问题:
IT行业与其他行业有什么特点?

回答:
IT是信息技术的简称，Information Technology,指与信息相关的技术。不同的人和不同的书上对此有不同解释。

IT实际上有三个层次：
{dy}层是硬件，主要指数据存储、处理和传输的主机和网络通信设备；

第二层是指软件，包括可用来搜集、存储、检索、分析、应用、评估信息的各种软件，它包括我们通常所指的ERP(企业资源计划)、CRM(客户关系管理)、SCM(供应链管理)等商用管理软件，也包括用来加强流程管理的WF(工作流)管理软件、辅助分析的DW/DM(数据仓库和数据挖掘)软件等；

第三层是指应用，指搜集、存储、检索、分析、应用、评估使用各种信息，包括应用ERP、CRM、SCM等软件直接辅助决策，也包括利用其它决策分析模型或借助DW/DM等技术手段来进一步提高分析的质量，辅助决策者作决策(强调一点，只是辅助而不是替代人决策)。

有些人理解的IT把前二层合二为一，统指信息的存储、处理和传输，后者则为信息的应用；也有人把后二层合二为一，则划分为前硬后软。

可惜他在IT这一概念上是经常含混不清：一会儿指主机网络，一会儿又跑到软件.
