Network Theory courses can help you learn about graph structures, connectivity, and network dynamics. You can build skills in analyzing complex systems, optimizing network performance, and understanding the spread of information or diseases. Many courses introduce tools like Python for network analysis, Gephi for visualization, and MATLAB for simulations, allowing you to apply these skills in practical work such as social network analysis, telecommunications, and epidemiology.
