If a motherboard lacks parallel ports needed for certain devices, what is the most cost-effective solution?

1. Replace the motherboard

2. Install a PCI card to provide the necessary ports

3. Use USB adapters for the devices

4. Connect wirelessly instead

The correct answer is: Install a PCI card to provide the necessary ports

The most cost-effective solution in this scenario involves installing a PCI card to provide the necessary parallel ports. This approach allows for the addition of the required hardware without the need to replace the entire motherboard, which is generally a much more expensive and time-consuming process. By opting for a PCI card, you can meet the demands of the devices that require parallel ports while maintaining the existing motherboard and its components. PCI cards are typically affordable, easy to install, and can expand a computer's capabilities without significant investment. Other options, while potentially viable, tend to be less practical or more costly in comparison. Replacing the motherboard not only incurs higher costs, but it may also require reinstalling the operating system and reconfiguring the system. Using USB adapters might not work well for all devices, especially if they rely heavily on parallel communication protocols or require high speed that USB may not adequately provide. Connecting wirelessly might be unfeasible for devices that inherently need a parallel connection, as they wouldn't support wireless communication unless specifically designed to do so. Therefore, installing a PCI card represents the most efficient financial and logistical choice in this situation.
