System softwareSystem software is software that provides a platform for other software. Examples include the kernel and device drivers of an operating system (OS). A program that runs in the context of the platform is classified as application or utility software based on the functionality it provides and the role of intended users. Application software provides for the normal use of a computer, without regard to how the computer works or what it needs to function.Application softwareApplication software is software that is intended for end-user use – not operating, administering or programming a computer. It includes programs such as word processors, web browsers, media players, and mobile applications used in daily tasks. An application (app, application program, software application) is any program that can be categorized as application software.
Command-line interfaceA command-line interface (CLI), also known as a command-line shell, is a means of interacting with software via commands – each formatted as a line of text. The concept of interacting with a computer via text evolved over two decades, transitioning from physical hardware to sophisticated software. Before the CLI, computers were programmed using physical switches or punched cards. The shift toward a "command" style interaction began with the use of Teleprinters (Teletypes).
System administratorAn IT administrator, system administrator, sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as servers. The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so.
Computer programInstructions a computer can executeSource code for a computer program written in the JavaScript language. It demonstrates the appendChild() method. The method adds a new child node to an existing parent node. It is commonly used to dynamically modify the structure of an HTML document.A computer program is a sequence or set of instructions in a programming language for a computer to execute.
Computer hardwareComputer hardware, commonly shortened to hardware, includes the physical parts of a computer, such as the central processing unit (CPU), random-access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. By contrast, software is a set of written instructions that can be stored and run by hardware.SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.

End userIn product development, an end user is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, information technology (IT) experts, software professionals, and computer technicians.
InfrastructureInfrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access).
User (computing)A user is a person who uses a computer or networkservice. A user typically has a user account and is recognized by the system through a username. Some software products provide services to other systems and have no direct end users. End userEnd users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians.*As an Amazon Associate I earn from qualifying purchases.
