Explanation of Solution

Use of abstract tools in the technology:

  • Abstraction refers to the distinction between the external properties of an entity and the details of the entity’s internal composition.
  • Abstraction that allows us to ignore the internal details of a complex device such as a computer, automobile, or microwave oven and use it as a single, comprehensible unit.
  • Computers, automobiles, and microwave ovens are constructed from components, each of which represents a level of abstraction at which the use of the component is isolated from the details of the component’s internal composition.
  • At each level of abstraction, system is viewed in terms of components, called abstract tools, whose internal composition is ignored.
  • Development of large software systems is accomplished in a modular fashion in which each module is used as an abstract tool in larger modules.
  • Subjects such as electrical engineering use MATLAB software to draw graphs, conclusions and simulate circuits without the need to work on paper...
