Single contiguous memory management The approach to memory management in which a program is loaded into one continuous area of memory Application program Operating system Figure 10.4 Main memory divided into two sections 328 Chapter 10 Operating Systems Figure 10.5 Binding a logical address to a physical one Application program Operating system A A + L Logical address L translates to Physical address A + L we want to execute. We divide main memory up into two sections, one for each, as shown in Figure 10.4. The operating system gets what space it needs, and the program is allocated the rest. This approach is called single contiguous memory management because the entire application program is loaded into one large chunk of memory. Only one program other than the operating system can be processed at one time. To bind addresses, all we have to take into account is the location of the operating system. In this memory management scheme, a logical address is simply an
