Overview

Networks of computers are omnipresent. Synchronization of these computers is highly recommended at all enterprises. This integrates various diversified systems to work in unison.

Internetworking has become the backbone for communication and transportation of data and has paved way for advancement in the future.

The latest time protocol deployed in these networks is the Precision Time Protocol (PTP) & Network Time Protocol (NTP). A less complex implementation of this is the Simple Network Time Protocol (SNTP).
