In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here:
A bulletin board is a surface intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information. Bulletin boards are often made of a material such as cork to facilitate addition and removal of messages, as well as a writing surface such as blackboard or whiteboard. A bulletin board which combines a pinboard (corkboard) and writing surface is known as a combination bulletin board. Bulletin boards can also be entirely in the digital domain and placed on computer networks so people can leave and erase messages for other people to read and see, as in a bulletin board system.
A whiteboard is a glossy, usually white surface for making non-permanent markings. Whiteboards are analogous to blackboards, but with a smoother surface allowing for rapid marking and erasing of markings on their surface. The popularity of whiteboards increased rapidly in the mid-1990s and they have become a fixture in many offices, meeting rooms, school classrooms, public events and other work environments.
Commercial software, or seldom payware, is a computer software that is produced for sale or that serves commercial purposes. Commercial software can be proprietary software or free and open-source software.
Web conferencing is used as an umbrella term for various types of online conferencing and collaborative services including webinars, webcasts, and web meetings. Sometimes it may be used also in the more narrow sense of the peer-level web meeting context, in an attempt to disambiguate it from the other types known as collaborative sessions. The terminology related to these technologies is exact and agreed relying on the standards for web conferencing but specific organizations practices in usage exist to provide also term usage reference.
Microsoft NetMeeting is a discontinued VoIP and multi-point videoconferencing program offered by Microsoft. NetMeeting allows multiple clients to host and join a call that includes video and audio, text chat, application and desktop sharing, and file sharing. It was originally bundled with Internet Explorer 3 and then with Windows versions from Windows 95 to Windows Server 2003.
An interactive whiteboard (IWB), also known as interactive board, interactive display, interactive digital board or smart board, is a large interactive display board in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector. They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others.
Software as a service is a form of cloud computing in which the provider offers the use of application software to a client and manages all the physical and software resources used by the application. The distinguishing feature of SaaS compared to other software delivery models is that it separates "the possession and ownership of software from its use". SaaS began around the turn of the twenty-first century and became the main form of software application deployment by 2023.
Adobe Connect is a software suite for remote training, web conferencing, presentation, and desktop sharing. All meeting rooms are organized into 'pods'; with each pod performing a specific role. Adobe Connect was formerly part of the Adobe Acrobat family and has changed names several times.
Skype for Business is an enterprise software application for instant messaging and videotelephony developed by Microsoft as part of the Microsoft 365 suite. It is designed for use with the on-premises Skype for Business Server software, and a software as a service version offered as part of 365. It supports text, audio, and video chat, and integrates with Microsoft 365 components such as Exchange and SharePoint.
BarCamp is an international network of user-generated conferences primarily focused on technology and the web. They are open, participatory workshop-events, the content of which is provided by participants. The first BarCamps focused on early stage web applications, and were related to open-source technologies, social software, and open data formats.
Application virtualization is a software technology that encapsulates computer programs from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, although it is still executed as if it were. The application behaves at runtime like it is directly interfacing with the original operating system and all the resources managed by it, but can be isolated or sandboxed to varying degrees.
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization emulates the hardware environment of its host architecture, allowing multiple OSes to run unmodified and in isolation. At its origins, the software that controlled virtualization was called a "control program", but the terms "hypervisor" or "virtual machine monitor" became preferred over time.
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions.
This list is a comparison of web conferencing software available for Linux, macOS, and Windows platforms. Many of the applications support the use of videoconferencing.
Proprietary software is software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms.
ShowDocument is an online web application that allows multiple users to conduct web meetings, upload, share and review documents from remote locations. The service was developed by the HBR Labs company, established in 2007.
Lucidchart is a web-based diagramming application that allows users to visually collaborate on drawing, revising and sharing charts and diagrams, and improve processes, systems, and organizational structures. It is produced by Lucid Software Inc., based in Utah, United States and co-founded by Ben Dilts and Karl Sun.
Freeform is a digital whiteboarding application developed by Apple for macOS, iOS, iPadOS, and visionOS devices, first revealed during the 2022 Worldwide Developers Conference, and officially launched on December 13, 2022, alongside iOS 16.2, iPadOS 16.2, and macOS 13.1. It allows users to create infinitely scaling canvases called "boards", which can display a range of inputs including text notes, photos, documents, and web links. There are also a variety of pen and brush tools available on the iOS and iPadOS versions of the software, letting users add sketches or handwriting to their boards similar to the tools available in the Notes app, which are compatible with the Apple Pencil.
