Operating System Fundamentals and Interview Questions
Operating System Basic Definitions
Q1. Define Operating System.
Answer: An Operating System (OS) is system software that acts as an interface between the user and computer hardware and manages system resources efficiently.
Q2. What is a Process?
Answer: A process is a program in execution. It consists of program code, data, stack, and resources allocated by the operating system.
Q3. Define PCB.
Answer: PCB (Process Control Block) is a data structure used by the OS to store information about a process,

1. Introduction to the Browser Object Model (BOM)
The Browser Object Model (BOM) allows JavaScript to interact with the browser outside the context of the page’s actual content. While the DOM deals with the document (HTML, CSS), the BOM manages everything else—tabs, windows, history, the address bar, and device information.
At the top of this model sits the window object. Every other object—like navigator, history, location, and the document (DOM) itself—is a property of the window object.

Introduction to JavaScript Objects
In JavaScript, an object is a self-contained environment that stores data as a collection of properties and methods. A property is an association between a name (or key) and a value, while a method is a function associated with an object.
Think of an object as a real-world entity. For example, a Car is an object. It has properties like color, brand, and weight, and methods like start, drive, and brake.
// A simple conceptual look at an object
let car = {

.NET Framework and C# Programming Fundamentals
Unit I: Framework of .NET
1. Building Blocks of the .NET Platform
The .NET platform is built on important components that provide support for application development and execution. The Common Language Runtime (CLR) is the execution environment of .NET that manages memory, security, exception handling, and program execution. The Common Type System (CTS) defines rules for declaring and using data types so that different .NET languages can interact smoothly. The Common Language Specification (CLS) provides

C++ OOP Fundamentals: Classes, Objects, and Encapsulation
C++ was originally called “C with Classes” because its primary purpose was to add Object-Oriented Programming (OOP) features to the C language. Here is a detailed breakdown of these core object-oriented features.
1. Core OOP Concepts
Classes and Objects
- Class: A user-defined data type that acts as a blueprint or template for creating objects. It defines data (attributes) and functions (behavior) grouped together.
- Object: An instance of a class. When a class is defined, no memory is allocated, but memory
