There are three stages in this process. These are: Qualification, Adaptation (also known as wrapping), Composition (all in the context of components).Component qualification: examines reusable components. These are identified by characteristics in their interfaces, i.e., the services provided, and the means by which consumers access these services. This does not always provide the whole picture of whether a component will fit the requirements and the architectural style. This is a process ...
Ques : Describe similarities and differences between Cleanroom and OO Paradigm
posted on , by Anonymous
Ans : The following are the similarities and the differences between the Cleanroom software engineering development and OO software engineering paradigm.Similarities Lifecycle - both rely on incremental development Usage - cleanroom usage model similar to OO use case State Machine Use - cleanroom state box and OO transition diagram Reuse - explicit objective in both process modelsKey Differences Cleanroom relies on decomposition and OO relies on composition Cleanroom relies ...
A formal method in software development is a method that provides a formal language for describing a software artifact (e.g., specifications, designs, source code) such that formal proofs are possible, in principle, about properties of the artifact so expresse ...
Mathematics supports abstraction and therefore is a powerful medium for modeling. Because they are exact, mathematical specifications are unambiguous and can be validated to uncover contradictions and incompleteness. It allows a developer to validate a specification for functionality. It is possible to demonstrate that a design matches a specification, and that some program code is a correct reflection of a design How is the mathematics of formal languages applied in software development? What ...

The OECD an international organization working in the area of data privacy and information security, established an ad hoc process of meetings (the first was on 1-2 July 1997 and second on 22 October 1997) on approaches being taken in major industrial countries for the regulation of content conduct on the Internet. The meeting acknowledged the primary role of the private sector in regulating the Internet. However, at the joint OECD/Business and Industry Advisory Committee forum held on 25 ...
• It is faster than stream cipher. • If any block contains any transmission error then it will not have affect on other blocks. • It is not sufficient in hardware but may be used to connect keyboard to CPU (central process unit)• Block ciphers can be easier to implement in software, because there is no bit manipulation like in stream cipher which is time consuming process and treats data in computer-sized blocks • Block Cipher is more suitable in trading applications. • Short blocks at the end ...
If you need to line up the cells next to each other you can resize and move the layout cells as you need. You can change the size of a layout cell by using one of its resize handles.You cannot click and drag a cell to move it to a new position. If you need to move a layout cell to reposition it in a document, follow these stepsClick the border of a layout cell to select it.To move the layout cell, do one of the following:1- Use the arrow keys.2- Hold down Shift and use the arrow keys to move ...

Besides three storage class specifications namely, Automatic, External and Static, there is a register storage class. Registers are special storage areas within a computer’s CPU. All the arithmetic and logical operations are carried out with these registers.For the same program, the execution time can be reduced if certain values can be stored in registers rather than memory. These programs are smaller in size (as few instructions are required) and few data transfers are required. The reduction ...
In case of single file programs static variables are defined within functions and individually have the same scope as automatic variables. But static variables retain their values throughout the execution of program within their previous values.Points to remember:• The specifier precedes the declaration. Static and the value cannot be accessed outside of their defining function.• The static variables may have same name as that of external variables but the local variables take precedence ...
