The Internet began in the late 1960s as an experiment. Its goal was to create a truly resilient information network—one that could withstand the loss of several computers without preventing the others from communicating. Driven by potential disaster scenar-ios (such as nuclear attack), the U.S. Department of Defense provided the initial funding.
The early Internet was mostly limited to educational institutions and defense contrac-tors. It flourished as a tool for academic collaboration, allowing researchers across the globe to share information. In the early 1990s, modems were created that could work over existing phone lines, and the Internet began to open up to commercial users. In 1993, the first HTML browser was created, and the Internet revolution began.
It would be difficult to describe early websites as web applications. Instead, the first gen-eration of websites often looked more like brochures, consisting mostly of fixed HTML pages that needed to be updated by hand.
A basic HTML page is a little like a word-processing document—it contains formatted content that can be displayed on your computer, but it doesn’t actually do anything. The following example shows HTML at its simplest, with a document that contains a heading and single line of text:
因特网是在1960年末在试验中诞生的。它的目标是:建立一个真实的、有弹性的信息网络——可以经受的起若干数量的电脑的崩溃,而不至于阻断其他电脑的正常通信。经得起潜在的重大灾难(如核武器攻击)。美国国防部提供了刚开始的研究基金。最早的因特网局限在教育机构和从事国防的单位。它因为作为学术研究的一种工具而繁荣,它让全球的研究人员可以彼此共享信息。到了1990初,伟大的“猫”诞生了,它通过电话线工作,从此,因特网向商业用户打开了大门。在1993年,第一个HTML浏览器诞生了,标志着因特网革命的到来。
我们很难把最早的网页称为网页程序。第一代的网页看起来更像小册子:主要由固定的HTML页面构成,这些也都需要手动修改。一个简单的HTML页面有点像一个字处理文档——它包含了格式化的内容,可以在你的电脑上显示,但是并不完成其他任何功能。上面的就是一个最简单的例子,文档包括头信息和单行文本。
一个HTML文档有两种类型的内容:文本和标记(告诉浏览器如何格式化)。这些标记很容易辨认,因为它们总是出现在之间。HTML定义了不同级别的标题、段落、超链接、斜体和粗体格式、水平线等。举个例子:某个文本,告诉浏览器用标题1的格式来显示这个文本,就是用最大的黑体字来显示。
