I really love the simple real-life examples given in this book.

In software engineering , a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects , without specifying the final application classes or objects that are involved.

In simple terms, design patterns are nothing but a tried-and-tested solution to common programming problems, for example, the creational design patterns deal with the problems of object creation. This book documented 24 design patterns that are reusable to solve common programming problems. The benefit of design patterns are immortal; you will find them in many frameworks, libraries, and in-built programming languages. You probably use them on a daily basis, even if you don't realize they are there.
