A network link is a connection between two or more devices on a computer network. It allows data to be transmitted between the devices. You can check if a network link is active by using the ping command. If the ping command is successful, it means that the network link is active.
Network links are important because they allow devices to communicate with each other. Without network links, devices would not be able to share data or access the internet. Network links also play a vital role in the operation of the internet. The internet is a global network of computers that are connected by network links. These network links allow data to be transmitted between computers all over the world.
