If the critical task is not completed within the time constraint, then the system fails. this system has to complete all the processes within the definite deadline and a single miss leads to critical failure. e.g.: pace maker, flight control system( any miss in deadline leads to crash).

Os Notes Unit 1 Pdf Thread Computing Process Computing Complete operating system notes for placements and gate exam. An operating system (os) is an interface between a computer user and computer hardware. an operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. The os continuously checks for the possible errors. the os takes an appropriate action to correct errors and consistent computing. Monolithic structure: all os components are tightly integrated (e.g., early unix). layered structure: os is divided into layers; higher layers use services of lower ones. microkernel: only essential services (memory, process scheduling) in kernel. modular: uses loadable modules (e.g., linux). For each type of error, os should take the appropriate action to ensure correct and consistent computing. debugging facilities can greatly enhance the user’s and programmer’s abilities to efficiently use the system. another set of os functions exists for ensuring the efficient operation of the system itself via resource sharing.
