Which type of server helps synchronize date and time across devices?

The Network Time Protocol (NTP) Server is specifically designed to synchronize date and time across devices on a network. Time synchronization is crucial in various computing environments to ensure that logs, transactions, and other time-sensitive operations are accurately timestamped.

NTP operates by allowing devices to communicate with a server that has an accurate time reference, often via atomic clocks or GPS signals. This ensures all devices within a network maintain consistent time, which is vital for the correct functioning of distributed systems, scheduling tasks, and maintaining security protocols that rely on precise timestamps.

In contrast, a Domain Name System (DNS) Server translates human-readable domain names to IP addresses to help route network traffic. A Dynamic Host Configuration Protocol (DHCP) Server assigns IP addresses to devices on a network, facilitating their connection without manual configuration. A File Transfer Protocol (FTP) Server is used for transferring files over a network, focusing on file storage and access rather than time synchronization. Therefore, the NTP Server is the clear choice for achieving synchronization of date and time across devices.
