it s connected by the bridge network connection
A switch forwards Ethernet frames in a LAN primarily through two functions: MAC address learning and frame forwarding. It maintains a MAC address table by learning the source MAC addresses of incoming frames and associating them with the corresponding switch ports. When a frame is received, the switch looks up the destination MAC address in its table to determine the appropriate port to forward the frame, ensuring efficient data transmission within the network. If the destination MAC is unknown, the switch will broadcast the frame to all ports except the one it originated from.

It duplicates the frame to all Ethernet ports, except the port it came from. A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
It will not forward the frame to another network

This refers to switching at layer 2 of the OSI reference model, for example, Ethernet. A switch looks at the MAC address of each Ethernet frame ("packet", you might say, but at this level the correct name is "frame"), and if it knows that this MAC address is connected at a certain port, the switch will send the information out ONLY through that port.This refers to switching at layer 2 of the OSI reference model, for example, Ethernet.

A layer 2 switch uses the MAC address to determine which port to switch the frame out of.

A switch uses frame filtering when it receives a data frame and determines whether to forward or discard it based on the MAC address in the frame's header. This process involves checking the destination MAC address against its MAC address table, which maps connected devices to their respective ports. If the address is found and corresponds to a port, the switch forwards the frame only to that port; if not, it may broadcast the frame out of all ports except the one it came from. This helps to efficiently manage network traffic and minimize collisions.
A switch floods a frame when it doesn't have the destination MAC address in its MAC address table. The frame is then forwarded out of all interfaces except the one it was received on in an attempt to find the correct host.

Each Ethernet frame sent from one computer to another includes the source and the destionation MAC addresses. It is from these addresses that the switch learns what device is connected to the port. At first, the switch won't know the destination address; in that case, it will broadcast the frame through all of its ports. But soon it learns this information. It is also possible, in some switches, to add the MAC address through configuration commands.
