It is software that acts as a bridge between you, the user, and the internet. The easiest way to understand user agents and their benefits is to look back at the development of the web. When the internet was a text-based system, early users had to enter commands to navigate and send messages. Today, browsers do that for us. We simply point and click, and the browser acts as our "agent," turning our actions into commands. When your browser (or a similar device) loads a website, it identifies itself as an agent while retrieving the content you requested. Along with this user-agent identification, the browser sends a great deal of information about its device and network. This is valuable data for web developers because it lets them customize the experience according to the user agent loading the page. Types of user agents Browsers are a simple example of user agents, but other tools can also act as agents. Crucially, not all user agents are controlled or directed in real time. Search engine crawlers are a good example of largely automated user agents: bots crawl the web without user control. Here are some user agents you may encounter: Browsers: including Internet Explorer, Firefox, Safari, Chrome, Edge, BlackBerry, Opera, Minimo, Beonex and the AOL browser. Crawlers: Google, Google Images, Yahoo! lur喝, and hundreds more. Consoles: the built-in browsers of PlayStation 3, Wii, PlayStation Portable and Bunjalloo-Nintendo DS. Legacy operating systems (such as AmigaVoyager). Offline browsers and browser-like applications (such as Wget and Offline Explorer). Link checkers (such as W3C-checklink). Plus various feed readers, validators, cloud platforms, media players, email libraries and scripts.
