It is based on the locality model of program execution. shared by several processes. The virtual memory manager will deal with two types of addresses, so it is convenient to give them names. Memory allows You to use a portion of your hard drive as though it were part of physical! 10001 W Penticton Drive Since, a part of the program needs to be in memory for the process of execution, the logical space can therefore be much larger than the physical address space. The purpose of cache memory is to keep handy the most recently accessed data and instructions so that the CPU can access them repeatedly without wasting time. 1. With the help of virtual memory, we can load or store the large size processes than the available memory.
