splice () is a Linux -specific system call that moves data between a file descriptor and a pipe without a round trip to user space. The related system call vmsplice () moves or copies data between a pipe and user space. Ideally, splice and vmsplice work by remapping pages and do not actually copy any data, which may improve I/O performance.
Splice (system call), a system call used to transfer data on Linux. Delayed binding, also called TCP connection splicing, is a postponement of the connection between the client and the server in computer networking. An operation between two linked lists, in which all or part of one list is transferred to another in constant time by relinking.
GFS2. In computing, the Global File System 2 or GFS2 is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage, in contrast to distributed file systems which distribute data throughout the cluster. GFS2 can also be used as a local file system ...
The SCM executable, Services.exe, runs as a Windows console program and is launched by the Wininit process early during the system startup. [2] Its main function, SvcCtrlMain(), launches all the services configured for automatic startup. First an internal database of installed services is initialized by reading the following two registry keys:
Copy-on-write. Copy-on-write (COW), sometimes referred to as implicit sharing[1] or shadowing, [2] is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources [3] (most commonly memory pages, storage sectors, files, and data structures).
System call. A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
Armies A1 and A2 cannot see one another directly, so need to communicate by messengers, but their messengers may be captured by army B. In computing, the Two Generals' Problem is a thought experiment meant to illustrate the pitfalls and design challenges of attempting to coordinate an action by communicating over an unreliable link.
