Abstract
Memory management of operating system is a very important research direction in computer science field. In the paper, several widely-used page-replacement algorithms are introduced and their advantages/disadvantages are analyzed. The research indictaes that LRU page-replacement algorithm is very close to the ideal one in memory management of operating system. Based on this, the principle of matrix method, which is used to realize the LRU algorithms, is introduced and discussed in detail.关键词
