什么是数据网络？(a data network?)
数据网络是一种电子通信过程，允许有序地传输和接收数据，如信件、电子表格和其他类型的文档。将这种类型的网络与其他形式的通信（如音频网络）区别开来的是，它被配置为仅传输数据。这与通常用于语音通信和数据传输（如传真传输）的音频或语音网络形成对比。
目前有两种基本类型的数据网络在运行。专用网络本质上是一个本地网络，其设计允许在给定实体（如公司）内的各个部门之间传输数据。公司的所有位置都可以作为网络上的节点，并且能够通过一个通用服务器进行通信，该服务器充当整个业务中使用的任何和所有数据文件的存储库。还有一些私有网络的例子，它们允许属于同一专业或行业的多家公司之间共享数据。可以通过创建驻留在主服务器上的虚拟专用网络（VPN）或通过通信运营商提供连接来实现连接。
与专用数据网络相比，公共网络将广泛地可供给定运营商网络的住宅和公司客户访问。此类网络的设置可能涉及使用多台服务器，并通过几个不同的过程连接到网络。通常，网络将需要某种类型的订阅过程，如每月使用费。在收到费用后，服务提供商将允许创建访问凭据，以允许消费者访问网络的授权部分，并参与通常涉及数据的多个功能。这些功能包括检索存储文档、创建重要数据文件的备份以及归档数据（如历史信息或其他对未来应用程序有价值的数据）。
