Computer Learning

[Phil(Hot Rod Chevy)]

MM,

How does a hardware firewall work?

The "hardware firewall" is a router, but in essence a "hub".

All of my computers are connected to the router. The router is connected to my cable modem.

The router is considered a firewall because my computers are not visible to the scanners the hackers use while looking for open ports.

Or so I am told.

How does it determine which sites are permitted access and which sites are denied?

It cannot determine whether or not sites are permitted, because it is simply a "pipe" to the internet, and also allows me to access any computer's data or components from any other.(on my network)

Does the process slow down incoming data?

It does not slow down the system.

Have fun,
Phil
