Switches are presented in several types. Ethernet-switches are utilized in large-scale multi-device setups that are connected into one grid. Network switches are effective due to their ability to relay the signal only to those users who are supposed to receive it, thus efficiently using the traffic and preventing the grid from collapsing due to irrelevant data blocking all feeds. DVI-switches are utilized mostly in offices and small advertising networks. They are used to relay data from one monitor to other displaying devices. DVI appliances are digital, so there’s no quality loss. KVM-switches are utilized in complicated control set-ups. With the aid of such utilities an operator can control several PCs or stands using only one set of control devices (a keyboard, a monitor, a mouse).
