Interactive Infographic: Layers of a Computer Network and Security

This infographic will showcase the different layers of a computer network and how they work together to ensure secure communication.

Central Image:

A stylized depiction of a computer network, with devices like desktops, laptops, and servers connected through cables and routers. Arrows will flow through the network, representing data packets traveling between devices.

Layers (Stacked Horizontally):

1. Physical Layer: Emphasize the physical cables, connectors, and wireless signals that transmit raw data bits.
2. Data Link Layer: Highlight how data is packaged into frames with addressing information for error-free transmission.
3. Network Layer: Showcase the role of IP addresses and routing protocols in directing data packets across the network.
4. Transport Layer: Depict how data is segmented into packets, transmitted reliably, and reassembled at the destination. (Optional: Briefly touch upon TCP and UDP protocols)
5. Session Layer: Illustrate how connections are established, maintained, and terminated between applications.
6. Presentation Layer: Emphasize data formatting and encryption/decryption for a common understanding between devices.
7. Application Layer: Showcase popular applications like web browsing, email, and file transfer that utilize the network layers below.

Security Icons:

Throughout the layers, incorporate icons representing security measures:

• Firewalls: Filtering incoming and outgoing traffic based on security rules.
• Encryption: Scrambled data packets for confidentiality during transmission.
• Authentication: Verification of user identity to prevent unauthorized access.
• Access Control Lists (ACLs): Defining permissions for network resources.

Interactive Elements:

• Clicking on a layer reveals a pop-up window with a detailed explanation of its function and security considerations.
• Icons can link to short animations demonstrating how each security measure operates.
• A quiz section allows users to test their understanding of the layers and security concepts.

Benefits:

This interactive infographic provides a visually engaging and informative way to learn about computer networks. Users can explore each layer at their own pace, understand how they interact, and appreciate the importance of security measures in ensuring reliable and secure communication.
