Abstraction is a concept that simplifies complex systems by focusing on the essential features while ignoring the irrelevant details. For example, when using a car, you don’t need to understand how the engine works or the intricacies of the electrical system. Instead, you just need to know how to drive it, which makes it easier for everyone to use without needing technical knowledge. In computer science, abstraction helps programmers manage complexity by creating models that represent real-world objects. For instance, a class in programming can represent a dog with properties like color and breed, allowing developers to work with these objects without worrying about their internal workings.
