Software and Applications
Software and applications (often referred to simply as “apps”) are crucial for performing various tasks on computers and mobile devices. Here are some key terms to know.
Operating System (OS): The software that supports a computer’s basic functions, such as scheduling tasks, executing applications, and controlling peripherals. Common operating systems include Windows, macOS, Linux, iOS, and Android.
Application (App): A software program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples include web browsers, games, and productivity tools.
Cloud Computing: The delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”). Cloud computing allows users to access and store data remotely rather than on local devices.
SaaS (Software as a Service): A software distribution model in which applications are hosted by a service provider and made available to customers over the internet. Examples of SaaS include Google Workspace, Salesforce, and Dropbox.
API (Application Programming Interface): A set of rules and protocols for building and interacting with software applications. APIs allow different software systems to communicate with each other.
Open Source: Software for which the original source code is made freely available and may be redistributed and modified. Examples of open-source software include the Linux operating system, the Apache HTTP Server, and the Mozilla Firefox web browser.
Emerging Technologies
Technology is always evolving, and new innovations are continually emerging. Here are some terms related to the latest advancements in technology.
