Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
Example: Function overloading
A 3-bit up/down counter can be designed using flip-flops and logic gates.
Use 3 D flip-flops to store the count value.
Connect the Q output of each flip-flop to the D input of the next flip-flop.
Use logic gates to control the direction of counting (up or down).
