user available memory

基本解释

If a mouse is installed in a computer, then the available memory space of user will reduce.
如果計算機安裝了鼠標，用戶可利用的內存空間就會減少。
If additional datapoints existed after this user count, no additional memory was available to process the additional users.
如果在這個用戶數量外還存在額外的數據點，那麽就沒有額外的內存用於処理額外的用戶。
Lotus Domino begins using the first two available segments for user heap memory (0x3 and 0x4). Lotus Domino begins using the last segment (0xF) for shared memory.
Lotus Domino 最初將前兩個可用的段（0x3 和 0x4）作爲用戶堆內存，將最後一個段（0xF）作爲共享內存。
