A router (a piece of hardware) is just a way to move/share a connection with several other computers (i.e. using a router so that all three computers in your house can use the same internet connection) - while a firewall (usually a piece of software) is meant to block unauthorized access (hackers) to your computer/network and help protect you from viruses, spam, etc. ----- Put this way---- With a router (with default settings) in between two or more networks, hosts from any two networks can communicate accross, because router has to entertain them (no security zoning) With a firewall (with default settings) in between two or more networks, hosts from any two networks CANNOT communicate accross, because firewall MUST NOT entertain them (Security Zones) ----BTW Read these lines if you are getting interviewed----- ;)

∙ 14y agoRouter and firewall are two completely different terms in networking..
a router is a Device (H/W .. sometimes software) which routes a packet across networks. Only a router can communicate between different networks.
Eg: a packet travelling from network 'A' which is class C say 192.168.1.2
to 172.16.153.1 needs a router between it.
A firewall is software program(sometimes H/W) used to monitor and filter packets arriving and departing a Host. A firewall can be configured to allow or disallow packet transmission by an application
eg: Windows firewall , Linux Iptables
