Abstraction
Abstraction is the process of removing unnecessary details from a problem in order to focus on the essential elements. It is a key concept in both computer science and software engineering, but it is used in different ways in each discipline.
In computer science, abstraction is used to create models of real-world systems. These models can be used to study the behavior of the system without having to worry about the details of its implementation. For example, a computer scientist might create an abstract model of a computer network in order to study the flow of data through the network. This model would not need to include all of the details of the network’s hardware and software, but it would need to capture the essential features of the network’s behavior.
In software engineering, abstraction is used to create software components that can be reused in different contexts. For example, a software engineer might create an abstract component that represents a user interface. This component could be used in different software applications, without having to be rewritten each time. This can save time and effort, and it can also help to ensure that the user interface is consistent across different applications.
The different ways that abstraction is used in computer science and software engineering reflect the different goals of the two disciplines. Computer science is focused on understanding the fundamental principles of computing, while software engineering is focused on the practical application of those principles to the design and development of software systems. Abstraction is a powerful tool that can be used to achieve both of these goals.
