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.
Windows Management Instrumentation. Windows Management Instrumentation (WMI) consists of a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components provide information and notification. WMI is Microsoft 's implementation of the Web-Based Enterprise Management (WBEM) and ...
Computer telephony integration. Computer telephony integration, also called computer–telephone integration or CTI, is a common name for any technology that allows interactions on a telephone and a computer to be coordinated. The term is predominantly used to describe desktop -based interaction for helping users be more efficient, though it ...
Interface (computing) In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. [1] Some computer hardware devices, such as a touchscreen, can both send and ...
Library (computing) In computer science, a library is a collection of read-only resources that is leveraged during software development to implement a computer program. Historically, a library consisted of subroutines (generally called functions today). The concept now includes other forms of executable code including classes and non-executable ...
The Message Passing Interface (MPI) is a standardized and portable message-passing standard designed to function on parallel computing architectures. [1] The MPI standard defines the syntax and semantics of library routines that are useful to a wide range of users writing portable message-passing programs in C , C++ , and Fortran .
exec (system call) In computing, exec is a functionality of an operating system that runs an executable file in the context of an already existing process, replacing the previous executable. This act is also referred to as an overlay. It is especially important in Unix-like systems, although it also exists elsewhere.
write (system call) The write is one of the most basic routines provided by a Unix-like operating system kernel. It writes data from a buffer declared by the user to a given device, such as a file. This is the primary way to output data from a program by directly using a system call. The destination is identified by a numeric code.
