Description


Hello there,

Welcome to “Networking | Network Fundamentals, Wireshark & Packet Tracer” course

Mastering Networking with Network Fundamentals, Wireshark Network Analysis and Cisco Packet Tracer Network simulations


Networking, or computer networking, is the process of connecting two or more computing devices, such as desktop computers, mobile devices, routers or applications, to enable the transmission and exchange of information and resources.

Networked devices rely on communications protocols—rules that describe how to transmit or exchange data across a network—to share information over physical or wireless connections.


Wireshark is a widely used, open source network analyzer that can capture and display real-time details of network traffic. It is particularly useful for troubleshooting network issues, analyzing network protocols and ensuring network security. Networks must be monitored to ensure smooth operations and security.

Wireshark 's main function is to help analyze the traffic on any network of your choice regardless of size.


Cisco Packet Tracer is a comprehensive, networking technology teaching and learning program that offers a unique combination of realistic simulation and visualization experiences, assessment and activity authoring capabilities, and opportunities for multiuser collaboration and competition. The innovative features of Packet Tracer help students and teachers collaborate, solve problems, and learn concepts in an engaging and dynamic social environment.

Packet Tracer is a simulation, visualization, collaboration, and assessment tool for teaching networking.

It allows students to construct their own model or virtual networks, obtain access to important graphical representations of those networks, animate those networks by adding their own data packets, ask questions about those networks, and finally annotate and save their creations.

Frequently asked questions

What are the basics of IT networking?

IT networking covers the fundamental concepts of how devices communicate within a network, including IP addressing, subnetting, and network protocols.


What is the meaning of packet capture?

It is the process of intercepting a data packet that is moving through a network. The data packet helps in network analysis that is by analysis the data one can know the security status of the net.


Explain packet sniffers or network analyzers work?

Packet sniffers work by intercepting into a network that they can "see." What a packet sniffer can capture depends on the structure of the net. Ones a packet sniffer or network analyzer captures a packet they analyze it and present it in human readable form so that the user of packet sniffer can make use of the data.

It is wise to note a packet sniffer gets set into two ways. Some can be configured to capture all the data in this way we say they are unfiltered. There are those that are set to capture specific packets. We describe them as filtered.


What is the standard software tool that is used for packet sniffing or network analysis?

The most known network analysis or packet sniffing tool is called WireShark. It was known as Ethereal in the past and gathered datagram in real time have them in a form that you can read. It has color coding, filters, and other great features. It helps you analyze individual data packets and helps you go deeper in network matters.


What is Cisco Packet Tracer used for?

Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.


How can I obtain Cisco Packet Tracer?

Cisco Packet Tracer is available free of charge to all Cisco Networking Academy instructors, students, and alumni.
