In other words, the IP address is akin to a phone number assigned to a smartphone. TCP is then responsible for transporting and routing data through the network architecture and ensuring it gets delivered to the destination application or device that IP has defined. Both technologies working together allow communication between devices over long distances, making it possible to transfer data where it needs to go in the most efficient way possible. TCP and IP are separate protocols that work together to ensure data is delivered to its intended destination within a network. IP obtains and defines the address-the IP address-of the application or device the data must be sent to.
Its main purpose is to deliver data packets between the source application or device and the destination using methods and structures that place tags, such as address information, within data packets. IP is the main protocol within the internet layer of the TCP/IP. It does this through the Internet Protocol Suite (TCP/IP), a group of communications protocols that are split into four abstraction layers. It is the principal communications protocol responsible for the formats and rules for exchanging data and messages between computers on a single network or several internet-connected networks. IP is responsible for defining how applications and devices exchange packets of data with each other. Today, it’s considered the standard for fast and secure communication directly between mobile devices. Every device has an IP address that uniquely identifies it and enables it to communicate with and exchange data with other devices connected to the internet.
The Internet Protocol (IP) is the method for sending data from one device to another across the internet. As such, it is a good option for time-sensitive situations, such as Domain Name System (DNS) lookup, Voice over Internet Protocol (VoIP), and streaming media. UDP does not provide error connection or packet sequencing nor does it signal a destination before it delivers data, which makes it less reliable but less expensive.
TCP can be an expensive network tool as it includes absent or corrupted packets and protects data delivery with controls like acknowledgments, connection startup, and flow control. It is also used to send and receive email through Internet Message Access Protocol (IMAP), Post Office Protocol (POP), and Simple Mail Transfer Protocol (SMTP), and for web access through the Hypertext Transfer Protocol (HTTP).Īn alternative to TCP in networking is the User Datagram Protocol (UDP), which is used to establish low-latency connections between applications and decrease transmissions time. Examples include peer-to-peer sharing methods like File Transfer Protocol (FTP), Secure Shell (SSH), and Telnet. It then breaks large amounts of data into smaller packets, while ensuring data integrity is in place throughout the process.Īs a result, high-level protocols that need to transmit data all use TCP Protocol. Before it transmits data, TCP establishes a connection between a source and its destination, which it ensures remains live until communication begins. It guarantees the integrity of the data being communicated over a network. TCP organizes data so that it can be transmitted between a server and a client. It is one of the most commonly used protocols within digital network communications and ensures end-to-end data delivery. TCP is one of the basic standards that define the rules of the internet and is included within the standards defined by the Internet Engineering Task Force (IETF). It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks. Transmission Control Protocol (TCP) is a communications standard that enables application programs and computing devices to exchange messages over a network.
