The provided text appears to be a transcript of a lecture or presentation on operating systems, specifically discussing process management, memory management, and other related topics.
The speaker discusses the different states of a process (new, ready, running, waiting, and terminated) and how they transition between these states. They also touch on the topic of scheduling and dispatching, including the use of a dispatcher to manage the transition of processes between states.
The lecture also mentions the concept of time-sharing and the use of a scheduler to allocate time slots to processes. The speaker also discusses the idea of "sharing time" and how it relates to process scheduling.
Throughout the transcript, the speaker appears to be using a combination of prepared notes and improvisation, with some sections sounding more rehearsed than others. There are also some apparent mistakes or corrections made during the presentation.
The lecture concludes with a discussion on the concept of a "Smart City" and how it relates to process management, although this section appears to be somewhat tangential to the rest of the presentation.
