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 is the reduction of a particular body of data to a simplified representation of the whole. Abstraction, in general, is the process of removing characteristics from something to reduce it to a set of essential elements.

Detailed explanation-4: -Another real life example of Abstraction is ATM Machine; All are performing operations on the ATM machine like cash withdrawal, money transfer, retrieve mini-statement…etc. but we can’t know internal details about ATM. Note: Data abstraction can be used to provide security for the data from the unauthorized methods.
