User profile

A user profile is a collection of information about a person that is stored in a computer. It usually includes a picture, name, age, email address, job, hobbies, and other personal information. When someone visits a website, they often create a user profile by entering their information into the website's database. The website can then use this information to customize their experience, such as showing them ads or other content that matches their interests.
