  • Exploring Virtual Memory

    1713 Words  | 4 Pages

    Virtual memory is an old concept. Before computers utilized cache, they used virtual memory. Initially, virtual memory was introduced not only to extend primary memory, but also to make such an extension as easy as possible for programmers to use. Memory management is a complex interrelationship between processor hardware and operating system software. For virtual memory to work, a system needs to employ some sort of paging or segmentation scheme, or a combination of the two. Nearly all implementations of virtual memory divide a virtual address space into pages, which are blocks of contiguous virtual memory addresses. On the other hand, some systems use segmentation instead of paging. Segmentation divides virtual address spaces into variable-length segments. Segmentation and paging can be used together by dividing each segment into pages.

    In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
