Some RAM drives when used with 32-bit operating systems (particularly 32-bit Microsoft Windows) on computers with IBM PC architecture allow memory above the 4 GB point in the memory map, if present, to be used; this memory is unmanaged and not normally accessible. [2] Software using unmanaged memory can cause stability problems.
MemTest86 and Memtest86+ are memory test software programs designed to test and stress test an x86 architecture computer's random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors. [ 5] Each tries to verify that the RAM will accept and correctly retain arbitrary ...
Memory management is a form of resource management applied to computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer system where more than a single process ...
In operating systems, memory management is the function responsible for managing the computer's primary memory. [ 1]: 105–208. The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they ...
t. e. A computer program is a sequence or set [ a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [ 1] A computer program in its human-readable form is called source code.
Terminate-and-stay-resident program. A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. [1] This technique partially overcame DOS's limitation of executing only one ...
Virtual memory is an integral part of a modern computer architecture; implementations usually require hardware support, typically in the form of a memory management unit built into the CPU. While not necessary, emulators and virtual machines can employ hardware support to increase performance of their virtual memory implementations. [ 6]
These elements may include whole programs, libraries, associated configuration information, or other data. Performance may deteriorate overall as a result of such remnants, as the unwanted software or software components can occupy both hard disk memory and RAM, waste processing time, add disk I/O, and cause delays at system startup and ...
