Q. Suppose that you want to utilize a paging algorithm that requires a reference bit (such as second-chance replacement or working-set model) however the hardware does not provide one. Sketch how you could replicate a reference bit even if one were not provided by the hardware or explain why it isn't possible to do so. If it is probable compute what the cost would be.
Answer: You can utilize the valid/invalid bit supported in hardware to simulate the reference bit. Primarily set the bit to invalid. On first reference an entrap to the operating system is generated. The OS (operating system) will set a software bit to one (1) and reset the valid/invalid bit to valid.
