  2. Memory management - Wikipedia

    en.wikipedia.org/wiki/Memory_management

    Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) 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.

    The Linux kernel System Call Interface (SCI), aims to be POSIX/SUS-compatible [3] Process scheduling subsystem IPC subsystem Memory management subsystem Virtual files subsystem Networking subsystem Other components: ALSA, DRI, evdev, klibc, LVM, device mapper, Linux Network Scheduler, Netfilter Linux Security Modules: SELinux, TOMOYO, AppArmor ...

  4. Memory management (operating systems) - Wikipedia

    en.wikipedia.org/wiki/Memory_management...

    Single allocation is the simplest memory management technique. All the computer's memory, usually with the exception of a small portion reserved for the operating system, is available to a single application. MS-DOS is an example of a system that allocates memory in this way. An embedded system running a single application might also use this ...

  5. Operating system - Wikipedia

    en.wikipedia.org/wiki/Operating_system

    Cooperative memory management, used by many early operating systems, assumes that all programs make voluntary use of the kernel's memory manager, and do not exceed their allocated memory. This system of memory management is almost never seen anymore, since programs often contain bugs which can cause them to exceed their allocated memory.

  6. Slab allocation - Wikipedia

    en.wikipedia.org/wiki/Slab_allocation

    partial – slab consists of both used and free objects; full – all objects on a slab marked as used; Initially, the system marks each slab as "empty". When the process calls for a new kernel object, the system tries to find a free location for that object on a partial slab in a cache for that type of object.

  7. Accounting information system - Wikipedia

    en.wikipedia.org/wiki/Accounting_information_system

    An accounting information system (AIS) is a system of collecting, storing and processing financial and accounting data that are used by decision makers. An accounting information system is generally a computer-based method for tracking accounting activity in conjunction with information technology resources. The resulting financial reports can ...

  8. sbrk - Wikipedia

    en.wikipedia.org/wiki/Sbrk

    brk and sbrk are basic memory management system calls used in Unix and Unix-like operating systems to control the amount of memory allocated to the heap segment of the process. [1] These functions are typically called from a higher-level memory management library function such as malloc.

  9. cgroups - Wikipedia

    en.wikipedia.org/wiki/Cgroups

    cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, etc. [1]) of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers". [ 2 ]
