Final answer:
The most latency sensitive protocol among HTTP, FTP, VoIP, and DNS is VoIP, which requires low latency to maintain high-quality voice communications.
Step-by-step explanation:
The protocol among the options given that is most latency sensitive is c) VoIP (Voice over Internet Protocol). Latency is a critical factor in VoIP communications; if there is significant latency, it can result in noticeable delays, echoes, or poor call quality during voice conversations. Unlike VoIP, protocols like HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), and DNS (Domain Name System) can typically tolerate higher levels of latency without significantly affecting user experience.
The most latency sensitive protocol among the given options is VoIP (Voice over Internet Protocol). VoIP is a telecommunications protocol that enables real-time voice communication over the internet. It requires low latency to maintain clear and uninterrupted voice communication between users. Unlike other protocols, like HTTP (Hypertext Transfer Protocol) and FTP (File Transfer Protocol), which are primarily focused on data transfer, VoIP relies on low latency to ensure good call quality.
DNS (Domain Name System) is responsible for translating domain names into IP addresses and is not as latency sensitive as VoIP. Although HTTP and FTP can be affected by latency, VoIP is the protocol most sensitive to it, as it requires real-time interaction and low delay to deliver effective voice communication.
