We may add the information in ascending order by using a bit based on multiple charges each reference period, such as the 8-bit (1 byte) per page (the page table) and every interval (eg, every 100 milliseconds. second) clock is set to send a signal to interrupt the operating system bit shift reference (8 bits) of each face to the right one bit (shift right), so the data from the bit reference 8 bits shows a reference to that other. during the past eight bits, if the reference is 00000000, indicating that this page has not been referenced as 8 moments ago. If the reference bit is 11111111, the page is referenced at least one time every eight hours during the past period.
