Internet service providers (also known as Internet service providers, Internet service providers) refer to companies that provide Internet services. Usually large telecommunications companies are both Internet providers



Define browsers and discuss URLs, HTML, javascript, AJAX, applets, and mobile browsers.

Browser is a software that can display web server or file system's HTML file (an application of Standard Generalized Markup Language), and let users interact with these files.

It is used to display text, images and other information in a world wide web or a LAN. These words or images can be hyperlinks that connect to other URLs, and users can quickly and easily browse all kinds of information. Most of the web pages are in HTML format.

The unified resource locator is a concise representation of the location and access method of resources that can be obtained from the Internet, and is the address of standard resources on the Internet. Every file on the Internet has a unique URL, which contains the information that points out the location of the file and how it should be handled by the browser.

Hyper text markup language is an application under the standard generalized markup language. It is also a specification, a standard, which marks every part of the webpage to be displayed by marking symbols.

javascript a literal scripting language, a dynamic type, a weak type, a prototype based language, and a built-in support type. Its interpreter is called javascript engine. It is a script language widely used for the client part of browser. It was first used in HTML (Standard General Markup Language Application). It is used on Web pages to add dynamic functions to HTML pages.

Ajax is a technology that can update some web pages without reloading the entire web page. By exchanging a small amount of data in the background and the server, Ajax can make the web page update asynchronously. This means that a part of the web page can be updated without reloading the entire web page.

applet is a small application written in the Java programming language, which can be included in the HTML page

Mobile browsers, also called mini browsers, mini browsers or wireless Internet browsers, are web browsers designed for mobile devices, such as mobile phones or PDA. The mobile browser optimizes the content of the web page in a small screen of handheld devices. Mobile browser software must be very small and efficient to adapt to low memory and low bandwidth of wireless handheld devices. In typical cases, they are simplified web browsers
