Write the corresponding answer labels on the horizontal lines in the questions 1, the following discussion about the memory management function, A () and B () is correct. A, B: (1) even in a multiprogramming environment, users can also design the memory access program directly with the physical address. (2) the most basic task is to allocate memory for each process in order to allocate memory space, its main goal is the pursuit of improving the utilization ratio of the storage area. (3) in order to improve the flexibility of memory protection, memory protection is usually realized by software. (4) the commonly used technology exchange technology is not a modern operating system. (5) the address mapping refers to the physical address of the logical address program in the space into the memory space. (6) virtual memory physical memory capacity expansion. 2, improve memory utilization is achieved mainly by the memory allocation function (A), the basic task is to do B for each program (). Make each program in the undisturbed environment 运行,主要是通过 C ( )功能实现的. A,C:(1)内存分配.(2)内存保护.(3)地址映射.(4)对换.(5)内存扩充.
