In 2001, Thinsoft BeTwin offered a multiseat solution for Windows, utilizing multiple graphics cards and peripherals attached to a single host PC. [2] In 2002 a Canadian company, Userful Corporation, released Userful Multiplier, a multiseat Linux software solution that enables up to 10 users to simultaneously share one computer. [3]
Some multi-user operating systems such as Windows versions from the Windows NT family support simultaneous access by multiple users (for example, via Remote Desktop Connection) as well as the ability for a user to disconnect from a local session while leaving processes running (doing work on their behalf) while another user logs into and uses ...
In Windows Vista, GINA is replaced by Credential Providers; however, they do not support programmatic initiation of fast user switching. [6] In Windows XP, fast user switching was unavailable if the computer is on a Windows Server domain network or if Offline Files was enabled. Windows Vista and later no longer have these restrictions. [7]
Windows MultiPoint Server is an operating system based on Microsoft Windows Server using Remote Desktop Services technology to host multiple simultaneous independent computing stations or terminals connected to a single computer (multiseat computing).
As system performance may degrade due to the complexity of processing multiple jobs from multiple users at the same time, the capacity of such a system may be measured in terms of maximum concurrent users. [2] [3] Second, commercial software vendors often license a software product by means of a concurrent users restriction. This allows a fixed ...
In computing, time-sharing is the concurrent sharing of a computing resource among many tasks or users by giving each task or user a small slice of processing time. This quick switch between tasks or users gives the illusion of simultaneous execution. [1] [2] It enables multi-tasking by a single user or enables multiple-user sessions.
A processor intended for use with multitasking operating systems may include special hardware to securely support multiple tasks, such as memory protection, and protection rings that ensure the supervisory software cannot be damaged or subverted by user-mode program errors.
In this way, multiple processes are part-way through execution at a single instant, but only one process is being executed at that instant. [ citation needed ] Concurrent computations may be executed in parallel, [ 3 ] [ 6 ] for example, by assigning each process to a separate processor or processor core, or distributing a computation across a ...
