Firewall
Technology and networking have been advancing at a fast rate. Equally, many threats
emerge each day, and where they have become simple to spread as a result of the ability of a
particular network to communicate remotely with another through the internet. However, a
firewall is a software program that, when installed, sits in between networks so as to monitor
the incoming and outgoing data traffic against preset rules (Stewart, 2014). This means that a
firewall has to be pre-configured so as to work effectively.
A firewall has become an integral part of modern networks. Due to its security
features and monitoring capabilities, it prevents the entry of malicious data such as malware
and viruses into a network. At the same time, a firewall is an effective tool for keeping off
intruders or preventing unauthorized access to a network, and especially if well configured.
There are various types of networks. These are internal, external, and DMZ networks.
An internal network is one that is private, and where there is no communication with an
external network or devices. On the other hand, an external network is one that exists outside
the organization and may constitute of networks such as the internet. Further a demilitarized
(DMZ) network comprises a portion of a network that exposes an internal network to an
external network. In this case, a firewall may be implemented on an internal network to limit
what is availed to the DMZ network. The data in this area is exposed to other networks and
external environments, which means that it is the only data that external networks can access
in an authorized manner (Jacobs, 2016).
Router
When one connects multiple devices within an organization, this creates a network.
However, there may be a need to connect one network to another such as the connection of a

local network to the internet. In this case, a router is used. According to Cisco (n.d), a router is
a device that sits at the edge of a network, and that connects one network to another or
computers and other devices to the internet.
A router is an essential tool for a network. As briefly identified above, one network –
often created through the use of a switch – will need to link to another. This way, a router is
then necessary to create communication between these networks and the devices therein.
Further, Cisco (n.d) adds that a router is responsible for the best path for dispatching
information so as to ensure that it reaches the other network within the shortest possible time
and in the most efficient way.
There are two common types of routing. These are static and dynamic routing. Static
routing is one that involves the manual configuration of the paths that the data packets will
follow (Hartpence, 2011). As had been indicated earlier, a router is responsible for
determining the best suitable path for data packets. Static routing protocols mean that the user
dictates the path, which cannot be changed by the router. On the other hand, a dynamic
routing protocol is one that is coordinated intelligently by the switch, and where the switch
continually searches and evaluates all the possible paths to the destination while dynamically
directing data packets to the paths that are more efficient.
Switch layer 2 and layer 3
Networking has advanced significantly in the recent past. As such, it has become a
necessity for organizations and premises to connect the ever-increasing number of devices
within a particular network. A network switch is often used for this purpose. According to
Cisco (n.d), a network switch serves as a controller that enables networked devices to
communicate with each other easily and effectively. Further, a switch may be either managed,

and where the user will need to configure the switch manually, or unmanaged, and where the
switch configures itself automatically.
A switch is a necessity in the present networking environments. In this case, a switch
facilitates connection of multiple devices and exchange of data. This way, it is then possible
for various devices to communicate with one another seamlessly. Since it acts as a hub, it then
simplifies broadcasting of data within a network or routing of data in form of data packets
from one device to another.
There are two common types of switches. These are switch layer 2 and switch layer 3.
