FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -For example, when using a cell phone, you can figure out how to answer incoming calls and respond to text messages. Thanks to data abstraction, you can’t tell how the phone itself transmits signals. The purpose of data abstraction is to expose only the essential elements of a device.

Detailed explanation-2: -There are four types of abstracts: informative, descriptive, critical, and highlight abstracts. However, students most often use informative abstracts.

Detailed explanation-3: -Data abstraction refers to providing only essential information to the outside world and hiding their background details, i.e., to represent the needed information in program without presenting the details.

Detailed explanation-4: -Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable. For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added.
