When you use a vpn, any traffic that would go between you and a website goes through the vpn first. Makes it hard for sites to know who you are and makes it hard for your isp to know what sites you visit.
When you use tor, any traffic that would go between you and a website is bounced around between a few different computers first. Similar to a vpn but is near impossible to track unless you’re a big gov agency with lots of resources.
Checks out for me. Love me some arch and love my pour over coffee maker. Use both everyday btw.
