Key Differences
Abstraction involves simplifying complex systems by hiding unnecessary details, making it easier to focus on relevant aspects. This technique is prevalent in software engineering, where it helps in managing complexity by emphasizing what a system does rather than how it does it. For instance, in object-oriented programming, abstraction allows programmers to create classes that represent general characteristics of objects, without getting bogged down by the specifics of each object. On the other hand, generalization is about finding commonalities among entities and defining a broader category that encompasses these entities. It's a fundamental concept in various disciplines, including logic, where it refers to the process of formulating general concepts by abstracting common properties of instances. In software development, generalization enables the creation of a general class from which more specific classes can inherit properties, thus promoting code reuse and scalability.
While abstraction aims at reducing complexity by hiding details, generalization seeks to unify similar entities under a broader concept. Both play crucial roles in problem-solving and design by facilitating a more manageable and systematic approach to understanding and organizing information. For example, abstraction allows a software developer to use a complex library by interacting with a simple interface, while generalization lets them create a versatile codebase that can be extended to various specific cases.
Abstraction is often used in conjunction with encapsulation in programming to restrict access to certain parts of an object and only expose what is necessary. This contrasts with generalization, which is more about the relationships between classes, such as inheritance in object-oriented programming, where a general class shares its structure and behavior with more specialized classes.
While both abstraction and generalization are used to reduce complexity and enhance manageability in various domains, they do so through different mechanisms. Abstraction simplifies by hiding details, and generalization expands applicability by identifying and categorizing commonalities. Understanding the distinctions and applications of each can significantly aid in effective problem-solving and system design.

Abstraction
Abstraction in its main sense is a conceptual process where general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods. "An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts, and connects any related concepts as a group, field, or category.Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only the aspects which are relevant for a particular subjectively valued purpose.
Generalization
A generalization is a form of abstraction whereby common properties of specific instances are formulated as general concepts or claims. Generalizations posit the existence of a domain or set of elements, as well as one or more common characteristics shared by those elements (thus creating a conceptual model).
