A patch panel is a device used in networking to organize and manage the connections between computers, servers, and other network devices. It typically consists of multiple ports where network cables can be plugged in, allowing for easy access and organization of network connections. Patch panels help to streamline network configuration, troubleshoot issues more efficiently, and maintain a neat and organized network infrastructure. They are commonly found in server rooms, data centers, and other networking environments where multiple devices need to be connected and managed.
