You’ve probably heard the term “firewall” before. When you hear this term, you most likely think of computer protection systems, and that these systems keep hackers from getting info off your computer or out of your browser history. What you probably don’t think of is the origin of the use of the term “firewall” in PC security.
This term originates from construction. There are fireproof walls that are typically put between stores in strip malls and residences in residence complexes. These walls, exactly like firewalls on computers, are safety measures. If one piece of the building catches aflame, a firewall will keep the fire from destroying the whole building.
These can be put up in houses, as construction companies like Utah builders could tell you, but it is not done quite often, as folks rarely wish to pay for the expense of adding firewalls between rooms. They’re very pricey and also extraordinarily heavy.
Usually, in houses, the only places you might find firewalls are in garages or basements, as these are where the electric power breakers are. Just to have a firewall, they must be permitted by the building codes, and not all building codes will permit firewalls in houses.
It’s possible that you’ve seen firewalls before. It could be there was a fire at the strip mall up the way, and one of the parts of the building is now gone, but the big (normally grey) walls on both sides of the building are blackened but still standing, and have quite obviously protected the remainder of the building. Those walls are the firewalls, and if you see this actual scenario, then they have done their job well. Whole buildings could burn to the ground without firewalls, and even companies like Utah home builders, which seldom use firewalls, will sometimes suggest installing them.
