Network Time Protocol

The Network Time Protocol is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency information networks. NTP uses UDP port 123 as its transport layer. It is designed particularly to resist the effects of variable latency. NTP is one of the oldest Internet protocols still in use. NTP was originally designed by Dave Mills of the University of Delaware, who still maintains it, along with a team of volunteers.

Prevention

In medicine, prevention is any action which reduces the burden of mortality or morbidity from disease. This takes place at primary, secondary and tertiary prevention levels.Primary prevention avoids the development of a disease. Most population-based health support activities are primary preventive measures.Secondary prevention activities are aimed at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and reducing disease-related complications.
