I think most standards are designed to replace multiple previous standards, but the 'port' you are talking about might be USB, which actually stands for 'Universal Serial Bus'.
The USB standard includes many devices classes, so it has become a popular replacement for lots of different previous standards, (Eg RS-232, PS2, Parallel).

Computer buses are used to reduce the number of pathways needed for signals to transmit. This can help make the computers and programs run more quickly and more smoothly.
What did Bob Taylor, who was in charge of computer science at ARPA, need to do in order to reduce the cost of different computer science projects at universities across the country?
You blew a thousand dollars on a computer. Of course you reduce no costs.
In a time sharing environment different users compete for computing time of the central computer. The computer must then schedule different users to use their fair share and that would in effect reduce the time that the computer can respond.
DE-frag your computer
To reduce the environmental impact of using a computer, you can: use energy-saving settings to reduce power consumption, turn off the computer when not in use, and recycle electronic waste properly when the computer reaches the end of its life.

we can reduce fog in lahore by turning of this computer.
Depending on how the headlight is made up, it could reduce the voltage, or reduce the number of filaments energized, or it could switch the power to different filaments which send the beam via a reflector or lens in a different direction.
to reduce you you have to find the two numbers lowest common denominator. Then that is the number that is reduced over the number you got.

they are using silicon metal for manufacturing wafer because silicon very good semiconductor for wafers . Recently they developed Single chip cloud computer (SSC)where they are saying that the effective power will reduce to 25 Watt only.
