I. Introduction to Switch Certification Products

A switch, also known as a switching hub, is a network device mainly used for the conversion and forwarding of electrical signals. Its core function is to provide a dedicated electrical signal path for any two network nodes connected to the switch. Switches are typically located at the data link layer, capable of learning and storing the MAC addresses of network devices. By establishing temporary switching paths, they ensure that data packets can be directly transmitted from a source address to a destination address. This kind of equipment is widely used in local area network environments, especially when multiple devices need to communicate with each other. The switch can connect each device through wired or wireless means, thereby simplifying the configuration and management of the network.
