+"""
+A Buffer Gate is a logic gate in boolean algebra which outputs the same value
+as its input. It is used for signal isolation, increasing drive strength, or
+introducing propagation delay in digital circuits.
+
+In digital electronics, buffers are essential for:
+- Isolating different circuit sections
+- Increasing current drive capability
+- Preventing signal degradation
+- Creating intentional delays in timing circuits
+
+Following is the truth table of a Buffer Gate:
+    ----------------------
+    | Input  |  Output   |
+    ----------------------
+    |   0    |     0     |
+    |   1    |     1     |
