In TCP connection, flags are used to indicate a particular state of connection or to provide some additional useful information like troubleshooting purposes or to handle a control of a particular connection. Most commonly used flags are “SYN”, “ACK” and “FIN”. Each flag corresponds to 1 bit information. Types of Flags:
TCP ensures that you will receive the stream of bytes in the right order, or know that you have lost communications, but it has no concept of 'packets' (or messages) like UDP does, which is why TcpClient exposes a NetworkStream. TCP (Transmission Control Protocol): TCP (Transmission Control Protocol ) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol ( IP ), which defines how computers send packet s of data to each other. Together, TCP and IP are the Technical details. ICMP is part of the Internet protocol suite as defined in RFC 792.ICMP messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations (as specified in RFC 1122). Overview of TCP/IP. TCP/IP short for Transmission Control Protocol/ Internet Protocol, is a communication protocols suite means a set of rules and procedures which are used for interconnecting various network devices over the internet by defining how the data should be transmitted, routed, broken into packets, addressed, and received at the destination. TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private computer network (an intranet or an extranet). There are two types of messages: requests sent by the client to trigger an action on the server, and responses, the answer from the server. HTTP messages are composed of textual information encoded in ASCII, and span over multiple lines. In HTTP/1.1, and earlier versions of the protocol, these messages were openly sent across the connection.
Once a connection through a TCP/IP port has been established between a TCP/IP client and a TCP/IP server, data can be sent in either direction exactly the same way that data is sent through any other type of port on a PC (serial, parallel, etc.). The only difference is that the data is sent across your network.
Jan 11, 2019 · Explanation:The TCP/IP model consists of four layers: application, transport, internet, and network access. Of these four layers, it is the internet layer that is responsible for routing messages. The session layer is not part of the TCP/IP model but is rather part of the OSI model.
Nov 13, 2018 · Short for transmission control protocol/Internet protocol, TCP/IP is a set of rules governing communications among all computers on the Internet.More specifically, TCP/IP dictates how information should be packaged (turned into bundles of information called packets), sent, and received, as well as how to get to its destination.

Feb 15, 2017 · The TCP protocol is a connection-oriented protocol, which means that a connection is established and maintained until the application programs at each end have finished exchanging messages. TCP works with the Internet Protocol (IP). TCP provides reliable, ordered, and error-free transmission. I have a TCP Server for a game that sends some messages through TCP sockets to clients: Chat messages, including chat text, chat room, and speaker. Game messages, including game actions and events. Client messages, including clients connecting, logging in, and disconnecting
