ntp服务器地址是什么?即ntp指的是网络时间协议,主要用于同步网络中每个计算机时间协议

什么是ntp服务器?

Network Time Protocol daemon缩写为NTPD,它其实主要作为Linux系统的一个防护进程,实现了完整的NTP协议。并且NTPD和NTPDate是有根本上的区别,NTPD属于步进式逐渐校对时间,并不会出现时间跳变,然而NTPDate属于断点更新的方式。

其实在计算机使用的世界中,时间的准确性至关重要,比如火箭发射这种类型的科研活动,在对时间的准确性和统一性上要求就非常严格,若按照A台计算机运行时间,还是按照B台计算机的时间为准呢?

而NTP协议就是用来解决此类型的问题的,通过NTP协议将网络中的不同计算机时间进行统一同步方便之后的操作。NTP通过计算机的始终同步到世界协调UTC中,而精度在局域网内能达到0.1ms,在互联网中能将大多数计算机精度可达到1-50ms

使用ntp好处能使计算机对其服务器或时钟源如GPS、石英钟等进行时间同步,ntp能提供更高精准的时间矫正,同时可以使加密确认的这种方式来放置病毒协议的攻击。

通常主机是由多个时钟NTP服务器连接的,再利用统计学算法过滤来自不同服务器时间的方式,来进行最佳路径以及来源以便校对主机的时间。即使在主机长时间无法与某一时钟服务器联系的情况下,NTP服务依然可以有效运转。

以上就是关于“为什么需要使用服务器托管业务?”的相关解答,若有不清楚的可以咨询酷番云酷番云作为云南为数不错持有ICP/ISP/IDC等资质专业云计算提供商之一,成本控制良好,性价比高!提供各类云服务器产品及ICP备案一站式服务,操作简单快捷,7*24小时不间断售后运维技术支持,专业备案团队全力支持。
