virtual storage 虚存,虚拟存储器;[虚储存器] The storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped into real addresses. Note: The size of virtual storage is limited by the addressing scheme of the computer system and by the amount of auxiliary storage available, and not by the actual number of main storage locations. 一种存储空间,计算机系统的用户可将其看作是可寻址的主存储器。在这种计算机系统中,虚地址映象变换 成实地址。注: 虚拟存储器的大小受限于计算机系统的编址方案以及可用辅助存储器的大小,而与主存储单元的实际数目无关。 |
