Because each VLAN need to be on an a separate subnet, we normally need a level 3 device to lift the packages from one subnet to the other.
The simplest way of doing that is to hook up a router to the switsh, and use a so called "router on a stick"configuration. However, this is seldom done i a production environment today.
a. Router
Besides the cables themselves, each device needs a NIC interface card, and if the computers are on separate networks you need a router. Within a network you would also need a hub, switch, or bridge device.
MICE or MOUSE acts as Input device to Computer. Users can select the required area over the computer screen.
A display device such as a screen or monitor is an output device. Right from here we can already say that a display device is required to be able to visibly know what we are doing on a computer. (Even if you have a remote connection to that device you will be using a display device to view the contents of the remote device using another computers monitor.)Printers and speakers are examples of output devices. Printers are required to receive hard copies of information and Speakers are audio devices that are required to hear audible files.In short, without output devices will would not be able to view, hear, or hold data from a device.
To do that, an additional device is required, a network hub or a network switch, which all computers in the network segment should have to be connected to.
