Locking pages in memory refers to the process of preventing specific pages of memory from being paged out to disk by the operating system. This is often used for critical applications that require fast access to data and cannot afford the latency introduced by disk access. By locking pages, applications can ensure that their data remains in physical RAM, thus improving performance and stability. However, excessive use of locked pages can lead to memory pressure, potentially impacting overall system performance.
Memory manager works with pages and segments;these are different things, don't confuse them.
Demand paging is a memory management scheme that loads pages into memory only when they are needed, rather than preloading all pages at program start. This approach minimizes memory usage and allows for efficient execution of large applications by only keeping the necessary data in physical memory. When a page that is not in memory is accessed, a page fault occurs, triggering the operating system to retrieve the page from secondary storage. This on-demand loading helps optimize performance and resource utilization.
Paging is a technique with the help of which we can divide the memory into pages which help us to easly access the files and it also decreases the Execution time (Saves SYSTEM time). It also creates a mirage of Memory.
Ø In a paging system, programs and data stored on disk are divided into equal, fixed sized blocks called pages, and main memory is divided into blocks of the same size called frames. Exactly one page can fit in one frame. Physical memory is divided into parts called FRAME and logical memory is divided into parts called PAGE.
the various types of locking in vb are as follows:- 1. RdConcurReadOnly 0 (Default) 2. RdConcurLock 1 (Pessimistic Locking) 3. RdConcurRowver 2 (Optimistic Locking) 4. RdConcurValues 3 5. RdConcurBatch 4
