The bolt company is looking to enhance its network performance in one of its branches.
They do understand the role that is being played by different types of transmission
media in improving network performance. Furthermore, as someone who studies

network arrangement. They are looking for transmission media that will improve their
internet speed and that will be secure (i.e. protect the data being intercepted). Which
cable/media must they use and why?
