There are actually more than two protocols associated with Layer 4. According to Wikipedia, there are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Stream Control Transport Protocol (SCTP), Datagram Congestion Control Protocol (DCCP), and Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX).
False.
A web browser is best associated with the application layer of the OSI Model.
Layer 5 - Session layer
Network Layer
No, At each layer, protocols perform servers unique to that layer. While performing those services, the protocols also interact with protocols in the layers directly above and below. In addition, at the top of the OSI model, Application layer protocols interact with the software you use. At the bottom, Phsyical layer services act on the networking cables and connectors to issue and receive signals.

Go to the Wiki for OSI model -that discussion and listing is very good.
Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
Application Presentation Session
DHCP runs at the application layer of the OSI model.
OSPF and RIP are used in the network layer of the ISO model.
The two main protocols associated with Layer 4 of the OSI model, which is the Transport layer, are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP provides reliable, connection-oriented communication with error correction, while UDP offers a connectionless, faster method for data transmission without guaranteed delivery. These protocols are essential for managing data flow between devices in a network.
