Workspace refers to small premises provided, often by local authorities or economic development agencies, to help new businesses to establish themselves. These typically provide not only physical space and utilities, but also administrative services and links to support and finance organisations, as well as peer support among the tenants. A continuum of sophistication ranges through categories such as 'managed workspaces', 'business incubators' and 'business and employment co-operatives'. In cities, they are often set up in buildings that are disused but which the local authority wishes to retain as a landmark, such as tramsheds. At the larger end of the spectrum are business parks, technology parks and science parks.

A workspace is (often) a file or directory that allows a user to gather various source code files and resources and work with them as a cohesive unit. Workspaces are very helpful in cases of complex projects when maintenance can be challenging. A good example of an environment that allows users to create and use workspaces is Microsoft Visual Studio.
From the view of configuration management, a workspace is a part of the file system where the files of interest (for a given task like debugging, development, etc.) are located. A workspace acts as an environment where a programmer can work, isolated from the outside world, for the task duration.
Multiple workspaces are prevalent on Unix-like operating systems and certain operating system shells. Mac OS X 10.5 includes an equivalent feature called "Spaces"; a Windows XP PowerToy is available to bring this functionality to Windows.
Most systems with support for workspaces provide keyboard shortcuts to switch between them. Many also include some form of workspace switcher to change between them and sometimes to move windows between them as well.
Workspaces are visualized in different ways. For example, on Linux computers using Compiz or Beryl with the Cube and Rotate Cube plugins enabled, each workspace is rendered as a face of an on-screen cube, and switching between workspaces is visualized by zooming out from the current face, rotating the cube to the new face, and zooming back in. On Mac OS, the old set of windows slides off the screen and the new set slides on. Systems without "eye candy" often simply remove the old windows and display the new ones without any sort of intermediate effect.
Such applications have several advantages over traditional  clients or virtual folder offerings, including:
Beyond organizing and sharing files, these applications can often also be used as a business communication tool for assigning tasks, scheduling meetings, and maintaining contact information.
