Difference Between Keyword and Identifier
Every programming language has keywords and identifiers. Both keywords and identifiers can be processed by a compiler, however they are quite different from each other. The basic difference between the two is that keywords are the reserve words which are predefined and have a special meaning in the language, whereas an identifier is a unique name assigned to a variable, function, class, etc. Read this article to learn more about keywords and identifiers and how they are different from each other. What is a Keyword? Keywords are reserved words that have a special meaning in a programming language. Therefore, we ...
Read MoreDifference Between Identifier and Variable
An Identifier is a name assigned to an entity in a computer program so that it can be identified distinctly in the program during its execution. On the other hand, a variable is a name assigned to a memory location that stores a value. Read this article to learn more about identifiers and variables and how they are different from each other. What is an Identifier? Identifiers are used to name a variable, a function, a class, a structure, a union. In other words, an identifier is created to give a unique name to an entity. It can consist of ...
Read MoreDifference between Header file and Library
In C, C#, Java or any other programming language, both header files and libraries provide some specific APIs and their functionality to be used in the main file. Both the header file and the library are combined and used as a single unit. But, on the basis of nature of files, we can distinguish between a Header File and a Library. Read this tutorial to learn more about header files and libraries and how they are different from each other. What is a Header File? The file that contains all the header names which are to be used in the ...
Read MoreDifference between Graphics Card and Video Card
Graphics Card and Video Card are often used interchangeably, as they are technically the same. Both cards act as an expansion card to generate output images and to transmit them to a display device. They are also called Graphical Processing Unit (GPU). A GPU has its own memory and processing power to fulfill the high processing requirements of visual experience. Read this article to learn more about graphics cards and video cards and how they are different from each other. What is a Video Card? A Video Card is also called a video controller and appears as a circuit board ...
Read MoreDifference between Fuzzification and Defuzzification
Fuzzification is the process of converting a crisp quantity into a fuzzy quantity. On the other hand, defuzzification is the process of translating a fuzzy quantity into a crisp quantity. Read this article to learn more about fuzzification and defuzzification and how they are different from each other. What is Fuzzification? Fuzzification may be defined as the process of transforming a crisp set to a fuzzy set or a fuzzy set to fuzzier set. Basically, this operation translates accurate crisp input values into linguistic variables. In a number of engineering applications, it is necessary to defuzzify the result or rather "fuzzy ...
Read MoreDifference between Functional and Non-functional Testing
Testing is the most important stage in the process of delivery of any application or software, as it not only validates the quality of an application but also provides an opportunity to the developer to improve its product. Every application is developed as per the requirements of a customer/client. So, on the basis of testing the functionality of an application based on these requirements and testing the usability and performance, we can distinguish between Functional and Non-functional Testing. Read this article to learn more about functional and non-functional testing and how they are different from each other. What is Functional ...
Read MoreDifference between Forward Engineering and Reverse Engineering
Both Forward and Reverse Engineering are related to the re-implementation of the legacy systems to achieve more sustainability. On the basis of the mode of creation, we can classify these modes as Forward and Reverse Engineering. Read this article to learn more about forward engineering and reverse engineering and how these two approaches are different from each other. What is Forward Engineering? Forward Engineering is the mode of development of an application in which the development is done on the basis of given requirements from the client or consumer. In forward engineering, the requirements are provided before the development ...
Read MoreDifference between Deterministic and Non-deterministic Algorithms
In the context of programming, an Algorithm is a set of well-defined instructions in sequence to perform a particular task and achieve the desired output. Here we say "a set of defined instructions" which means that somewhere the user knows the outcome of those instructions if they get executed in the expected manner. On the basis of the knowledge about outcome of the instructions, there are two types of algorithms namely, Deterministic and Non-deterministic Algorithms. Read this article to learn more about deterministic and non-deterministic algorithms and how they are different from each other. What is Deterministic Algorithm? A deterministic ...
Read MoreDifference Between Descriptive and Predictive Data Mining
Descriptive data mining and predictive data mining are mining techniques that are used to find useful information and patterns in large datasets. Descriptive data mining is a data mining technique that analyzes the past data to provide latest information on past events, while predictive data mining is a data mining technique that is used to analyze past data and provides answers of future queries. Read this this article to learn more about descriptive and predictive data mining techniques and how they are different from each other. What is Descriptive Data Mining? Descriptive data mining is a data mining technique that ...
Read MoreDifference Between DELETE and DROP in SQL
DELETE is a Data Manipulation Language (DML) command. It is used to remove tuples/records from a relation/table. On the other hand, DROP is a Data Definition Language (DDL) command and is used to remove named elements of schema like relations/table, constraints or entire schema. Read this article to learn more about DELETE and DROP commands in SQL and how they are different from each other. What is DELETE in SQL? In SQL, the DELETE command is used to remove some or all the records from a database table. With the DELETE command, the WHERE clause is used to define the ...
