The realm of computer graphics is an expansive one that is always undergoing development. It involves a variety of concepts and ideas, of which "drawing a line" is the most fundamental tasks involved in working with graphical media.There are two algorithmic rules that are followed while drawing a line on the screen. They are DDA (Digital Differential Analyser) algorithmic rule and Bresenham line algorithm.Both the DDA and Bresenham's algorithm are examples of computational procedures that can be utilised for the goal of approximating the length of a line segment.What is DDA?The primary purpose of a DDA in computer graphics is ...

Both SQL and NoSQL Databases have their set of advantages and disadvantages. SQL databases can be considered when you are looking for data consistency, reliability, integrity, and when the data is structured. NoSQL databases are a much better option if the data is large, semi-structured, or unstructured and you are looking for faster storage and retrieval of data.With so many databases available in the market, it can get a little challenging for an enterprise to decide whether they should choose an SQL Database or a NoSQL Database. This article will show you the key differences between the two types of ... Read More
The demand for different programming languages is constantly shifting due to the creation of new mobile and online applications. Additionally, emerging programming languages provide useful capabilities for the construction of powerful websites. A study done by developers at 2020 shows that JavaScript is widely considered to be one of the most popular technologies.Both NodeJS and AngularJS are open-source technologies that are based on JavaScript and are in wide use. AngularJS is a framework written in JavaScript, while NodeJS is a runtime environment that works across several platforms.Angular is a client-side JavaScript framework that allows developers to construct dynamic web applications ...

In computer programming, the concept of reusable code refers to the utilisation of previously developed software in the construction of new software. Reusability of code is recognised as an essential component of productive functionality. Establishing associations between classes is one method that object-oriented programming uses to encourage this.In object-oriented programming, there are two primary ways to construct these relationships: inheritance and composition.In object-oriented programming (OOP), inheritance refers to the process through which an object can take on the properties of one or more other objects. In OOP, it is one of the most powerful concepts for establishing code reusability. When ... Read More
Hive and HBase are Hadoop-based Big Data solutions. These technologies serve different purposes in almost any real use scenario. When you log onto Facebook, you may see your friend's list, a news feed, ad suggestions, friend suggestions, etc. Twitter is similar.Apache Hadoop, along with other technologies we'll explore today, such as Apache Hive vs. Apache HBase, is how Facebook loads all of its messy data in a presentable manner. Apache Hadoop enables Facebook's two billion-plus daily users.Because Big Data systems are complicated, all technologies must be used together. Hive is recommended for analyzing time-series data. It can evaluate trends and ... Read More
Classes are the fundamental building blocks of Java. It is a programmable template that can be expanded upon, and it determines the form and characteristics of an item. One may say that a class is the most fundamental component of an object oriented programming language like Java. Each and every idea that will be put into action by means of a Java application must first be encased inside of a class. In object-oriented programming, the fundamental building blocks are called classes objects.Variables and methods are the building blocks of a Java class. Instance variables are the terms used to refer ... Read More
When a user presses the power button on their computer, it initiates the process known as "booting, " which loads and starts the operating system. Booting can also be thought of as a series of actions where the ROM of the computer is accessed in order to load the startup instructions. After that, the operating system is loaded from the disc that is now being used to boot the computer.A primary option for the boot disc is frequently the local hard drive. The process of booting the computer is finished when the operating system is loaded; at this point, the ... Read More
This tutorial will discuss how to write a Swift program to find the perimeter of the circle.Perimeter of the circle is also known as the circumference of the circle. It is used to calculate the boundary of the circle. Suppose we want to fence our circular garden so with the help of perimeter we can calculate the total amount of fence required to cover the boundary of the garden. We can calculate the perimeter of the circle with the help of the radius or diameter, here, Radius − It is known as the distance from the center to a point ... Read More
This tutorial will discuss how to write a swift program to multiply two floating point numbers.Floating point numbers are the numbers with fraction or numbers with decimal value for example 34.56, 987.23, 0.234, etc. In Swift, floating point data type has a wide range of values and can store much smaller or larger number as compare to Integer. Swift support two signed floating point number types that is Double and Float. Double is used to represent 64-bit floating point number and has precision of at least 15-decimal digit. Whereas Float is used to represent 32-bit floating point number and has ... Read More
This tutorial will discuss how to write a swift program to print an Integer. Integers represents the number with no fractional component like 45, 980, -234, 24, etc. Swift supports both signed as well as unsigned integers in 8, 16, 32, and 64 bit. Here signed integer is represented by Int whereas unsigned integer is represented by UInt and their size is same as the current platform e.g if the platform is 32-bit then the size is Int32 or UInt32 unless you work with some specific size of the integer.SyntaxFollowing is the syntax for creating integer type variablevar x : ...
