Internet Protocols Questions Medium
TCP (Transmission Control Protocol) and IP (Internet Protocol) are two separate protocols that work together to enable communication over the internet.
IP is responsible for the routing and addressing of data packets. It provides the basic framework for sending and receiving data across different networks. IP assigns a unique IP address to each device connected to the internet, allowing them to be identified and located. It breaks down data into smaller packets and adds the necessary addressing information to each packet, ensuring that they are delivered to the correct destination.
On the other hand, TCP is a transport layer protocol that operates on top of IP. It provides reliable, connection-oriented communication between devices. TCP breaks down data into smaller segments and adds sequence numbers to each segment. It ensures that all segments are received in the correct order and reassembles them at the destination. TCP also handles error detection and correction, flow control, and congestion control to ensure efficient and reliable data transmission.
In summary, IP handles the addressing and routing of data packets, while TCP ensures reliable and ordered delivery of those packets. IP is responsible for the network layer, while TCP operates at the transport layer of the internet protocol suite.
