TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are transport layer protocols, which means they operate at Layer 4 of the OSI model.
Layer 3 of the OSI model is the network layer, which is responsible for routing packets between different networks. This layer is where protocols like IP (Internet Protocol) operate.
Layer 5 of the OSI model is the session layer, which is responsible for establishing, managing, and terminating connections between applications. Protocols at this layer include SSL (Secure Sockets Layer) and TLS (Transport Layer Security).
Layer 6 of the OSI model is the presentation layer, which is responsible for translating data between different formats. Protocols at this layer include MIME (Multipurpose Internet Mail Extensions) and JPEG (Joint Photographic Experts Group).
Therefore, the correct answer is B, Layer 4.
