课程名称：网络基础：打下坚实的基础 课程概述：网络是对任何希望从事IT职业的人来说最常被推荐的学习主题之一，因此，这无疑是入门时最重要的技能之一。无论你最终选择什么工作，至少对数据如何在我们周围流动有一个基础的理解是十分有益的。本课程将从数据通过物理连接的方式开始学习。 然而，仅有物理连接还不足以让互联网正常运行。我们还需要回答一些重要问题，比如：数据是如何确定确切的传输目标的？比如，当我向某人发送电子邮件时，这封邮件是如何知道要送到对方的收件箱，而不是其他人的？又或者，当您阅读这个文本和页面上储存在远离您所在位置的图像时，这一切是如何在几秒或几毫秒内传输的？ 这些迷人的问题将在我们理解互联网的物理和虚拟支柱如何工作的过程中得到解答。一旦我们理解了人类可读的信息是如何转化为机器可处理的格式，并再转回可读的格式，我们就能理解如何制定模型和标准来规定设备间的通信规则。 通过深入了解这些内容，我们将看到万物是如何相互连接的，以及互联网是如何以目前的方式运作的。加入我们，一起解开网络的神秘面纱，学习网络基础知识，这些知识将伴随您整个IT职业生涯！
About the course:Networking is easily one of the most commonly recommended topics to learn for anyone interested in being in an IT career, and so it's arguably one of the most important skills to build when starting out. Regardless of what job you end up choosing, having at least a foundational understanding of how data travels all around us is very beneficial.So in this course, we're going to learn just that starting with how data travels using physical connections. But physical connections alone aren't enough to make the internet work. We also need to answers questions like: how does data know exactly where to go? Say I'm sending an email to someone - how does that email know to go to that other person's inbox, and no one else's?Or even reading this right now. How did you receive this text and the images on this page that are stored in a different part of the world than where you're located? How does all of it transfer in seconds or even milliseconds?These are fascinating questions that can be answered once we understand how the physical and virtual backbone of the Internet works. Once we understand how human-readable information gets transformed into a format that machines can process, and then back into a human-readable format again. Once we understand how models and standards were created to dictate a set of rules for how devices should communicate.Once we look at all of that, and more, then we start to see how everything is interconnected and how the Internet is able to function the way it does.Join us as we unpack the mysteries of networking and learn Networking Fundamentals that you'll be able to carry with you throughout your entire IT career!
