Osy CP 3

The document discusses operating systems and provides details about real-time operating systems (RTOS). It defines an RTOS as an operating system intended for real-time applications that process data as it arrives without buffer delays. Processing in an RTOS must occur within specific time constraints measured in tenths of seconds or less or the system will fail. RTOS are either event-driven, switching between tasks based on priorities, or time-sharing, switching tasks based on clock interrupts.

Types of Operating System


Real Time OS & Distributed OS
A real-time operating system (RTOS) is an operating system (OS) intended to
serve real-time applications that process data as it comes in, typically without
buffer delays. Processing time requirements (including any OS delay) are
measured in tenths of seconds or shorter increments of time. A real-time
system is a time-bound system which has well-defined, fixed time constraints.
Processing must be done within the defined constraints or the system will fail.
They either are event-driven or time-sharing. Event-driven systems switch
between tasks based on their priorities, while time-sharing systems switch the
task based on clock interrupts.
