SNTP, or Simple Network Time Protocol, is a protocol used to synchronize the clocks of computers and devices over a network. It allows devices to obtain accurate time information from a time server, ensuring that all connected systems maintain the same time, which is crucial for various applications and processes. Unlike its more complex counterpart, NTP (Network Time Protocol), SNTP is simpler and easier to implement, making it suitable for less demanding environments. It is commonly used in applications where precise timekeeping is not critical but still important for functionality, such as in IoT devices and basic networked systems.
