    Based on the definition you just learned of Fixed I/O devices, what disadvantages do you think this type of device offers?

    Fixed devices are often built with less memory than their modular counterparts. Because fixed devices are built already containing I/O components, they have a limited number of inputs and outputs that cannot be changed.

    As a result, fixed devices are not suited for more advanced functions. Another disadvantage of the pre-assembled characteristic of the fixed devices is that repairs may be more complex.

    If one part of the system fails, it is hard to repair because the unit is assembled as one. This can lead to longer downtimes for repair.
