These advisories and warnings are based on forecast wind velocities and significant wave heights. -Wind velocity: sustained wind speeds (ten-minute average) expected over the period and area of the forecast. -Significant wave height: the average of the highest one-third of all waves observed in the local sea. Short-period waves (seas) are normally generated by the local wind, while longer period waves (swell) are generated by a distant wind source. |

Discuss the role of precise time in network sychronization.
|
Network synchronisation is an important task to get excellent performance and and quality of service
for the subscribers. In modern computer networks time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events happen. Time also provides the only frame of reference between all devices on the network. Without synchronized time, accurately correlating log files between these devices is difficult, even impossible. |
