Engineering/Tip & Tech15 Threads Compared with Processes (Wikipedia 원문 보기) Threads are distinguished from traditional multitasking operating system processes in that processes are typically independent, carry considerable state information, have separate address spaces, and interact only through system-provided inter-process communication mechanisms. Multiple threads, on the other hand, typically share the state information of a single process, and sh.. 2007. 9. 29. Page Cache (원문보기 - Wikipedia) Page Cache In computing, page cache, sometimes ambiguously called disk cache, is a transparent cache of disk-backed pages kept in primary storage (RAM) for quicker access. Page cache is typically used in operating system kernels with the paging memory management, and is completely transparent to applications. All memory that is not directly allocated to applications, is usuall.. 2007. 9. 19. Demand Paging (원문보기 from Wikipedia) Demand Paging In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults wil.. 2007. 9. 19. 이전 1 2 3 4 다음
