I mentioned the term firewall in the terminology before this one. I might have described what a firewall is, but let’s review it again. A firewall is a defensive technology that sits between your computer and the internet.
If the firewall detects hacking in the site that you are trying to reach than the firewall will not let the info through. As before, a firewall comes in two forms, a hardware form, and a software form. If a malware manages to get through the firewall than the firewall will not let the malware out. Tip: if you chose to use a firewall, then use TWO of them at a time. That way if a hacker manages to break into the first wall than he will have trouble breaking into the other one.
