Introduction In today's digital world, privacy and data protection have become increasingly important. With sensitive information being transmitted online every day, ensuring that it stays out of the wrong hands is crucial. Image steganography offers an advanced method for keeping your secrets safe by discreetly hiding them within ordinary images or photographs. This comprehensive guide will provide you with valuable insights into various techniques and types of image steganography to help secure your precious data from prying eyes. For anyone interested in cybersecurity, cryptography, and covert communication methods, this article is a must-read! So let's dive in and unveil the ... Read More

Encrypting an image protects communication by rendering it indecipherable for those who do not get the decryption key. One method of encrypting images is using cellular automata, which are mathematical models that use a grid of cells to simulate complex systems. In this article, we'll look at how cellular automata may be employed for encrypted images and why it's so popular. Cellular Automata Analysis To comprehend how cellular automata are applicable to image encryption, you must first understand what they are and how they work. Understanding Cellular Automata In order to understand how cellular automata can be used for ... Read More

Introduction with Historical Background The Interior Gateway Routing Protocol (IGRP) was developed by Cisco Systems in mid 1980s. It is a distance-vector routing protocol and uses the metric called composite metric to calculate the best route between two communication networks. The main purpose of IGRP is to exchange information about networks available within an autonomous system. It supports up to 255 hops, has unlimited hop count, and can perform load balancing over several paths simultaneously. IGRP also allows for easy scalability from large networks down to small ones or vice versa; this makes it suitable for use in many different ... Read More

Background of IEEE 802.6 (DQDB) IEEE 802.6, or Distributed Queue Dual Bus (DQDB), is a metropolitan area network (MAN) technology for LANs developed by the Institute for Electrical and Electronic Engineers' Committee for Computer Communications Standards. It is designed for use in metropolitan areas with wide geographical coverage, such as cities, campuses, and other places where the users are linked together over distances up to 10 kilometers apart. The fundamental idea behind DQDB is to build numerous virtual buses that can be utilised for two endpoints on a network to communicate in both directions. Each bus has its own unique ... Read More

Communication is defined as the transfer or sharing of data between any two individuals through a medium and the medium can be wired or wireless. In a computer network, the OSI (Open System Interconnection) model has seven layers for the communication networks. The First layer of OSI is the Physical layer that uses the Transmission mode for transferring the raw data to other devices using a physical medium. Transferring modes refer to the process of transferring data from one point to the other point or device over a particular network. The Channel between the two devices can be buses or ... Read More
