JCB were recommended to us by another fencing company that does not do chainlink repairs. I called JCB around 9am on a Tuesday. They arrived to our shop at around 1pm to give us a quote.
Network Hub. A network hub is designed to connect computers to each other with no real understanding of what it is transferring. Typically, a network hub is used for a private network, one that does not have any connections to sources other than local computers (meaning, no Internet access).
The basic function that any switch is supposed to perform is to receive information from any source connected to it and dispatch that information to the appropriate destination only. This thing differentiates switches from hubs. Hub gets the information and forwards that to every other device in the network.
