Operating Systems Assignment #5 Of Chapter 4 Eighth Edition of Operating System Concepts by Avi Silberschatz Peter Baer Galvin & Greg Gagne 2009 4.1 Provide two programming examples in which multithreading does not provide better performance than a single-threaded solution Answer: (1) Any kind of sequential program is not a good candidate to be threaded. An example of this is a program that calculates an individual tax return. (2) Another example is a "shell" program such as

approaches are used for costing products for the purpose of valuing inventories and cost of goods sold. One approach is called absorption costing. Absorption costing is generally used for external financial reports. The other approach called variable costing is preferred by some companies for internal decision making and must be used when an income statement is prepared in the contribution format. Ordinarily absorption costing and variable costing produce different figures for net income and the difference

LIFE CYCLE COSTING Life cycle costing (LCC) is the process of collecting‚ interpreting and analyzing data and using quantitative tools and techniques to predict the future resources that will be required in any life cycle of a system of interest. LCC can also be defined as a technique to establish the total cost of ownership. It is a structured approach addresses all the elements of this cost and can used to produce a spend profile of a product over its life span. The result of LCC usually
