What is the standard that defines how to establish and maintain a network conversation over which applications can exchange data?

The standard that defines how to establish and maintain a network conversation over which applications can exchange data is known as the Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is a suite of communication protocols that enables reliable and orderly transmission of data across networks, including the Internet. It provides a set of rules and guidelines for establishing connections, formatting data packets, addressing, routing, and ensuring error-free delivery of data between devices. TCP/IP is the foundation for the modern internet and is widely used for network communications and data exchange.
