Answer 1

The algorithm which replaces the block which has not been referenced for a while is called LRU.

Explanation:

• The algorithm which replaces the block which has not been referenced for a while is called LRU(Least Recently Used First).
• The Least Recently Used (LRU) algorithm is a page replacement technique used for memory management.
• According to this method, the page which is least recently used is replaced. Hence, in memory, any page that has been unused for a longer period of time than the others is replaced.
