"sends the information to a central storing place (called a database)" TIL what the word database means?
"Amazon can use your purchases to know more about you using patterns." Is this news to someone? Condescending.
"It might be connected to a network (via Internet or radio frequency)" Radio frequency and Internet are not really directly comparable
Also don't like that the site hijacks the appearance of my mouse pointer, which feels similarly disrespectful of the reader.
> Is this news to someone?
Yes, many. xkcd 1053.
