MGMT SS STATS, an umbrella body that facilitates and serves various Social SecurityOrganizations/Departments within the Caribbean territories, stoodpoised to meet the needs of its stakeholders by launching an onlinedatabase at www.SSDCI.gov. The database will provide membersand the public access to the complete set of services that can (also)be initiated face-to-face, and it will provide managed, private, secure access to a repository ofpublic and/or personal information. Ideally, the database will have basic details of pensionplans recorded in the registry, member plan statistics, and cash inflows and outflows frompension funds.For example, insured persons accumulate contributions. Records for these persons will includeinformation on the insured persons able to acquire various benefits once work is interrupteddue to sickness, death, retirement, and maternity or employment injury. They will also includeinformation on pensions such as invalidity, disability, and survivors that stem from…

- Consider a system with three smoker processes and one agent process. Each smoker continuously rolls a cigarette and then smokes it. But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has paper, another has tobacco and the third has the matches. The agent has an infinite supply of all three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes and smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Given below is a solution to the Cigarette-Smokers Problem. Give initial conditions for the semaphores as well as plausible values for the variables i & j and r & s, such that the agent and smokers are synchronized. Write a couple of sentences on why these initial conditions are necessary and sufficient.
