What is the browser? Browser Common Sense Introduction

What is the browser? General introduction to browser knowledge

The Global Network (WEB,WWW) is an attempt to organize all the information on the Internet, including local information that you are willing to add, into hypertext files, forms of documents. Although the dream may be a bit unrealistic, the global network does give you access to all the resources on the internet, just "read" the appropriate files in the browser.

A browser is a translation of text documents (and other types of files) found on the Internet into Web pages. Web pages can contain graphics, audio and video, as well as text; As a result, the web has sparked interest in the formerly text-based Internet.

A browser is an application on your hard disk, just like a word processor (such as WordPerfect or Microsoft Word).

HTML is the formatted language on which the network is based.

The HTML document looks very different from the Web page displayed on the browser. The Web page you see on the screen is the browser's translation of HTML documents.

The images you see are called by HTML documents, but they are not part of it-they are separate documents.

The browser reads the location of the images from the HTML code and places them on the Web page.

Similarly, audio or video files are called by HTML files and then assembled by the browser.

The cache of browsers is another important factor:

Because documents on the Web take time to download, browsers can temporarily store images on your hard disk to avoid downloading the same files repeatedly. The cache can and should be emptied at least once every four or five hours.
