Which is an explicit example of time synchronization technology?

• A. Domain Name System (DNS)
• B. Network Time Protocol (NTP)
• C. File Transfer Protocol (FTP)
• D. Dynamic Host Configuration Protocol (DHCP)

Answer: (B)

Time synchronization technology focuses on keeping clocks across different devices aligned so events and logs can be accurately correlated. Network Time Protocol does exactly that: it provides a standardized way for systems to obtain precise time from reliable sources and adjust their local clocks accordingly, using a structured hierarchy of time servers and algorithms that minimize drift. This makes it the explicit example of a time synchronization technology, since its primary purpose is to synchronize clocks across a network. Other common network services serve different functions. Domain Name System translates human-friendly names into IP addresses, FTP handles transferring files, and DHCP assigns IP addresses and related configuration to devices. While their operations may include timestamps in some contexts, their main roles are not about keeping system clocks in sync, so they don’t illustrate time synchronization technology.
