Both decoder and demultiplexer are types combinational logic circuits used for implementing different types of digital systems. However, the function of a decoder is completely different from that of a demultiplexer. A decoder is a combination logic circuit that decrypts an input data stream from one format to another, whereas ... Read More

Both data warehouses and data marts serve the same purpose; they are data repositories. However, we can differentiate a data warehouse from a data mart on the basis of the amount of data they can store. A data warehouse a large repository of data that is collected from different organizations, ... Read More

Computer programming entirely revolves around data. It is data over which all the business logic gets implemented and it’s the flow of data which comprises the functionality of an application or project. Hence, it becomes critical to organize and store the data for its optimized use and perform effective programming ... Read More

Big Data represents the vast amount of data that can be structured, semi−structured, and unstructured sets of data ranging in terms of terabytes. In contrast, Data Mining is the process of discovering meaningful new correlations, patterns, and trends by sifting through a large amount of data stored in repositories, using ... Read More

Data Hiding and Encapsulation are important concepts in object-oriented programming (OOP). Data hiding helps prevent the illegal or unauthorized access of members of a class, while encapsulation helps in the wrapping up of data members and methods inside a class. The most basic difference between data hiding and encapsulation is ... Read More

The most basic difference between cohesion and coupling is that coupling is the representation of relationships between modules which uses the concept of inter−module, while cohesion is the intramodule representation of the relationship between modules. Read this article to find out more about Cohesion and Coupling and how these two ... Read More

In data mining, there are two major predication problems, namely, classification and regression. The most basic difference between classification and regression is that classification algorithms are used to analyze discrete values, whereas regression algorithms analyze continuous real values. The output variable must be either continuous nature or real value. The ... Read More

In HTML, cellpadding and cellspacing are the two attributes used for formatting table cells. Both cellpadding and cellspacing are used to insert whitespaces in the table cells. The most basic difference between cellpadding and cellspacing is that the cellpadding is used to set the whitespace between cell edge and cell ... Read More

For understanding the information domain of a problem, there are two data modelling concepts, namely, cardinality and modality. Cardinality and modality are very important for analyzing the data objects, attributes, and relationship structures. The most basic difference between cardinality and modality is that the cardinality is a metric that specifies ... Read More

Buffering and caching, two important concepts in operating systems, are used to increase the data transmission and processing speed. The most basic difference between buffering and caching is that buffering is used to sync the speed of data transmission between sender and receive, while caching is used to increase the ... Read More
