HTTP vs HTTPS: The Real Difference between HTTP and HTTPS
Introduction With the ever-growing dependence on the Web, the importance of protecting web services has increased dramatically. If you browse the internet, you have likely come across URLs for web pages that are formatted with either “http://” or “https://” (and if you use the Chrome web browser, you may have also encountered the “Not Secure” […]
Is DevNet Worth it in 2026?
Since Cisco upgraded its certifications in February 2020 and launched the DevNet certification track, one of the most asked questions in the networking domain has been, “Is DevNet worth it?”. So, today in this article, we will look at the answer to this most frequently asked question. If we take a deep dive into DevNet, […]
What is Client-Server Architecture? | Real World Examples
Introduction Client-server architecture is the backbone of most software people use every day. Websites, mobile apps, payment systems, streaming platforms, and enterprise tools often follow this model. The idea is simple. One side asks for something. The other side processes the request and sends a response. Even though the concept is simple, real systems add […]
Peer to Peer Architecture: Concepts, Components, & Examples
Introduction Most people learn networking through a simple picture: one big server, many small clients. That picture is useful, but it is not the whole story. Some systems work better when every device can both ask for data and share data. That is the basic idea behind peer-to-peer (P2P) networking. In a P2P setup, your […]

Network Architecture: Components, Types, & Best Practices
Introduction Every call, video conference, and file we share depends on one factor, i.e., the network’s design. This design is referred to as network architecture. It’s the strategy to determine how devices are connected to each other, how traffic flows, and how services such as DNS, DHCP, and security rules help the business. When the […]
Congestion Control in Computer Networks: A Simple Guide
Introduction Have you ever tried to join a video call, and the audio starts breaking, the screen freezes, and messages take forever to send? In many cases, the internet link is not “down”, it’s just overloaded for a short time. That overload is called congestion. Congestion control in computer networks is the set of ideas […]

Introduction If you keep searching for “which field is best for future?” you are not alone. Students, freshers, working professionals, almost everyone asks this at some point. And honestly, it’s a smart question, because the world is changing fast. Nowadays, AI tools can write code, design posters, summarize reports, and even help doctors read scans. […]
Routing Algorithms in Computer Networks
Introduction Routing algorithms in computer networks decide which paths data packets take to travel from one device to another. Every email, video call, or website request depends on this process. When data leaves a system, it does not travel in one straight line. It moves through many routers. Each router must decide where to send […]
Error Detection and Correction in Computer Networks
Introduction When transmitting data through a network, you are dependent on the end-to-end communication path between two devices. This route is not totally reliable, i.e., information can easily be lost during transmission, packets are lost, and frames can be duplicated. Therefore, error detection and correction in computer networks provide the mechanisms needed to identify transmission […]
