Hypervisors in Cloud Computing

Hypervisors in Cloud Computing

Comments 0 Comment

A hypervisor, also known as a virtual machine monitor (VMM), is a critical software layer in virtualization technology. It allows multiple virtual machines (VMs) to run on a single physical hardware system by managing and allocating resources such as CPU, memory, and storage to each VM. Hypervisors ensure that each VM operates independently, with isolated environments, while sharing the underlying hardware. Imagine you have a single powerful computer, and you want to run multiple operating systems like Windows, Linux, and…

Cloud Computing Architectures and Deployment Models

Cloud Computing Architectures and Deployment Models

Comments 0 Comment

Cloud Computing Architectures Cloud computing architecture refers to the various components and technologies that work together to deliver cloud-based services. These architectures define how computing resources are organized, managed, and delivered over the Internet. The main components of cloud architecture include front-end and back-end platforms, cloud-based delivery models, and networking infrastructure. You can visit the detailed course on cloud computing here. Visit the detailed tutorial here. Front-End Architecture This is the client-side interface that allows users to interact with cloud…

Virtualization in Cloud Computing

Virtualization in Cloud Computing

Comments 0 Comment

Imagine you have a powerful personal computer at home. You are a single person, and you can utilize it up to a maximum of 30%, while the remaining 70% of the resources are wasted. How can you make full use of your computer’s potential? Introduction to Virtualization Virtualization is a technology that allows multiple virtual environments to run on a single physical hardware system. It works by abstracting hardware resources such as CPU, memory, and storage, creating virtual versions of…

Introduction to Cloud Computing

Introduction to Cloud Computing

Comments 2 Comments

Cloud computing is a technology paradigm that enables users to access computing resources—such as servers, storage, databases, networking, software, and more, over the internet instead of maintaining physical hardware. These resources are on-demand, scalable, and cost-effective, making cloud computing a vital component of modern IT infrastructure. The full tutorial can be accessed here. Key Characteristics of Cloud Computing On-Demand Self-Service Cloud computing allows users to provision computing resources automatically without requiring human intervention. This feature enables users to scale resources…

Operator Overloading in C++

Operator Overloading in C++

Comments 148 Comments

Operator Overloading: In C++, operator overloading allows you to define custom behavior for operators (such as +, -, *, ==, etc.) when they are applied to user-defined types (i.e., objects of classes). This feature enables the creation of expressive and intuitive code, as it allows operators to work with objects in a way that mimics their behavior with built-in types. Operator overloading is a powerful mechanism that enhances the expressiveness of object-oriented code by enabling objects to interact using operators…

Understanding Exception Handling in C++

Understanding Exception Handling in C++

Comments 85 Comments

Introduction to Exception Handling Exception handling is a mechanism in C++ that helps developers handle runtime errors gracefully. Instead of abruptly terminating the program when an error occurs, exception handling allows you to catch and handle errors, ensuring the program continues to run smoothly. In this tutorial, we will learn how to use exception handling in C++ using a simple program. The provided program demonstrates how to handle the case of division by zero, which is a common runtime error….

Composition and Aggregation in C++

Composition and Aggregation in C++

Comments 116 Comments

In Object-Oriented Programming (OOP), Composition and Aggregation describe relationships between classes, specifically how objects are associated with one another. Both are forms of the “has-a” relationship, but they differ in strength and dependency. So in this article we will see the concept of Composition and Aggregation in C++ and also check the difference between Composition and Aggregation. What is Composition? Composition represents a strong relationship between two classes. It is used when an object (child) is a part of another…

Difference between Method/Function Overloading and Overriding (Polymorphism) in C++

Difference between Method/Function Overloading and Overriding (Polymorphism) in C++

Comments 1 Comment

Polymorphism is one of the most powerful and essential concepts of Object-Oriented Programming (OOP). It refers to the ability of a single function, method, or object to behave in different ways depending on the context in which it is used. The term “Polymorphism” is derived from the Greek words poly (many) and morphe (forms), meaning “many forms.” Polymorphism allows you to write flexible, reusable, and maintainable code by enabling a single function or method to process different types of objects….

Understanding Constructors in C++

Understanding Constructors in C++

Comments 120 Comments

Introduction to Constructors: Constructors are special member functions in C++ used to initialize objects. They are automatically invoked when an object of a class is created. The main purpose of a constructor is to set up the initial state of an object by initializing its data members. Types of Constructors: Usage Example: int main(){Car c1(“Black”, “New”, “Mercedes Benz”);c1.start();c1.stop();c1.accelerate();return 0;} Explanation of Code: Usage Example: int main(){ Car c1; c1.start(); c1.stop(); c1.accelerate(); return 0;} Explanation of Code: Common Mistakes to Avoid:…
