How many unique IDE devices can be added to the main board of a modern system?

The correct answer is: 2

In modern computer systems, the Integrated Drive Electronics (IDE) interface typically supports up to two devices on each IDE channel. Most mainboards include two IDE channels, which results in a total of four IDE devices being manageable for newer systems. However, many contemporary systems have shifted towards SATA (Serial Advanced Technology Attachment), which allows for many more devices, reflecting changes in technology preferences. The interpretation of the question might depend on the specific context or standards referred to when mentioning "modern systems." If this context aligns with current industry standards where older conventions are still considered important, the answer provided may mistakenly suggest the limit for a single channel rather than the overall potential on the mainboard. For clarity, the value given as the answer points to a situation where only one IDE channel is being utilized effectively, while in practical terms, even older systems, if fully equipped, could handle more. Therefore, understanding the evolution of connectivity standards is essential for correctly appreciating the answer.
