{{History of computing}}
In [[computing]], '''time-sharing''' is the [[Concurrency (computer science)|concurrent]] sharing of a computing resource among many tasks or users by giving each [[Process (computing)|task]] or [[User (computing)|user]] a small slice of [[CPU time|processing time]]. This quick switch between tasks or users gives the illusion of [[Parallel computing|simultaneous]] execution.<ref>{{Cite web |date=2023-11-23 |title=Time-sharing definition – Glossary {{!}} NordVPN |url=https://nordvpn.com/pt/cybersecurity/glossary/time-sharing/ |access-date=2024-06-17 |website=nordvpn.com |language=pt}}</ref><ref>{{Cite web |date=2020-04-28 |title=Time Sharing Operating System |url=https://www.geeksforgeeks.org/time-sharing-operating-system/ |access-date=2024-06-17 |website=GeeksforGeeks |language=en-US}}</ref> It enables [[computer multitasking|multi-tasking]] by a single user or enables multiple-user sessions.

Developed during the 1960s, its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact [[concurrent computing|concurrently]] with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one,<ref>IBM advertised, early 1960s, with a headline: "This man is sharing a $2 million computer"</ref> and promoted the [[Interactive computing|interactive use of computers]] and the development of new interactive [[application software|application]]s.
