Expert Solution & Answer
Chapter 18, Problem 50E
Explanation of Solution
AT&T failure:
- In January 1990, AT&T’s long-distance network was halted for nine hours, because of the software error in the switching systems.
- This causes losses in the revenue generation in hotels, rental car agencies, and telemarketing companies.
- But the earlier versions of the switching software worked correctly.
- While upgrading the system to provide a quick response, a software error occurred on a month later due to missing of the break statement in the “C-code”...

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…

The Test-and-Set instruction is used in hardware to achieve synchronization. It can be defined in the following way: function Test-and-Set (var target: boolean): boolean; begin Test-and-Set:= target; target := true; end; Now show how the Test-and-Set instruction can be used to protect a critical region and hence achieve mutual exclusion (do not worry about satisfying the bounded waiting condition).

- 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.
