Network security system blocking traffic
A tool (hardware or software) that checks and blocks network traffic to keep a computer or network safe from hackers and other online attacks.
Schemat użycia:
install [a firewall] on [a computer/network]
Częsty błąd:
Learners sometimes confuse a "firewall" with "antivirus" software. A firewall mainly controls network traffic, while antivirus software looks for malicious programs already on the computer. Some learners also think "firewall" is always hardware, but it can be software as well.
Synonimy
network security system (More general; can include many tools, while a firewall is one specific type of security tool for network traffic.)
Antonimy
open network (A network with little or no protection, where traffic is not filtered or blocked.)

Fire-resistant wall in a structure
A strong wall made with special materials that stops a fire from moving from one part of a building or vehicle to another part.
Schemat użycia:
build [a firewall] between [areas]
Częsty błąd:
Learners often only know the computer meaning and may not realize that "firewall" is also a physical wall in buildings or vehicles. In this meaning, it is usually used in technical or safety discussions about construction, not about computers.
Synonimy
fire barrier (Very close in meaning; may refer to any construction element that blocks fire, while "firewall" is usually a full wall.)
Antonimy
open passage (An opening or area without a fire-resistant barrier, allowing fire to spread more easily.)

Barrier separating groups or activities
A strong rule or separation that stops information or power from moving between two groups, usually to avoid a conflict of interest or unfair influence.
Schemat użycia:
create [a firewall] between [activities/groups]
Częsty błąd:
Learners may incorrectly think this use always refers to computers. In formal writing about business, media, or politics, "firewall" often means an abstract separation, not a technical device. It is not used for everyday personal boundaries; words like "boundary" or "line" are more natural there.
Synonimy
barrier (More general; can be physical or social, while "firewall" in this sense usually suggests a formal, strict separation.)
Antonimy
overlap (When roles, activities, or interests mix instead of being kept strictly separate by a firewall.)
