The term I/O means “input” and “output” and are the fundamental idea behind computers. Basically, for every input, there’s an output. You pull up a document on your computer and use the keyboard to print it. The keyboard is the input and the printer is the output. This is a simple explanation of I/O, but it’s a good start to help explain what I/O cards are and how they work.
The ports on your laptop or desktop computer are also known as I/O imports for the same reason – you plug in a USB cord, controller, or other peripheral device, which is the input. What the device controls is the output.
So what are I/O Cards?
When you look at an I/O card, you’ll probably think it resembles a circuit board – that’s because it is! This board plugs into a slot on the motherboard of a computer so it can control a peripheral device like a controller or mouse.
I/O cards are also called interface cards, adapters, or controllers. In addition they might be referred to as expansion cards, because they expand the capability of a computer or laptop. Of course, these cards are also used in an industrial capacity and are much larger and more complex than those used for personal computers.
How Do They Work?
I/O cards function as a bridge between a computer and an outside device – this can range from a monitor to a keyboard. The outside device transmits a signal to the I/O card which results in an action being performed.
The part of the I/O card that faces out can accept a variety of different devices and cables. While some cable inputs might be as simple as a USB plug, industrial size I/O cards may be customized to accept specially designed plugs and devices.
When an I/O card is damaged, there is a disconnect with the device, which can cause errors and downtime. Damage can occur in a variety of ways, and much like circuit boards, I/O cards can be repaired or replaced, depending upon the amount of damage they have sustained.
