transport layer protocols

Transport layer protocols are rules that manage how data is sent between devices over a network, ensuring reliable communication. Think of them as the traffic controllers of the internet, directing data packets so they arrive correctly and in order. Common protocols like TCP (Transmission Control Protocol) guarantee that data reaches its destination without errors and in the right sequence, while UDP (User Datagram Protocol) sends data faster but without guaranteed delivery. These protocols help applications like emails, streaming, or chats operate smoothly by managing data flow, error checking, and retransmission if needed.
