物联网是什么?

摘要:物联网定义
物联网是新一代信息技术的重要组成部分,也是“信息化”时代的重要发展阶段。其英文名称是:“Internet of things(IoT)”。顾名思义,物联网就是物物相连的互联网。这有两层意思:其一,物联网的核心和基础仍然是互联网,是在互联网基础上的延伸和扩展的网络;其二,其用户端延伸和扩展到了任何物品与物品之间,进行信息交换和通信,也就是物物相息。物联网通过智能感知、识别技术与普适计算等通信感知技术,广泛应用于网络的融合中,也因此被称为继计算机、互联网之后世界信息产业发展的第三次浪潮。物联网是互联网的应用拓展,与其说物联网是网络,不如说物联网是业务和应用。因此,应用创新是物联网发展的核心,以用户体验为核心的创新2.0是物联网发展的灵魂。
