ஃபயர்வால் தொடர்பான வித்தியாசமான கூற்று எது?

A firewall is a network-security system that monitors and filters traffic between a computer or network and the internet. It can be software, hardware, or a combination of both. It has nothing to do with physical fire; the name comes from fire walls in buildings, so 'protects the computer from fire' is the odd statement.
