Handling I/O operations. Client B. Example: Suppose (consider above example) three process p1, p2, p3 comes with size 2MB, 4MB, and 7MB respectively. memory is partition into 5 regions the region is reserved for updating system the remaining four partitions are for user program, once partitions are defined operating system keeps track of status of memory partitions it is done through data structure called partition table, an address generated by CPU is commonly referred to a logical address. Memory management Virtual Memory Multitasking. The hardware implementation of the page table can be done by using dedicated registers. The harder task is to handle all processes and tasks. A virtual cache uses a portion of physical memory to store code and data that the operating system might use frequently. Cache controllers predict which pieces of data the CPU will need next and pull it from main memory into high-speed cache to speed up system performance. This is accomplished by swapping unused resources out of physical memory and replacing them with those required to execute the current operation. In the operating systems two types of fragmentation: Internal fragmentation occurs when memory blocks are allocated to the process more than their requested size. Another way to boost performance is to use a virtual cache. A swapping allows more processes to be run and can be fit into memory at one time. C) the currently active part of an application. Application software are the type of software designed to meet the requirements of users to perform specific tasks. In a multiprogramming computer, the operating system resides in a part of memory and the rest is used by multiple processes. B. Android When the keystroke arrives, the OS changes its status.
