## Bresenham Circle Drawing Algorithm

The Bresenham circle drawing algorithm is a computer graphics algorithm used to draw circles in a 2D space. It is named after its inventor, Jack Bresenham, who also created the Bresenham line drawing algorithm. The algorithm works by incrementally plotting pixels on the circumference of a circle. It uses integer arithmetic and avoids using expensive …

## Mid Point Line Drawing Algorithm

A Midpoint line drawing algorithm is a computer graphics algorithm used to draw a straight line between two points in a 2D space. It is similar to the Bresenham algorithm in that it also uses incremental calculations to plot the pixels that make up the line. The algorithm works by determining a midpoint between the …

## Bresenham Line Drawing Algorithm

The Bresenham line drawing algorithm is a computer graphics algorithm used to draw a straight line between two points in a rectangular grid. It is named after its inventor, Jack Bresenham. The algorithm works by calculating the coordinates of the pixels that should be colored to approximate the line. It uses integer arithmetic and avoids …

## Vector vs Bitmap

Vector and bitmap are two different types of digital images used in computer graphics. The main difference between them is the way they represent and store image data. Vector graphics are composed of mathematical equations that describe the image’s shape, size, and color. These equations define the image as a series of lines, curves, and …

## CRT (Cathode Ray Tube) Display

CRT stands for Cathode Ray Tube. It is an electronic device used in older televisions and computer monitors to display images. A CRT is a vacuum tube that uses an electron gun to emit a stream of electrons that are then directed toward a phosphorescent screen, creating an image. The electron beam is directed to …

## Points and Lines

In computer graphics, a point is a single, isolated coordinate in two-dimensional or three-dimensional space. It is the most basic element of a digital image, represented by a single pixel on a screen. Points are typically represented by their X, Y, and Z coordinates in 3D space and are often used to represent vertices or …

## Frame Buffer and Video Controller

A frame buffer is a portion of memory in a computer or graphics device that stores the image or video data that will be displayed on a screen. The frame buffer holds the pixel values for each point on the screen and updates those values as the image or video changes. The video controller, also …

## DDA Line Drawing Algorithm

DDA (Digital Differential Analyzer) algorithm is a computer graphics algorithm used for drawing lines on a raster display. The algorithm is based on the mathematical concept of the slope of a line and uses a step-by-step approach to calculate the pixels needed to draw the line. The basic steps of the DDA line drawing algorithm …

## Random Scan Display and Raster Scan Display

Random Scan Display Random Scan Display is a type of display system used in computer graphics that draw images and graphics on the screen using an electron beam that moves directly to the points where the drawing is required. It is a vector-based display system that is designed to draw lines and curves with great …

## Computer Graphics

Computer graphics refers to the creation, manipulation, and rendering of visual content using digital technology. It encompasses a wide range of fields including 2D and 3D graphics, animation, video game design, visual effects, virtual reality, and augmented reality. In computer graphics, artists and designers use software tools to create and manipulate images and animations, often …

## DNS Functions Explained

DNS, or Domain Name System, is a hierarchical and distributed naming system that translates human-readable domain names into IP addresses used by computers to identify and communicate with each other on the internet. The DNS system performs several critical functions, including: Example: When you type a website address into your web browser, such as www.google.com, …

## The Structure of HTTP Response

The HTTP (Hypertext Transfer Protocol) response message is sent by the server to the client in response to an HTTP request. The HTTP response message consists of several parts, including: Status line This is the first line of the HTTP response message, and it specifies the HTTP version, status code, and reason phrase of the …

## The Structure of HTTP Request

The HTTP (Hypertext Transfer Protocol) request message is sent by the client to the server to request a resource or perform an action. The HTTP request message consists of several parts, including: Request line This is the first line of the HTTP request message, and it specifies the method, URL, and HTTP version of the …

## Working of Email

Email, short for electronic mail, is a digital communication method that allows users to send and receive messages over the internet. The process of sending and receiving emails involves several steps: Email can also include attachments, such as documents, images, and videos, which are sent along with the email message. Email attachments can be stored …

## Use of Protocol on the Internet

In the context of the internet, a protocol refers to a set of rules and standards that govern communication between devices and systems. Protocols are essential for enabling devices and systems to communicate and exchange information with each other in a standardized and predictable manner. Some of the key uses of protocols on the internet …

## Web Development Strategies

Web Server A web server is a software application that processes and responds to client requests over the internet using the HTTP (Hypertext Transfer Protocol) or HTTPS (HTTP Secure) protocol. The primary function of a web server is to deliver web pages and other content to clients, such as web browsers, on behalf of a …
