Introduction to I/O
The I/O (input/output) of a system refers to the devices that are used to either send data into or out of that system. Dedicated I/O modules, such as those shown in Figure 1, are connected between a computer and the peripheral devices to provide precise and real-time data flow between the two. These modules can increase the amount of data inputs into a system for flexible scalability, and sometimes even lightly process data on their own.
