Description: A modular switch is a networking device that allows the addition of modules to expand its capabilities, making it a flexible and scalable solution for network segmentation. Unlike fixed switches, which have a set number of ports and features, modular switches offer the ability to customize the configuration according to specific network needs. This is achieved by inserting different modules that can include additional ports, management capabilities, or even advanced functions such as security and traffic monitoring. This modularity not only facilitates adaptation to changes in network infrastructure but also optimizes resource use, allowing organizations to invest in additional capabilities only when they truly need them. Furthermore, modular switches are often more energy and space-efficient, as they allow for the consolidation of multiple functions into a single device. In summary, modular switches are an essential tool for modern network infrastructure, providing flexibility and efficiency in network management.
