In a scenario where high bandwidth and resistance to EMI are both crucial, which networking media should be chosen?

When both high bandwidth and resistance to Electromagnetic Interference (EMI) are crucial, the best choice for networking media would be fiber optic cables.

Here's why:

1. High Bandwidth: Fiber optic cables have a much higher bandwidth than metal cables. This means they can carry more data than metal cables of the same diameter. In the context of Internet, more bandwidth means faster speed.

2. Resistance to EMI: Fiber optic cables are also highly resistant to Electromagnetic Interference (EMI). Unlike metal-based cables, which can suffer from interference due to electromagnetic fields from nearby electronic devices, fiber optic cables transmit data in the form of light, so they are not affected by EMI.

So, in a scenario where both high bandwidth and resistance to EMI are crucial, fiber optic cables would be the best choice.
