COMPUTER NETWORKING

Detailed explanation-1: -In the Open Systems Interconnection (OSI) communication model, UDP is in Layer 4, the transport layer.

Detailed explanation-2: -The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net-work, transport, and application layers.

Detailed explanation-3: -All the protocols that are part of the Internet standards are organized into a 4/5-layer protocol stack. Each layer in the protocol stack correspond to a level of abstraction.

Detailed explanation-4: -Stream Versus Packet-TCP/IP is a stream-oriented protocol, while UDP is a packet-oriented protocol. This means that TCP/IP is considered to be a long stream of data that is transmitted from one end of the connection to the other end, and another long stream of data flowing in the opposite direction.
