    耶...怎麼都是同一個你發問...現在才發現~^^呃...因為我記得的不多~隨便幫你解一題好了~問題二~還是建議你跑一趟成大...先幫你解決一題...加油~  ˙logical address:由CPU所產生的address。  ˙physical address:MAR裡的memory unit 所看見的address。  ˙基本上,address-binding發生在compile及load time時,兩種    address之意義沒有區別,若在execution time才做binding時就    有所不同,此時我們亦給logical address另一個名詞— virtual     address。  ˙logical address space:由一個program所產生的所有logical     address的集合。  ˙physical address space:對應到這些logical address的所有physical     address 的集合。  ˙memory-management unit(MMU):一個專門負責run-time時將    virtual address mapping到physical address的hardware device。
