Computer Networks

Book Description

A computer network is a way for computers and other devices to connect with each other. This enables them to communicate using special rules to share data, si information and resources.

The first computer networks were created in the 1960s when huge military and university computers were joined together to share technical information. No one at the time knew where this would lead. Even just 20 years ago, no one used computer networks except at work, but now they’re everywhere. Computer networks allow people to look at websites on smartphones or tablets, send and receive emails, do their banking, shop and work from home, as well as stream videos and music from anywhere in the world onto a digital device such as a smart TV.

计算机网络是计算机和其他设备相互连接的一种方式。这使他们能够使用特殊规则进行通信，以共享数据，si信息和资源。

最初的计算机网络是在20世纪60年代创建的，当时巨大的军事和大学计算机结合在一起以共享技术信息。当时没有人知道这会导致什么。即使在20年前，除了在工作中，没有人使用计算机网络，但现在它们无处不在。计算机网络使人们可以在智能手机或平板电脑上查看网站，发送和接收电子邮件，在家中进行银行业务，购物和工作，以及将世界上任何地方的视频和音乐流式传输到数字设备 (例如智能电视) 上。
