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...]
Difference Between System Testing and Integration Testing
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...]
Difference Between PHP and JavaScript
The PHP and JavaScript are programming languages intended for the different purposes where the PHP is mostly used for the backend purpose. On the contrary, JavaScript is used for frontend. In other words, PHP is a server-side scripting language whereas JavaScript is considered as a client-side scripting language. The features provided by PHP are more but the JavaScript is said to be more efficient and fast. PHP provides a wide of variety of functions as compared to JavaScript. Content: PHP … [Read more...]
Difference Between For and Foreach in PHP
In PHP there are four types of loops in general, while, do while, for and foreach. In this article, we are going to examine the differences between for and foreach, where the prior difference between them is that for loop uses iterator variable while foreach works only on interator array. Looping in a programming language play a crucial role in any programming construct. The primary function of a loop is to execute the same block of code several times, repeatedly until a certain condition is … [Read more...]
Difference Between Procedural and Non-procedural Language
With advances in various disciplines of science and engineering the requirement of the more advanced computational models for solving a problem that need large computational and storage environments. Procedural and nonprocedural languages are the computations models for specifying most programming today. The major difference between these computational models is that the procedural language is command-driven whereas non-procedural language is function oriented. Furthermore, procedural … [Read more...]
Difference Between Azure and AWS
We are aware of cloud computing, and the services that the cloud provides, and if you have no idea about it, you may refer previous articles provided in the website to understand it better. In this article, we will be discussing the two types of cloud services, Azure and AWS. The significant difference between Azure and AWS is that the Azure is a Microsoft based cloud service while AWS stands for Amazon Web Services; hence, it is Amazon based service. The computing resources that the AWS uses … [Read more...]
Difference Between Top-down and Bottom-up Parsing
The major difference between types of parsing techniques top-down and bottom-up parsing is that the top-down parsing follows method to construct a parse tree for an input string which begins at the root and grow towards the leaves. As against, in bottom-up parsing, a reverse method where the parsing starts from the leaves and directed towards the leaves. Before understanding the types of parsing, we must know what is parsing and why it's done. Parsing is the technique of examining a text … [Read more...]
Difference Between Procedural and Declarative Knowledge
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...]
Difference Between Fuzzification and Defuzzification
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...]
Difference Between Waterfall Model and Spiral Model
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...]
