Solution
The correct option is D Firewall
Firewall are used for security purpose.
A firewall is a network security system
designed to prevent unauthorized access to or from a private network. Network firewalls are frequently used to prevent
unauthorized Internet users from accessing private networks connected to the
Internet, especially intranets.
Firewall has two
network interfaces: one for the external side of the network, one for the
internal side. Its purpose is to control
what traffic is allowed to traverse from one side to the other. As the most
basic level, firewalls can block
traffic intended for particular IP addresses or server ports.
