Intro to Operating Systems Student Gabriel Guevara Chapter 5 physical exercises Exercise 2 Give at least(prenominal) two real life pillow slips (not related to a data processor system environment) of apiece of these concepts cul, starvation and race. Describe how the deadlocks could be re pull ind. 2 real life examples of the concept of deadlock A. In a presidential election 2 expectations reach an electoral deadlock when neither candidate get a majority of the 270 electoral votes required to win the presidency.This is resolved by the House of Representatives, with each state delegation having one vote. Senators would elect the vice-president. B. Diet deadlock occurs when calories are restricted when a piece being is dieting , as a consequence the bodys metabolism slows down The motive is the body is worried about going into starvation mode and is trying to holdown to leftover body fat. The firmness to diet deadlock is to 1. Eat more protein to boost metabolism. 2. Lift we ights to increase brawn mass, the more muscle mass the more calories burned in a 24 hour period (day). . Do more cardio to burn more calories. 2 Real life examples of Starvation Hypoxia is the name given to oxygen starvation, for example of this human body is when brain tissue is deprived of oxygen-rich-blood, if this condition lingers a range of events could follow such as permanent brain damage or death. The solution is to restore the flow of oxygen-rich-blood to the brain via any functional procedure that would unlock the deadlock or flow of vital oxygen enriched blood back into the brain.Aviation give the axe starvation occurs when there is a supply problem to the engine for various reasons such as a blocked elicit filter or gradual fuel pump failure. But the most habitual problem with fuel starvation is with aircraft with water contaminated fuel being delivered to the engine instead of none-contaminated fuel resulting in fuel starvation within the engine. This is correcte d by replacing the fuel filter or fuel pump and testing the fuel for the presence of water prior to use for a flight. 2 Examples of the term race Exploitative competition is when 2 organisms vie for the same(p) resources.One way for nature to solve this condition is to naturally develop habitat conditions to induce mutualistic bonds between the 2 organisms so that one cannot get going in their natural habitat without the other, therefore perhaps reversing deadlock conditions. Organism competition Utilization of the same resources by organisms of the same or different species living together in a community resulting in a sort of deadlock competition for said resources. One way to relief this deadlock condition is for one organism to develop a method of eliminating the other by intelligently depriving it from the resource in question.Advance exercise 14 A system that is in an dangerous state is not necessarily deadlock. inform why this is true? Give an example of such system (in an unsafe state) and describe how all the processes could be completed without causing deadlock to occur. Answer 1 An unsafe state doesnt suggest a realistic deadlock is presently occurring it appears this term is used to described that a sequence of events have at a succession set favorable condition(s) to suggest a deadlock is highly likely to occur.Answer 2 An example of an unsafe state within a system could be where a system has jobs in its request queue up greater than what is available in memory to handle the jobs waiting to be executed, setting ideal conditions for a deadlock. The concept of avoidance suggest that the system can remove one of the deadlock conditions if it knew ahead of time the sequence of a request associated with each of the active processes. There must exist at least one allocation of resources sequence that would allow jobs to continue without becoming deadlocked.
