A hub can send or receive information, but it can’t do both at the same time. This makes hubs slower than switches. Hubs are the least complex and the least expensive of these devices.
Switches work the same way as hubs, but they can identify the intended destination of the information that they receive, so they send that information to only the computers that are supposed to receive it. Switches can send and receive information at the same time, so they can send information faster than hubs can.

simple..just take a look of the label if its a hub or a switch..

VPN stands for Virtual Private Network.VPN provides the

Dear it should be done through the server by editing the
