COMPUTER FUNDAMENTALS

Detailed explanation-1: -With data abstraction, users can focus on the machine’s basic functions, which enable them to use the machine as they wish. Take a television remote, for example. The buttons tell you how to increase or decrease the volume and power the television on and off, and these commands are relevant to you.

Detailed explanation-2: -An example of a database abstraction layer on the language level would be ODBC that is a platform-independent implementation of a database abstraction layer. The user installs specific driver software, through which ODBC can communicate with a database or set of databases.

Detailed explanation-3: -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.

Detailed explanation-4: -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.
