolean expression.
4. **Visual Aid**: It provides a visual way to see which terms can be combined, making it easier to identify common patterns.

### Steps for Using a K-map:
1. **Construct the Map**: Create a grid based on the number of variables (2-variable, 3-variable, 4-variable K-maps, etc.).
2. **Fill the Map**: Assign the values from the truth table or Boolean function into the map.
3. **Group Adjacent 1s**: Identify and group adjacent 1s to simplify the function (you can group 1, 2, 4, 8 cells, etc.).
4. **Write the Simplified Expression**: From the grouped cells, derive the simplified Boolean expression.

### Example:
For a 2-variable K-map (A and B):
- The K-map would have 4 cells, representing all possible combinations of A and B (00, 01, 10, 11).
- You then fill in the cells based on the given function and group the 1s to simplify the Boolean equation.

4. Can you use Karnaugh Maps for simplifying larger Boolean functions with 5 or more variables?
5. What are the limitations of Karnaugh Maps in digital logic design?

### Tip:
For larger Boolean expressions (more than 5 variables), Karnaugh Maps can become unwieldy, and it may be better to use other methods like the **Quine-McCluskey algorithm** or software tools.
