TCP/IP, in full Transmission Control Protocol/Internet Protocol, standard Internet communications protocols that allow digital computers to communicate over long distances.

TCP/IP is the common transport protocol of the Internet and is a set of layered protocols, providing a reliable data transport mechanism between machines. ... The most basic difference between MODBUS RTU and MODBUS TCP/IP is that MODBUS TCP/IP runs on an Ethernet physical layer, and Modbus RTU is a serial level protocol.

That's where protocols such as the Transmission Control Protocol (TCP) come in. TCP is used in conjunction with IP in order to maintain a connection between the sender and the target and to ensure packet order. For example, when an email is sent over TCP, a connection is established and a 3-way handshake is made.

TCP/IP. In TCP/IP, the application layer contains the communications protocols and interface methods used in process-to-process communications across an Internet Protocol (IP) computer network.

An internet protocol (IP) address allows computers to send and receive information.

DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an Internet Protocol (IP) address to any device, or node, on a network so they can communicate using IP.

TCP/IP is the older of the two approaches to data communications and is well established throughout the world. The OSI model, however, is a proven concept that is used in all other data communications protocols. It will continue to be used as a guideline for all other communications applications.

2. Ethernet Basics. TCP/IP (Transmission Control Protocol/Internet Protocol) is a set of protocols independent of the physical medium used to transmit data, but most data transmission for Internet communication begins and ends with Ethernet frames. The Ethernet can use either a bus or star topology.

Protocol is currently defined to use TCP as its transport protocol. In the future SCTP is going to be supported as transport protocol as well. IANA-assigned port number for AMQP is 5672 (TCP, UDP, SCTP).

TCP congestion control. Transmission Control Protocol (TCP) uses a network congestion-avoidance algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, along with other schemes including slow start and congestion window, to achieve congestion avoidance.

HTTP uses TCP because the files, images, web pages which we get from the remote host should not be dropped on the way and it should be delivered in order to the HTTP client. HTTP could also use UDP but usually not, if a UDP packet containing the first part of a web page is lost, then its not retransmitted.

In computer science, an Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

TCP/IP uses IP addresses to communicate, and a DNS server resolves oblect to IP addresses for all the transmission based items your network needs to communicate with, like PC's, servers, printers, etc. A domain controller on the other hand holds all of the other information about everything in your network.

The Internet Control Message Protocol is an internet layer protocol used by network devices to diagnose network communication issues. ICMP is mainly used to determine whether or not data is reaching its intended destination in a timely manner. Commonly, the ICMP protocol is used on network devices, such as routers.
1151137
ICMP messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations (as specified in RFC 1122). ICMP errors are directed to the source IP address of the originating packet.

SFP ports and their corresponding SFP modules are used to facilitate seamless, high-speed internet connections over extended distances in a variety of applications. They're often used to connect one gigabit network switch to another, which, in turn, increases the size and improves the functionality of a network.

Ethernet is a local area technology, a protocol for the Network Layer within the TCP/IP stack. On the other hand, TCP/IP is a protocol suite which are used in the OSI layers for efficient networking between each layer.
