When creating network diagrams, what icon description typically represents a network firewall?

• A rectangle icon whose four arrows point in the opposite direction.
• The icon resembles the brick wall.
• A rectangular shape article that has a squiggly line on the front.
• A hockey-puck shape with two arrows on the inner side and two arrows on the outer side.

Answer:  When you create the network diagram, the icon which resembles the brick wall is the one that represents the network firewalls.

The network diagrams in the description of the computer and the network, basically it is the visual structure.it can represent the components of the network their interaction, involving the routers, hubs, firewalls.

Moreover, based on its scope and goal it has a broad level of details and also gives a broader perspective. For example, the local area network represents the individual IP address while the MAN network diagram shows the IP addresses of the buildings or the whole area with a single node. The network diagram has two types such as:

• Logical network diagram
• Physical network diagram.

Logical network diagram:

It shows the methods of how the data is moving over a network. That’s why the logical diagram represents the subnets (VLAN IDs, masks, and addresses), the devices as the router, firewalls, and the protocols of routing. The logic is related to layer 3 in the OSI model, which is known as the network layer.

Physical network diagram:

It can represent the physical organization of the components that can form the network, it includes the cables and the hardware. simply, it can show the bird’s eye view of the network.

The network diagram is used for different purposes and some of them are listed

in the following:

• It is used to make a plan of the network.
• It can update the existing network.
• It can also use to troubleshoot the problem.
• It can keep the components records/tracks.
