A MAC address
i would not wanna do your hw
The reason you have to use two switches (a combination of start and stop push button) on PLC is because it is how the program is written.
in STP if both switches use the same default priority, the switch with the lowest MAC address will be the root bridge.
The Destination Address (Layer 2 or Layer 3)
The network address
Modern networks used two devices for the data packets within the network will flow easily. The two devices are the routers and switches.
To check whether two switches are connected, you can use the ping command from the command line interface (CLI) of a device connected to one of the switches. By pinging the IP address of the other switch, you can determine if there is connectivity between them. If the ping is successful, the switches are connected; if it fails, there may be a connectivity issue. Additionally, using commands like show cdp neighbors (for Cisco devices) can provide information about directly connected devices.
no a bridge does not use a IP address, it uses MAC address', rousters or layer 3 uses ip address.
A Layer 3 switch uses IP addresses to make forwarding decisions. It examines the destination IP address in the packet's header to determine the best path for forwarding. Additionally, it may utilize routing tables, which contain network prefixes and associated next-hop addresses, to efficiently route packets between different subnets. This enables Layer 3 switches to perform both switching and routing functions within a network.

routers work at layer 3 (network) which usually means TCP/IP. Routing decisions are made based on a packets DESTINATION IP address.
The difference between a router and a switch has to do with the layers of the OSI model that they reside in. A switch is a layer 2 device, which means it relies on the MAC (physical) address for switching packets. A router is a layer 3 device, using the network (logical) address. A router also can forward packets to another network; a switch does not do that. In addition, a switch forwards all broadcast packets whereas a router does not forward broadcast packets.
