Testing and debugging processes in software development are used to improve the quality of the software product and make it error and fault free. The testing and debugging processes are differentiated by the fact that testing finds the software defects devoiding its correction. Conversely, debugging is a more profound process where the bugs are not only identified but segregated and fixed from the code. While performing testing, we can use any of its types like unit, integration, and system … [Read more...]

The COCOMO 1 and COCOMO 2 are the cost estimation models developed by Barry Boehm for computing the cost of the developing software. Initially, COCOMO basic model was introduced, followed by the enhanced versions of the COCOMO model. The main difference between these COCOMO models is that the COCOMO 1 is completely premised on the linear reuse formula and the hypothetical idea about the stable set of requirements. In contrast, the COCOMO 2 is founded on the non-linear reuse formula, and also … [Read more...]

The System and Integration testing are the types of testing or test levels required to perform to detect the defects before the launch or delivery of the software product. The system and integration testing are distinguished depending on the which part of the developed software or product the test has been performed. System testing tests the behaviour of the entire system as specified by the scope of a development product. On the contrary, the integration testing tests the interfaces exists or … [Read more...]

The knowledge can be expressed in the various forms to the inference engine in the computers to solve the problems in context of the rule. So, in this article, we are going to discuss the two representation of procedural knowledge and declarative knowledge. The prior difference between them is that the declarative representation just specifies the knowledge but not the mechanism to implement the knowledge. On the contrary, the procedural representation provides the control information along with … [Read more...]

Fuzzification and defuzzification are the fuzzy inferencing system steps where the fuzzification translates the precise quantity as a fuzzy quantity whereas defuzzification converts the fuzzy quantity into a crisp one. The techniques are very useful in the fuzzy inference process, where the mapping is developed from a given input to an output with the help of fuzzy logic. This mapping provides the base for making the decision and discovering patterns. The fuzzy inference process is consist of … [Read more...]

The Waterfall and Spiral models are the process models used for developing software in a well-defined, systematic and cost-effective way. The major difference between these software process models waterfall and the spiral is that the waterfall model is comprised of the separate and isolate phases of specification and development. On the other hand, in a spiral model the different specification, development and validation phases are interleaved. These process model are a crucial part of … [Read more...]

Cardinality and Modality are the two data modelling concepts used for understanding the information domain of the problem. For analysing the data objects, data attributes and relationships structures, the terms given above are very important. The major difference between cardinality and modality is that the cardinality is defined as the metric used to specify the number of occurrences of one object related to the number of occurrences of another object. On the contrary, modality signifies … [Read more...]

The Agile and Waterfall are the highly used SDLC (Software Development Life Cycle) models to develop software or web-based product. The process in an agile method involves iterations in which requirements are validated, designed and tested during the iterations. Conversely, in waterfall projects the requirements are fixed at the beginning then the other phases occur. With an agile method, the new requirements and changes can be implemented in the next iteration while this is not possible in the … [Read more...]

There are several types of file format exists in the computer world, among them, an archive file format used to store different types of files in a single container. ZIP and RAR are the archive format mainly differ in the way that ZIP is a standard file format which is enabled by any operating system, but the RAR format needs other supplementary tools for their processing. Content: ZIP Vs RAR Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

The main intent of the communication system is to transfer the messages from a sender to the receiver. In this process, the signal used to transmit the information should be accordant with the properties of the transmission channel. The information coding is used to transform the message into the signal, i.e., signal information encoding where the message is encoded into codes. The prior difference between the Huffman coding and Shannon fano coding is that the Huffman coding suggests a variable … [Read more...]
