analyze the effect of page size in process operation and page table size, and justify a choice made for a certain page size.

simulate at algorithm level the address translation in (multi-level) paged VM system.

describe multi-level paged VM operation.

describe the general principles of implementing virtual memory (VM) together with the key concepts (paging, page table, address translation, translation lookaside buffer, page faults).
