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.
Mobile appA mobile app or application is a computer program or software application designed to run on a mobile device such as a smartphone, tablet, or smartwatch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device.
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.
Utility softwareUtility software is software that supports managing the computerinfrastructure including computer hardware, system software and application software. Utility software provides for performing tasks as a system administrator (that is, as a user acting in that role). In contrast, application software provides for performing tasks as an end user. A utility may be a distinct program, or multiple utilities are implemented in a single program.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.
App Store (Apple)Mobile app distribution platform by AppleThe App Store is an app marketplace developed and maintained by Apple, for mobile apps and desktop apps on its iOS, macOS and iPadOS operating systems. The store allows users to browse and download approved apps developed within Apple's iOS SDK. Apps can be downloaded on the iPhone, iPod Touch, or iPad, and some can be transferred to the Apple Watchsmartwatch or 4th-generation or newer Apple TVs as extensions of iPhone apps.

Computer operatorA computer operator is a role in IT which oversees the running of computer systems, ensuring that the machines, and computers are running properly. The job of a computer operator as defined by the United StatesBureau of Labor Statistics is to "monitor and control ... and respond to ... enter commands ... set controls on computer and peripheral devices. This Excludes Data Entry." OverviewThe position has evolved from its beginnings in the punched card era.
Computer programmingComputer programming is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit.
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.AbbreviationAn abbreviation (from Latin brevis 'short') is a shortened form of a word or phrase, by any method including shortening, contraction, initialism (which includes acronym), or crasis. An abbreviation may be a shortened form of a word, usually ended with a trailing full stop (period). For example, the term etc. is the usual abbreviation for the Latin phrase et cetera.
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.*As an Amazon Associate I earn from qualifying purchases.
