Routers and layer 3 switches work at Layer 3 of OSI model.
The protocol responsible for directing data to its destination is the Internet Protocol (IP). IP handles addressing and routing, ensuring that packets of data are sent from the source to the appropriate destination across networks. It operates at the network layer of the OSI model and works in conjunction with other protocols, such as TCP or UDP, to facilitate reliable communication.

A Bridge operates at 1. Physical layer: (a) divides large LAN into segments (b) connects 2 LANs that use same protocol. e.g. if the protocol is Ethernet then it can connect Fast Ethernet with Gigabit Ethernet. 2. Data link layer: (a) PDU of this layer is called frame. (b) Bridge can understand only the MAC addresses, so it forwards the frames according to their MAC addresses (unique address of NIC) to the next segment (same protocol) A bridge does not operate at net layer so it can't understand IP addresses & therefore cant recognize protocols. Thus it can't connect 2 LANs with different protocols. e.g. it can't connect Ethernet with Token Ring or FDDI. A bridge uses an interface address table to know which computers are connected to which segments. Entries in this table are SOURCE from which the bridge has received the frame & the PORT (MAC) address. By doing this it can know which computer is connected to which port Working: When a Bridge receives a frame, it checks the destination address of the frame. If the destination is present in the interface address table, it forwards the frame. If the destination is not present in the table, the bridge broadcast the frame on the all outgoing ports (except the port from which it arrived). This is called flooding.
Link layer does not understand IPs at all, it operates with MAC addresses.
A train moves backwards and forwards in a straight line along its tracks. Similarly, a piston in an engine operates in a straight line, moving back and forth to generate power. Additionally, a sliding drawer can also move in and out along its guides in a straight path.
Which? Where are the Options?WAN Technologies operate & involve Layer1, Layer2 & Layer3 of OSI Model. Example of WAN Technology Protocols are Frame Relay, ATM & X.25 protocols.
The brain is the destination for the information that is gathered by the rest of the nervous system. The nervous system operates a body's essential functions.

There is a good descrition of the network layer and TCP in the related link. NO. In general TCP and UDP are transport protocols that operates in Layer 4 Transport Layer
U.S. Southern Command (USSOUTHCOM) operates within the framework of international law, including the 1977 Additional Protocols to the Geneva Conventions, which pertain to the protection of victims of armed conflicts. These protocols enhance the protections for civilians and those who are hors de combat (out of the fight). While USSOUTHCOM is not a "party" to these protocols in the sense of signing them, the United States, as a state party, is obligated to adhere to their principles in military operations conducted by USSOUTHCOM.
