Q1. What is OOAD? Explain concepts of objects and class with the help of examples and diagrams. Ans. Object-oriented analysis and design (OOAD) is a popular technical approach for analyzing and designing an application, system, or business by applying objectoriented programming, as well as using visual modeling throughout the development life cycles to foster better stakeholder communication and product quality. OOAD in modern software engineering is typically conducted in an iterative and incremental way. The outputs of OOAD activities are analysis models (for OOA) and design models (for OOD) respectively. The intention is for these to be continuously refined and evolved, driven by key factors like risks and business values Object and Class The concepts of objects and classes are intrinsically linked with each other and form the foundation of object–oriented paradigm.

Q1. (a) What is the need of modulating a signal? Will it be a right approach to send the    information as the signal itself?     Ans:   Modulation is the process of mixing a low energy message signal with the high energy carrier signal to produce a new high energy signal which carries information to a long distance. Modulation is the process of changing the characteristics (amplitude, frequency or phase) of the carrier signal, in accordance with the amplitude of the message signal. A device that performs modulation is called modulator.  Need for Modulation Modulation is extremely necessary in communication system because of the following reasons: 1) Avoids mixing of signals 2) Increase the range of communication 3) Wireless communication 4) Reduces the effect of noise 5) Reduces height of antenna Q1.  (b) Explain techniques used in digital to analog modulation with the help of diagram. Ans:  Coming Soon... For rest...

MCS-024 Object Oriented Technologies and Java Programming Solved Assignment 2019-2020 Q1. (a)   Explain basic concepts of Object Oriented Programming? Explain how data hiding is achieved.    Answer:- Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects. It simplifies the software development and maintenance by providing some concepts: ·          Object -  Any entity that has state and behaviour is known as an object. An Object can be defined as an instance of a class. ·          Class -  Collection of objects is called class. It is a logical entity. A class can also be defined as a blueprint from which you can create an individual object. Class doesn't consume any space. ·          Inheritance -  When one object acquires all the properties and behaviours of a parent object, ...
