Well brace yourself, soon systems such as the above will be but a bad memory of days gone by.
Current computers send their data by way of electrical signals.
These signals are actually free electrons traveling down wires. The solution to this problem is photonics. Photonics uses photons to send large amounts of data quickly. Photons, which are uncharged particles of light, are superior to electrons for moving data at high speeds. The photons are carried over optical fiber that has virtually no loss, providing a potential capacity of 500 terabytes per second.
