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…

Understanding Serialization in Java: A Beginner’s Guide

Understanding Serialization in Java: A Beginner’s Guide

Comments 145 Comments

Serialization is an important concept in Java, especially when you need to save the state of objects or transfer them over a network. In this tutorial, we’ll discuss how serialization and deserialization work in Java using a simple Car class. The process of serialization allows you to save the state of an object to a file, while deserialization allows you to read that object back into memory. Here, we will explore the steps of serializing and deserializing an Car object….

Outcome-Based Education (OBE): A Framework for Quality Education

Outcome-Based Education (OBE): A Framework for Quality Education

Comments 152 Comments

Outcome-Based Education (OBE) is a student-centred teaching and learning approach that focuses on achieving specific, measurable outcomes. These outcomes are defined in terms of the knowledge, skills, and attitudes students are expected to demonstrate after completing a program or course. Unlike traditional education, which emphasizes content delivery and rote memorization, OBE places the learner’s achievements at the center of the educational process. For example, in a Software Engineering program, an outcome might state:“Demonstrate comprehensive knowledge and effective application of software…

Flow Control in Computer Networks

Flow Control in Computer Networks

Comments 1 Comment

Flow control in computer networks ensures efficient communication by managing the data transmission rate between the sender and receiver. The primary objective of flow control is to prevent the sender from overwhelming the receiver with more data than it can process, thereby avoiding buffer overflow and ensuring smooth communication. This tutorial explores flow control in detail, covering its significance, common challenges, and the techniques employed to address them. You can visit the detailed tutorial here. What is Flow Control? Flow…
