What is the maximum number of PATA devices that can typically be installed on a modern ATX motherboard?

1. 2

2. 4

3. 6

4. 8

The correct answer is: 2

The correct answer is based on the standard configuration of PATA (Parallel ATA) devices in modern systems. Usually, a typical ATX motherboard is equipped with two PATA connectors, and each connector can support two PATA devices through the use of ribbon cables. This means that, under standard conditions, the maximum number of PATA devices that can be installed is indeed four, since 2 devices can connect to each of the 2 connectors. Modern ATX motherboards have transitioned towards SATA (Serial ATA) technology due to its superior speed and efficiency, resulting in a reduced emphasis on PATA connections. However, if the question is specifically relating to the number of devices connected, then the realization must be that while the maximum number of devices is four, each channel directly refers to its ability to support additional devices. Thus, the first options are important to understand the context of the PATA standard. In summary, while it might seem straightforward, recognizing the correct capacity of PATA connectors leads to the realization that each channel hosts 2 devices, making the total number maximum at four rather than any of the options that suggest fewer or more connections.
