Your task is to implement a memory manager that manages page reads and writes from multiple client threads. In the first programming task the memory manager keeps all the pages in a memory buffer large enough to fit all the pages and the server processes a list of requests and sends them to clients to log. In the second programming task a user is allowed to specify a memory buffer size limit. The memory manager needs to place some of the pages on disk in order to cope with the buffer size limit. To do this the memory manager uses the least recently used (LRU) page replacement algorithm in order to choose which page to evict from memory when the memory is full. In the third task you extend the solution for task 1 so that requests are sent from the client to the server instead of all the requests originating in the server.
