Question and answer of Software Engineering

-

Q.1-   Explain various component of Software.

Ans-  

  1. System Software:

    • Operating System (OS): The fundamental program that manages computer resources (memory, CPU, storage, etc.) and provides an interface for users to interact with the system. Exampels include linux, macOS and windows.
    • Language processor: converts high-level programming languages(like Java, C++, python) into machine-readable instructions (object code or machine code).
    • Device Driver : Controls externals devices(printers, mice, modems) and enables them to function with the computer system.

  2. Application Software:

    • General Purpose Software; Versatile programs used for various task(eg- web browsers, office suites, media players).
    • Customized Software: Tailored solutions for specific business needs or industries.
    • Utiltiy Software: Tools that enhance system performance, security, or maintanance (eg: antivirus, disk cleanup).
  3. Software Components
  • Modules: Specific functions or sets of functions (e.g., a calculator module).
  • Software Components: Well-defined, modular, reusable functionalities that interact with other components. they integrate specific functions or groups of function.
  • Individual Software Components: These encapsulate related functions or data and communicate with each other via interfaces. Each component provide a 'Provide interface' for other components to use.

Raster scan Vs Vector Scan

1. Raster Scan Display   How It Works : A raster scan display works by painting an image on the screen pixel by pixel, row by row. It follows a systematic pattern where the electron beam (in CRT monitors) or the display elements (in modern LCD/LED screens) sweep across the screen from left to right, top to bottom, in a series of horizontal lines (scan lines). This process is akin to how a traditional TV screen works.   Process : The display draws the image starting from the top-left corner, moving to the right, then moves to the next row below, and repeats this process until the entire screen is filled. This pattern creates a grid of pixels, where each pixel can have a color and brightness level.   Characteristics : Pixel-based : The screen consists of a grid of pixels, and each pixel can have a distinct color and intensity. Continuous Image : Raster scan displays are capable of displaying detailed and complex images, including photographs and videos, because they break t...

Inheritance

*■ Inheritance*  • Inheritance is a concept in OOP that allows a class to inherit properties and behaviors (methods) from another class. • A class that inherits from another class is called a derived class (or subclass) • The class which gets inherited by another class is called the base class (or superclass). • Inheritance is possible only if there is is-a relationship between parent and child class. • constructors are not inherited in derived class, however the derived class can call default constructor implicitly and if there's a parameterised constructors in bass class then derived class can call it using 'base' keyword.  ____________________________________________  *➤ Rules of Inheritance*  1) C# supports single inheritance, meaning a class can inherit from only one base class. 2) A parent class constructor must be accessible in child class otherwise  inheritance will be not possible. 3) every class, whether user-defined or predefined implicitly derives fr...

unit -1 Introduction of Image processing

-
  What is Image Processing? Image processing is a method to perform operations on an image to enhance it or extract useful information. It is a type of signal processing where the input is an image, and the output may be either an image or characteristics/features associated with that image. Goals of Image Processing Image Enhancement : Improving visual appearance (e.g., contrast, sharpness) Image Restoration : Removing noise or distortion Image Compression : Reducing the amount of data required to represent an image Feature Extraction : Identifying objects, edges, or patterns Image Analysis : Understanding and interpreting image content Object Recognition : Detecting and identifying objects in an image What is an Image? An image is a two-dimensional function f(x, y) , where x and y are spatial coordinates, and f is the intensity (brightness or color) at that point. For digital images, both x, y, and f are finite and discrete. Types of Image Representation...
