What Happens When Multiple Processes Open

Linux operating system is using virtual memory to support programs running in the system. The virtual memory provides lots of optimal ways to maximize the memory mapping and utilization. The virtual memory can allocate much more memory to processes than its actual physical memory size. Linux provides virtual memory great support to allow the processes running in the system, such as mapping the process’s memory to physical memory (Arora, 2012).

Computer memory (an information storage device, a storage device) is a part of a computer, a physical device or a data storage medium used in calculations for a particular time. Memory, like the CPU, is an unchanged part of the computer since the 1940s. Memory in computing devices has a hierarchical structure and usually involves the use of multiple memory devices having different characteristics.

41-In virtual memory, programs instructions and data are divide into units of fixed size called (pages)

What is RAM? (1 point) According to our book RAM or random-access memory is a volatile, temporary storage system. It allows the processor to access program codes and data while working on a task. RAM is lost when the computer is shut down, loses power or is rebooted.

The RAM (random access memory) has a temporary memory, the computer uses it to store anything temporary. It is the computer 's main memory where programs, application software, and data are stored. The increase of RAM speeds up the computer so videos work better and applications are faster and also to give more memory to the computer.

The storage of RAM is expressed in megabytes and its capacity or size limited. An area of RAM set aside for storage of most frequently accessed information is the CACHE memory. It is a temporary high speed data holding area between the memory and the central processing unit. RAM has four parts: the conventional memory which consist of the first 640KB of RAM, used by operating system and device drivers; Upper Memory Bound (UMB) located between 640KB and 1MB of RAM, used by device drivers: extended memory (XMS) which include direct access memory above 1MB; and Expended memory: a special part of ram that is up to 32MB and exists outside the conventional memory.

20. System software is general purpose. Application software is specialized to a specific user need.

The __b__ is used to indicate that a program is permanently held in ROM (read only memory), as opposed to being held in secondary storage.

The above figures show that memory can expand to hold three, four or more programs and switch among all of them.

Memory The RAM in your system is attached on the motherboard. This is the memory that must be powered on to maintain its contents.

Resource Allocation: Modern computers are capable of running multiple programs and can be used by multiple users at the same time. Resources allocation/management is the dynamic allocation and de-allocation by the operating system of (hardware) including processors, memory pages, and various types of bandwidth to the computation that compete for those resources. Operating system kernel, in which all these functions, algorithms and services reside, is in charge of taking care of resource allocation. The objective is to allocate resources so as to optimise responsiveness subject to the finite resources available.

The computer does not use KB, MB, GB, or any other base 10 storage value of the metric system.

Other functions need to be used to segment the virtual memory pages into useful segments. Since virtual memory is allocated by pages, a number of special paging features can be used on virtual memory that cannot be used on other types of memory. For instance, pages can be locked (to prevent read/write access), or they can be protected from any particular access mode (read, write, execute).

Memory management is a process of handling computer memory to different programs to operate a system effectively. This type of
