COMPUTER FUNDAMENTALS

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: -Examples: Array, List, Map, Queue, Set, Stack, Table, Tree, and Vector are ADTs.

Detailed explanation-3: -The abstract datatype is special kind of datatype, whose behavior is defined by a set of values and set of operations. The keyword “Abstract” is used as we can use these datatypes, we can perform different operations. But how those operations are working that is totally hidden from the user.

Detailed explanation-4: -Data abstraction involves creating a representation for data that separates the interface from the implementation so a programmer or user only has to understand the interface, the commands to use, and not how the internal structure of the data is represented and/or implemented.
