1.	When using counters to implement LRU, we replace the page with the ____________(a) smallest time value(b) largest time value(c) greatest size(d) none of the mentionedI had been asked this question in homework.This interesting question is from Virtual Memory topic in chapter The Linux System of Operating System
Answer» Right choice is (a) smallest time value The explanation: WHENEVER a reference to a page is made, the CONTENTS of the clock register are copied into the time-of-use field in the page-table ENTRY for that page. In this WAY, we always have the time of the last reference to each page.
