What is an User Agent?

A user agent is a computer program that represents a person using the browser to search queries. The term user agent is quite difficult to understand for non-technical people. But, the working of a user agent is quite simple, and anyone can understand it.

Let’s understand this with an example. When we try to access a website from our browser, it sends a string (a text) to the website. The text stores some vital information, such as the browser we are using, its operating system, operating system version, and a few more critical pieces of information. After receiving the information, the website adjusts its elements according to our browser and OS version. This helps in providing the best user experience. Generally, marketers and web developers spoof the user agent to test their campaigns and designs respectively on different browsers without switching the browsers.
