virtualmemory

虚拟内存 (virtual memory) 形容词： 1. relating to or denoting a computer system in which a range of addresses can be used to access data, allowing for a program or operation to be executed even if it is not completely in the memory at one time. (指与计算机系统相关的，其中一系列地址可用于访问数据，即使一个程序或操作不是完全在内存中的情况下也能执行。) 名词： 1. a memory management capability of an operating system that uses hardware and software to allow a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage. (操作系统的内存管理功能，使用硬件和软件使计算机能够弥补物理内存短缺，将数据临时从随机存取内存（RAM）转移到磁盘存储。) 词语辨析： - virtual memory: 虚拟内存，指计算机系统中的一种内存管理技术。 - physical memory: 物理内存，指计算机实际的内存空间。 词汇扩充： - memory management: 内存管理 - address: 地址 - data: 数据 - operating system: 操作系统 - hardware: 硬件 - software: 软件 - random access memory (RAM): 随机存取内存 - disk storage: 磁盘存储 近义词： - swap space - paging 反义词： - physical memory 柯林斯词典（Collins Dictionary）解释： Virtual memory is an area of a computer's hard drive that can be used as if it were additional memory. (虚拟内存是计算机硬盘上的一个区域，可以被用作额外的内存。) 牛津词典（Oxford Dictionary）解释： Virtual memory is a memory management capability of an operating system that uses hardware and software to allow a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage. (虚拟内存是操作系统的内存管理功能，使用硬件和软件允许计算机弥补物理内存短缺，将数据临时从随机存取内存（RAM）转移到磁盘存储。) 用法： - The operating system uses virtual memory to increase the amount of memory available to programs. (操作系统使用虚拟内存来增加程序可用的内存量。) ### 例句： 1. The computer's performance improved after increasing the size of the virtual memory. 计算机的性能在增加虚拟内存的大小后得到改善。 2. Virtual memory allows programs to run even when the physical memory is limited. 虚拟内存使得即使物理内存有限，程序也可以运行。 3. The operating system utilizes virtual memory to optimize memory usage. 操作系统利用虚拟内存来优化内存使用。 4. By transferring data between RAM and disk storage, virtual memory helps maintain system performance. 通过在RAM和磁盘存储之间传输数据，虚拟内存有助于维持系统性能。 5. Insufficient virtual memory can lead to slow program execution. 虚拟内存不足会导致程序执行缓慢。 6. The virtual memory management system is a critical component of modern operating systems. 虚拟内存管理系统是现代操作系统的关键组成部分。 7. When the computer runs out of physical memory, virtual memory is used as a backup. 当计算机的物理内存用尽时，虚拟内存被用作备用。 8. Virtual memory plays a crucial role in multitasking environments. 虚拟内存在多任务环境中发挥着至关重要的作用。 9. The virtual memory address space allows for efficient memory allocation. 虚拟内存地址空间允许有效的内存分配。 10. Proper configuration of virtual memory settings can enhance system performance. 正确配置虚拟内存设置可以提高系统性能。
