static linking: system libs and program code combined into the binary program image dynamic linking: link postponed until execution time OS checks if routine is in processes’ memory address Loading static loading: load the entire program, and the size of memory will be limited by the physical m...
mobile systems typically do not support swapping in any form. Mobile devices generally use flash memory rather than more spacious hard disks as their persistent storage. The resulting space constraint is one reason why mobile operating-system designers avoid swapping. Other reasons include the ...

Because the node is so slow and unresponsive, logging in to try to fix things can become impossible. Even the system’s kernel processes that are trying to fix the problem might not be able to get enough resources to run. When a node begins thrashing badly, it is often too late to fix...
This chapter describes how operating systems manage persistent memory as a platform resource and describes the options they provide for applications to use persistent memory. We first compare memory and storage in popular computer architectures and then describe how operating systems have been extended fo...
