Computer Graphics and It's Types

What is Computer Graphics?

Computer Graphic is an art of drawing pictures on computer screens with the help of programming . It involves computation, creation and manipulation of data. 

In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images.

Computer graphics is  a field related to the generation of graphics using computers.

In short, it refers different things:-

  • Pictures, scenes that are generated by a computer.
  • Tools used to make such pictures, software and hardware, input/output devices.
  • The whole field of study that involves these tools and the pictures they produce.

Types of Computer Graphics

Basically, there are two types of computer graphics namely.

  1. Interactive Computer Graphics 
  2. Non -interactive Computer Graphics

 1. Interactive Computer Graphics 

  • Interactive computer graphics refers to the field of computer graphics that focuses on creating graphical content that users can interact with in real-time. 
  • Interactive computer graphics is used in a wide range of applications including video games, simulations, virtual reality environments, scientific visualization, architectural design, and more.
    Key components of interactive CG:-

  • Rendering: The process of generating images from geometric models and textures. 
  • User Interaction: Enabling users to manipulate graphical elements or navigate within a virtual environment using input devices. 
  • Real-time Performance: Ensuring that the graphical system can update and render images at a rate that provides a smooth and responsive user experience.
  • Animation: Creating dynamic motion or changes in the graphical scene over time.

2. Non-interactive Computer Graphic

  • The non-interactive compute graphics is also known as passive computer graphics. It is the computer graphics in which user does not have any kind of control over the image.
  • The image is totally under the control of program instruction not under the user. 
          Example: Screen savers.

Error Detection And Correction Codes (Digital Logic)

Basic approach used for error detection is the use of redundancy, where additional bits are added to facilitate detection and correction of errors.  Popular technique are:  Simply Parity Check Two-dimension parity check Checksum Cyclic redundancy check Parity method for Error Detection Table: Message with even parity and odd parity Even Parity  Definition: In even parity the number of bits set to 1 in a data item, including the parity bit itself is always even. If the number of 1s in the data is odd, the parity bit is set to 1 to make the total number of 1s even. Odd Parity Definition: In odd parity the number of bits set to 1 in the data item including the parity bit is always odd. If the number of 1s in the data is even the parity bit is set to 1 to make the total number of 1s odd. Notes: - Parity method is only for the error detection not for the error correction. -  This method provide for the detection of single bit error (or any odd number of errors, which is...

Operating System        What is Operating System ? Overview An operating system (OS) is a software program that acts as an intermediary between computer hardware and the applications that run on a computer. It manages and coordinates various hardware and software components to provide a user-friendly and efficient environment for computing.  Key functions of an operating system includes: Process Management: The OS handles the execution of processes (programs) by allocating CPU time, managing process synchronization, and controlling process communication. Memory Management: It manages the computer's memory, allocating and deallocating memory space for different programs and ensuring efficient utilization of available memory resources. File System Management: The OS manages files and directories on storage devices, facilitating reading, writing, and organization of data on storage media such as hard drives, solid-state drives, and removable devices.
