Introduction Data communication involves the exchange of information between two or more devices connected through a communication channel. The effectiveness and efficiency of this exchange process are highly dependent on the protocol used to transmit the data. Synchronous Data Link Control (SDLC) is an essential protocol for data communication as it provides a reliable means of transmitting data across networks. Synchronous Data Link Control is a layer 2 protocol used in data communication to manage and maintain error−free transmission between devices. SDLC provides synchronization, error control, and flow control mechanisms necessary for efficient data transfer. SDLC Loop Operation ... Read More

Introduction In the world of electronics, transmission lines are an essential part of many circuits. One such type of transmission line is the Symmetric Stripline. This article provides a detailed look at this technology, including its definition, construction, working principle, applications, and more. A Symmetric Stripline is a type of electrical transmission line that consists of two parallel conductive strips separated by a dielectric material. It is commonly used in high−frequency and microwave circuits due to its ability to provide low loss and good impedance matching properties. Construction of Symmetric Stripline Layers of Symmetric Stripline Symmetric ... Read More

Introduction In today's fast−paced and highly connected business environment, having a reliable and efficient network infrastructure is crucial for success. With the rise of cloud computing, big data, and the Internet of Things (IoT), businesses need to be able to handle large amounts of traffic while maintaining high levels of performance. One technology that can help achieve this goal is switch stacking. Switch stacking is a networking technology where multiple network switches are connected together to form a single logical unit. In other words, instead of managing each switch separately, they are managed as one entity. This ... Read More

Introduction Network monitoring is an essential part of maintaining a healthy and secure network. One critical tool for network monitoring is Switch Port Analyzer (SPAN). SPAN allows administrators to monitor and analyze network traffic by providing a copy of the traffic to an analysis device without interrupting the flow of data. In this article, we will provide an in−depth examination of SPAN, including its definition, significance in network monitoring, setup procedures and best practices, use cases, advanced features, limitations, and alternatives. Understanding SPAN Switch Port Analyzer (SPAN) is a feature available on modern network ... Read More
