Unit 3 – Question 1

The trail of data people leave when using the internet  refers to a digital footprint – sometimes called a digital shadow or an electronic footprint. It includes websites they visit, emails they send, and information they submit online. When people use search engines such as Google or Safari, their information is stored through the use of online cookies. A digital footprint can be used to track a person’s online activities and devices. Internet users create their digital footprint either actively or passively.
