Svchost.exe (Service Host, or SvcHost) is a system process that can host one or more Windows services in the Windows NT family of operating systems. [1] Svchost is essential in the implementation of shared service processes, where a number of services can share a process in order to reduce resource consumption.
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.
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 receive ...
In computer operating systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary storage [a] for use in main memory. [1] In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
In general, memory access management is a responsibility of the operating system kernel, in combination with hardware mechanisms that provide supporting functionalities, such as a memory management unit (MMU). If a process attempts to access a memory location outside its memory space, the MMU denies the request and signals the kernel to take ...
In many modern operating systems, processes can consist of many sub-processes. This introduces the concept of a thread . A thread may be viewed as a sub-process ; that is, a separate, independent sequence of execution within the code of one process.
The terms logical host or cluster logical host is used to describe the network address that is used to access services provided by the cluster. This logical host identity is not tied to a single cluster node. It is actually a network address/hostname that is linked with the service(s) provided by the cluster.
In computer programming, resource management refers to techniques for managing resources (components with limited availability).. Computer programs may manage their own resources [which?] by using features exposed by programming languages (Elder, Jackson & Liblit (2008) is a survey article contrasting different approaches), or may elect to manage them by a host – an operating system or ...
