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...]

WAV and MP3 are the file formats for storing digital audio. These can be differentiated by the fact that the MP3 is the lossy and compressed type of file where some amount of information from the original audio source is discarded. On the other hand, the WAV format is an uncompressed type of audio file. The size of the WAV file is very much higher than the MP3 file. Content: WAV and MP3 Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

We must have heard the terms JPEG and GIF with respect to file formats. JPEG and GIF are the file formats which provide standards compression techniques for storing photographic images and mainly differ in the representation and the storage of the images where the JPEG can support and display single full photographic image within a file while GIF is comprised of multiple images in a single file. JPEG images are opaque while GIF images are partially transparent. Content: JPEG Vs GIF … [Read more...]

The crucial difference between ERP and CRM is that the ERP systems do not directly communicate with the customers but CRM systems require direct interaction with the customers. However these systems functioning may correspond, but they work in the different domain. The ERP contains a vast amount of structured data which can be handled easily while CRM can hold unstructured text. A CRM software can be considered as the subsystem of ERP. Content: ERP Vs CRM Comparison Chart … [Read more...]

In Artificial intelligence, the purpose of the search is to find the path through a problem space. There are two ways to pursue such a search that are forward and backward reasoning. The significant difference between both of them is that forward reasoning starts with the initial data towards the goal. Conversely, backward reasoning works in opposite fashion where the purpose is to determine the initial facts and information with the help of the given results. Content: Forward Vs Backward … [Read more...]

Searching is a process of finding a sequence of steps needed to solve any problem. The prior difference between informed and uninformed search is that the informed search provides the guidance on where and how to find the solution. Conversely, the uninformed search gives no additional information about the problem except its specification. However, between both informed and uninformed search techniques, the informed search is more efficient and cost-effective. Content: Informed Search Vs … [Read more...]
