white-space: normal; background-color: rgb(255, 255, 255); text-align: left;">信息技术的应用主要包括计算机硬件和软件、网络和通讯技术、应用软件开发工具等。自从计算机和互联网普及以后，人们开始普遍使用计算机来生产、处理、交换和传播各种形式的信息，如书籍、商业文件、报刊、唱片、电影、电视节目、语音、图形、影像等等。</p><p style="-webkit-tap-highlight-color: transparent;

white-space: normal; background-color: rgb(255, 255, 255); text-align: left;">具体来讲，信息技术主要包括以下几方面技术：</p><p style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; margin-top: 16px; margin-bottom: 16px; padding: 0px; color: rgb(34, 34, 34); font-family: &quot;PingFang SC&quot;, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, &quot;WenQuanYi Micro Hei&quot;, &quot;Helvetica Neue&quot;, Arial, sans-serif;

white-space: normal; background-color: rgb(255, 255, 255); text-align: left;">这种技术的主要作用是扩展人获取信息的感觉器官功能，主要包括信息识别、信息提取、信息检测等技术。此类技术也被总称是“传感技术”。它几乎可以扩展人类所有感觉器官的传感功能。传感技术、测量技术与通信技术相结合，从而产生了遥感技术，这就更加使得人类感知信息的能力得到了增强。信息识别包括文字识别、语音识别、图形识别等。</p><p style="text-align:center"><img src="http://p3.pstatp.com/large/pgc-image/ebc3b825e15e4192bb5a78063df0e084" img_width="916" img_height="340" alt="什么是信息技术？" inline="0" style="-webkit-tap-highlight-color: transparent;
