Advantages and Disadvantages of Hybrid Topology
Hybrid topology is a network arrangement that combines two or more different basic topologies (such as star, bus, ring, or mesh) to create a customized network structure. This approach allows organizations to leverage the strengths of different topologies while mitigating their individual weaknesses. Unlike pure topologies that follow a single connection pattern, hybrid topology provides flexibility by integrating multiple topological structures within the same network. For example, a company might use star topology for office workstations while connecting different departments through a bus backbone network. Hybrid Topology Example ...
Read MoreDifference Between CCNA and CCNP
Cisco Systems, an internationally recognized provider of networking and IT infrastructure solutions, offers both the CCNA and CCNP certifications. These industry-recognized certificates verify a person's knowledge and skill in Cisco networking technologies. While both certifications focus on networking, they target different skill levels and cover different topics. Read this article to find out more about CCNA and CCNP and how they are different from each other. What is CCNA? CCNA (Cisco Certified Network Associate) is Cisco's entry-level networking certification designed for individuals with basic networking knowledge who want to establish a career in networking. The CCNA certification ...
Read More6 Best Books to Learn Computer Networking
Computer networking is a critical aspect of modern technology. In today's connected world, almost every organization relies on networking to share data and resources. Networking involves connection of multiple devices, such as computers, servers, printers, and other hardware devices, to facilitate communication and data transfer.

Read MoreExplicitly assigning port number to client in Socket
When building client-server applications using sockets, it's essential to assign a unique port number to each client to ensure proper communication between server and clients. By explicitly assigning a port number to each client, the server can identify and communicate with individual clients without confusion or overlap. In this article, we'll explore the importance of assigning port numbers to clients and how to do so effectively. What is a Port Number? In the context of networking, a port number is a 16-bit unsigned integer that uniquely identifies a specific process to which a network packet is directed. When ...
Read MoreFeatures of Good Message Passing in Distributed System
In a distributed system, message passing is a critical component of communication between processes or nodes. Message passing allows processes to share data, coordinate their activities, and respond to changes in the system. A well-designed message passing system can improve performance, reliability, and scalability of a distributed system. Message Passing in Distributed Systems Node A Node B Message Acknowledgment ...
Read MoreFile Accessing Models in Distributed System
In a distributed system, multiple computers work together to provide a cohesive service to users. One of the most critical components is the ability to access files stored on different computers across the network. Different file accessing models have been developed to manage this complexity and ensure efficient and secure file sharing. File Accessing Models in Distributed Systems Centralized Single Server All Files Distributed Multiple Nodes ...
Read MoreActive Directory PenTesting
In today's digital world, cyber attacks are becoming increasingly sophisticated, and organizations must continuously monitor and improve their security measures. Penetration testing, commonly known as pen testing, is a crucial step in identifying vulnerabilities and weaknesses in an organization's systems, networks, and applications. One critical area that needs to be tested is the organization's Active Directory (AD). Active Directory pen testing helps organizations proactively identify security gaps before malicious actors can exploit them, making it an essential component of comprehensive cybersecurity strategy. What is Active Directory? Active Directory is a directory service developed by Microsoft for managing ...
Read MoreWhat is QUAD9 Technology
Quad9 is a free public DNS resolver that protects users from malware, spyware, botnets, and other security threats. Operated by the Swiss-based non-profit Quad9 Foundation, it provides enhanced security and privacy by blocking access to malicious websites while maintaining GDPR compliance through strict data protection policies. Unlike traditional DNS services that may collect and monetize user data, Quad9 does not store or log users' IP addresses. It blocks malicious domains using real-time threat intelligence from cybersecurity experts and companies, preventing devices from connecting to known dangerous websites. How Quad9 Works Quad9 operates as a recursive DNS resolver, ...
Read MoreWPAN Technologies for IoT/M2M
Internet of Things (IoT) devices connect to real-world entities to send and receive data over the internet. Here "Things" refers to any physical entities like smartwatches, health monitoring devices, home appliances, and traffic systems. These devices analyze information from their surroundings and make decisions with minimal human interaction, transmitting results through connected networks to receiver devices such as laptops, tablets, or smartphones. Machine to Machine (M2M) communication enables two or more devices to share functions and data within the same network. These devices can exchange, analyze, and transmit data without human intervention, operating with or without internet connectivity. M2M ...
Read MoreType-C Port in Computer Network
The Type-C Port (also known as USB-C) is a universal connector standard that combines power delivery and high-speed data transfer capabilities. Unlike previous USB standards, USB-C features a reversible design and can deliver up to 100 watts of power, making it suitable for charging everything from smartphones to laptops. USB-C has emerged as the industry standard, gradually replacing older connectors like USB-A, USB-B, and even specialized ports like Thunderbolt and DisplayPort. Its versatility lies in supporting multiple protocols through a single, compact connector. USB-C Port Evolution ...
