When downloading a large file, which protocol primarily ensures that data packets arrive in the correct sequence and are acknowledged?
💡 Explanation:Transmission Control Protocol (TCP) is a core transport layer protocol responsible for reliable, ordered, and error-checked delivery of data streams. It establishes a connection, segments data, retransmits lost packets, and ensures data arrives in the correct sequence (acknowledged). User Datagram Protocol (UDP) is also transport layer but is connectionless and unreliable, prioritizing speed over guaranteed delivery. IP handles addressing and routing, while HTTP is an application layer protocol that typically uses TCP.
