In computing, a command is a directive to a computer program acting as an interpreter of some kind, in order to perform a specific task.
A command-line interface or command language interpreter (CLI), also known as command-line user interface, console user interface and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).
In computing, multitasking is the concurrent execution of multiple tasks (also known as processes) over a certain period of time.
In computing, a context switch is the process of storing the state of a process or of a thread, so that it can be restored and execution resumed from the same point later.
Cooperative multitasking, also known as non-preemptive multitasking, is a style of computer multitasking in which the operating system never initiates a context switch from a running process to another process.
Cisco Embedded Event Manager (EEM) is a feature included in Cisco's IOS operating system (and some other Cisco OSes such as IOS-XR, IOS-XE, and NX-OS) that allow programmability and automation capabilities inside the device.
English is a West Germanic language that was first spoken in early medieval England and is now a global lingua franca.
IBM Internet Security Systems, formerly Internet Security Systems, and often known simply as ISS or ISSX (after its former NASDAQ ticker symbol) is a security software provider founded in 1994.
Internet access is the ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices; and to access services such as email and the World Wide Web.
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP).
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.

Junos OS (more formally Juniper Network Operating System) is the FreeBSD-based operating system used in Juniper Networks hardware routers.
Linux is a family of free and open-source software operating systems built around the Linux kernel.
In computer science, a microkernel (also known as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS).
A monolithic kernel is an operating system architecture where the entire operating system is working in kernel space and is alone in supervisor mode.
The term network operating system is used to refer to two rather different concepts.
A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks.
Packet forwarding is the relaying of packets from one network segment to another by nodes in a computer network.
Packet switching is a method of grouping data which is transmitted over a digital network into packets which are made of a header and a payload.
Proprietary software is non-free computer software for which the software's publisher or another person retains intellectual property rights—usually copyright of the source code, but sometimes patent rights.
QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market.
