Answer 2

A switch is a device that will only send a message to the device that needs or requests it rather than broadcasting it to all devices.​

What is a switch?

• In networking, a switch is a high-speed device that receives incoming data packets and routes them to their destination on a local area network (LAN).
• A LAN switch operates at the OSI Model's data link layer (Layer 2) or network layer, and as such, it can support all types of packet protocols.
• Switches serve as buffers, receiving and analyzing frames from each network segment to which they are connected.
• One useful analogy is that creating multiple VLANs increases the number of broadcast domains while decreasing the size of each broadcast domain.

As a result, a switch is a device that will only send a message to the device that requires or requests it, rather than broadcasting it to all devices.
