Buying used computer – any identifying hardare specs sent when surfing web?

this is one of those “Things I should know and was afraid to ask” questions.

I’m considering buying a used laptop for the first time – and I had a thought – even if I wipe the hard drive and re-install an OS (probably a Linux distro) from scratch, does any indentifying information about the hardware get sent to servers when visiting web sites? Probably not your average website – but those pesky ad trackers are getting pretty sophisticated at finding identifiable bits. As in, if the previous owner had been up to questionable activities, do I now look to sophisticated trackers like I’m the same laptop just with a new OS and IP?

I’m 90% certain not. Just checking to be sure.

Thanks.
