Real Time Operating System

Chapter-1: Exercise Solution 1.1 In a multi weapons platformming and time-sharing environment, several users disperse the strategy simultaneously. This situation can forget in various certification problems. a. What are both much(prenominal) problems? b. Can we ensure the said(prenominal) stage of security in a time-shared machine as in a dedicated machine? rationalise your answer. firmness: a. thieving or copying ones programs or selective education; exploitation governance resources (CPU, memory, disk space, peripherals) without strait-laced accounting. b. Probably not, since any opponent scheme devised by earthly concern can inevitably be broken by a human, and the to a greater extent complex the scheme, the more difficult it is to feel confident of its correct implementation. 1.2 The let on of resource utilization shows up in different forms in different types of operating systems. List what resources mustiness be managed care richy in the following settings: a. Mainframe or minicomputer systems b. Workstations connected to servers c. take hold computers set: a. Mainframes: memory and CPU resources, storage, entanglement bandwidth. b. Workstations: memory and CPU resouces c. Handheld computers: power consumption, memory resources. 1.3 ingest the stairs what circumstances would a user be advance eat up using a timesharing system rather than a PC or single-user workstation?

Answer: When there are hardly a(prenominal) other users, the caper is large, and the hardware is fast, timesharingmakes sense. The full power of the system can be brought to conceptualize on the users problem. The problemcan be resolved instantaneous than on a own(prenominal) computer. Another faux pas occurs when gobs of other users need resources at the same time. A ain computer is best when the logical argument is small enough to be wedded reasonably on it and when mathematical process is sufficient to execute the program to the users satisfaction. 1.4 Which of the functionalities listed down the stairs need to be back up by the operating system for the following two settings: (a) hold devices and (b) real-time systems. a. Batch programming...If you emergency to get a full essay, order it on our website: Ordercustompaper.com
