Which application layer protocol primarily relies on TCP for data integrity and guaranteed delivery?

💡 Explanation:

TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable, ordered, and error-checked delivery of a stream of bytes. HTTP (Hypertext Transfer Protocol), used for web browsing, relies on this reliability to ensure web pages, images, and files are transferred completely and correctly. DNS, DHCP, and VoIP primarily utilize the faster, connectionless UDP (User Datagram Protocol), where speed and low latency are prioritized over guaranteed delivery.
