Memory Management Navid Salehvaziri Virginia International University Abstract Memory management is a field of computer science that involves the act of managing computer memory to use it more efficient. That means how the computer allocate portion of memory to programs at different levels of priority to make faster program execution regard to memory space limitation. There are many techniques that are developed to reach this goal at many levels. This article try to introduce memory management levels and techniques. Especially in this article, I want to focus at of memory management of operation system level and its techniques like virtual memory that is one of the common technique that is used by many operation system to boost overall system performance. Memory Management Introduction Memory management is a technique that is used by computer system to allocate a limited amount of physical memory to processes of running user applications and operation system in a way of boost and optimize computer performance. Memory management techniques usually are deployed at three level of computer system that are: 1. Hardware memory management. 2. Operating system memory management. 3. Application memory management. In most computers all of these three level techniques are used to some extent. These are described in more details below. Hardware memory management Memory management at the hardware level is concerned with the physical devices that actually store data and programsShow MoreRelatedComputer Programming And Informational Technology1499 Words   |  6 Pagesof new STEM (science, technology, engineering and math) jobs through 2022 will be in computing† (Hoffman).
