Page Replacement Algorithm
There are three basic page replacement algorithms: first in first out, least recently used and
Memory Management
Virtual Memory
Virtual memory is a mechanism that creates the illusion of having a very big main memory. With the concept of virtual memory, the user can store processes with size bigger than the available main memory
Segmentation
Segmentation is a non-contiguous memory management technique in which the program is divided into variable size parts called segments.
Practice question on memory management
A CPU generates 32-bit virtual address. The page size is 4 KB. The processor has a translation look-aside buffer (TLB)
Paging
In paging the physical address space of a process is non-contiguous. Paging is implemented using frames and pages.
Contiguous Memory Allocation
Contiguous memory allocation is one of the efficient and the easiest way of allocating memory to the processes. Each process is contained in a single
Memory Management
Memory management is one of the most important functions of an operating system. The working of a computer system majorly depends on two components: Memory and CPU
