Understanding a noun: User agent

Wen/Binghaibin

Original:

The term User agent and the lack of understanding what a user agent is can also be a problem.
Normally, the user agent is a browser like Microsoft Internet Explorer (MSIE), Netscape,
Mozilla (Moz), Firefox (Fx), Opera, or Safari. However, browsers are not the ' only user ' agents on
The Web. Others include
Assistive technology that helps users to overcome the limitations of a disability-like
Text-to-Speech software or Braille displays
text-only agents like Lynx
web-enabled Applications
Game Consoles
Mobile/cell Phones
PDAs
Interactive TV set-top boxes
search engines and other indexing programs
and many more
This large variety of the user agents, of different technical finesse (and old user agents
Don ' t get updated), are also a great danger for JavaScript.

Translation:

The term User agent and the lack of understanding of what a user agent is is also a problem. Typically, a user agent refers to a browser, such as Microsoft Internet Explorer (MSIE), Netscape,mozilla (Moz), Firefox (Fx), opera, or Safari. However, the browser is not the only user agent on the web. The other include:

N Assistive technology to help users overcome their flaws-such as text-reading software or a blind display

n Plain Text web browsers, like Lynx

n Web-activated applications

N Game console

n Cell phone/cellular phone

N Handheld Phone (PDAs)

N Interactive TV set-top box

N Search engines and other retrieval programs

n More of the other

So many types of user agents, different technical means (some old user agents are not updated), is also a very large risk for JavaScript.
