Answer / guest
Answer: B
A firewall is a set of related programs, located at a
network gateway server, that protects the resources of a
private network from users of other networks. An enterprise
with an intranet that allows its workers access to the wider
Internet installs a firewall to prevent outsiders from
accessing its own private data resources and for controlling
the outside resources to which its own users have access.
Basically, a firewall, working closely with a router
program, filters all network packets to determine whether or
not to forward them toward their destination. A firewall
includes or works with a proxy server that makes network
requests on behalf of workstation users. A firewall is often
installed in a specially designated computer separate from
the rest of the network so no incoming request can get
directed to private network resources.
