网络信息服务简称

网络信息服务简称 NIS（Network Information Service），时又译为网络数据服务协议，亦即一般简称之“黄页”YP（Yellow Pages），最早由升阳公司开发出来，为一套用来管理计算机网络中所有与计算机系统管理相关之设置文件，如用户账号、密码、主机名称或组群等的主从式目录服务协议。
由于 NIS 推出时的旧有名字 "Yellow page"“黄页”已为英国电信集团注册为该公司商业电话名录的商标，故升阳将之改名为 NIS，然而所有的指令及函数命名仍以原缩写 "yp" 为起首。
在许多环境下，已有其他目录服务比 NIS 更先进、更安全，例如 LDAP 就已经逐渐取代 NIS。
