Need for different types of computer ports

[don52161]

Justify the need for different types of computer ports instead of one standard type of port for all devices. Please send the answer to me at dak0521@yahoo.com

without being sarcastic: because the ports have different functions. example (albiet not a computer one) try plugging a device into a 480v power socket instead of 120v and tell me why there is variety.
