>>361538Ill try and be pretty simple, when you use a VPN, before your Internet traffic leaves your computer, it gets encrypted in such a way that your ISP can't understand it. Then it gets send to a large datacenter where your traffic is unencrypted and send out to wherever it needs to go, it works in reverse too, so when you download something it goes to your VPNs datacenter first, gets encrypted, then it gets sent to your computer, and decrypted.
A VPN stops your ISP from being able to understand what you're doing on the internet because they only see encrypted data from you. To use a VPN you would install a program like openVPN on your PC, openVPN works with pretty much any VPN, all you need to do is enter your VPNs password and that's it.
>chrome uses something called bot netbotnet is a term for services that take telemetry, and data from you, like what websites you visit, and what stuff you do online , and either sell it to 3rd party company's or use it for targeted advertising. Google makes most of it's income from advertising, mainly by seeing what you search and giving you ads related to that product.
Windows is notorious for being a "botnet", they take everything you do on your OS and sell it. It's not bad to use chrome, if you've already been using it for years there's no need to switch. But if you want to try something new , go with Firefox.
