Ntp - the need for accurate time
Typically for this type of mechanical or digital watch timing closer to us and accuracy. A digital watch may be more about losing second place d weeks and I am sure that you also won t Translated from both angry if you delayed the arrival of moving. However, when it comes to sending information over a network, satellite control, or even buy shares in the stock market is more accurate when necessary. Computer network depending on the precision time for almost all applications, from sending emails to store data, when the seal is important to keep a list of computers. Switch routers also need to run all the same level, the Sync device can cause data to be lost and even entire connections. For satellite navigation, long used by ships and airlines, but now increasingly popular in modern vehicles, the accuracy millisecond (thousandth of a second) is important as light (and therefore radio waves) can travel 300 km in the time that any small error in time will mean that the accuracy of satellite navigation signals may be hundreds of miles. Computer networks need not only synchronized but when their sensitive transactions with other networks, computers or via the Internet also requires synchronization. Imagine a bid on eBay and make efforts to end only with computers running on a variety of auction houses is to identify the beginning as one of the last bidder, you must be upset. For this reason a global standard that is used to allow a small computer in the world to synchronize to the same source. This is a small international UTC (Coordinated Universal Time). UTC time is based International Atomic Time (eagle), which is the time as told and international agreements Atomic Clocks (260 in 40 different laboratories around the world) where the average is taken for Tai accurate within one second every three million years. UTC time leap second added (or taken away) every year or more to compensate for the reduction (and stay on) of the rotation of the Earth as a true planet under 100.000 that is more reliable than nuclear and on without end Leap seconds what that night (at least for 40.000 years or more). Computer using a protocol called NTP (Network Time Protocol) which can receive signals either UTC time through the Internet or through a professional radio transmissions from the physics lab or through the GPS network. NTP server and ensure that all devices connected to the network are synchronized to UTC to allow computers to communicate across the world and each well.
