William Fetter, a graphic designer for Boeing, coined the term ‘Computer Graphics’ in 1960 to describe his work.
Q.2 The component of interactive computer graphics are?
A light pen
Display unit
mouse
All of these
Explanation
Interactive computer graphics require hardware components like input devices (mouse, light pen) and output devices (display unit) to function.
Q.3 Which devices provide positional information to the graphic system?
Input device
Output device
Pointing device
Both (a) and (b)
Explanation
Input devices, specifically pointing devices like a mouse or stylus, are used to provide coordinate or positional data to the system.
Q.4 In graphic system, the array of pixels in the picture is stored in:
Memory
Frame buffer
Processor
All of the mentioned
Explanation
The frame buffer is a specialized region of memory that stores the color intensity values for every pixel on the screen.
Q.5 Types of computer graphics are?
Vector and raster
Scalar and raster
Vector and scalar
All of the mentioned
Explanation
The two fundamental types of computer graphics are Raster (pixel-based) and Vector (mathematical path-based).
Q.6 The smallest unit of picture?
Image
Pixels
Animation
All of the mentioned
Explanation
A pixel (picture element) is the smallest physical point in a raster image or the smallest addressable element on a display device.
Q.7 Pixel stands for?
Picture Electron
Picture Element
Picture Icon
None of these
Explanation
The word ‘pixel’ is derived from a combination of ‘pix’ (pictures) and ‘el’ (element).
Q.8 The maximum number of points that can be displayed without overlap on a CRT is referred as:
Picture
Resolution
Persistence
Neither (b) and (c)
Explanation
Resolution defines the maximum number of distinct pixels that can be displayed in each dimension on a screen.
Q.9 In LCD, the refresh rate of the screen is:
60 frames/ sec
80 frames/ sec
30 frames/ sec
100 frames/ sec
Explanation
Most standard LCD monitors operate at a default refresh rate of 60Hz (60 frames per second).
Q.10 Vector graphics is composed of?
Pixels
Paths
Palette
None of these
Explanation
Vector graphics use mathematical equations to define paths, lines, and curves rather than using a static grid of pixels.
Q.11 Raster graphics are composed of?
Pixels
Paths
Palette
None of these
Explanation
Raster images are made up of a rectangular grid of pixels, where each pixel is assigned a specific color value.
Q.12 The graphics can be?
Drawing
Photograph, movies
Simulation
All of these
Explanation
Computer graphics is a broad field that encompasses drawings, photography, cinematography, and real-time simulations.
Q.13 The primary output device in a graphic system is:
Scanner
Video monitor
Neither (a) and (b)
Printer
Explanation
The video monitor is the most common and essential output device used to visualize computer-generated graphics.
Q.14 The display device which also called as gas discharge display?
Plasma Panel
LED
LCD
None of these
Explanation
Plasma displays utilize small cells containing electrically charged ionized gases, which is why they are known as gas-discharge displays.
Q.15 Graphics system is a mediator between—- and ——- ?
Application program and hardware
System program and software
Application program and software
System program and Hardware
Explanation
The graphics system (software and drivers) acts as an interface that translates high-level application instructions into signals the hardware can execute.
Q.16 Aspect ratio means:
Number of pixels
Ratio of vertical points to horizontal points
Ration of horizontal points to vertical points
Both (b) and (c)
Explanation
Aspect ratio describes the proportional relationship between the width and height of an image or display.
Q.17 What is the name of the space in which the image is displayed?
World co-ordinate system
Screen co-ordinate system
World window
Interface window
Explanation
The screen coordinate system is the final 2D coordinate space where the pixels are mapped for the viewer to see.
Q.18 Raster Images Are More Commonly Called?
Pix Map
Bitmap
Both A & B
None of these
Explanation
Raster images are most frequently referred to as bitmaps because they map bits (representing colors) to specific grid locations.
Q.19 We translate a two-dimensional point by adding:
Translation distance
Translation difference
X and Y
Only (a)
Explanation
Translation is performed by adding translation distances (offsets) to the original coordinates of a point.
Q.20 Pixel can be arranged in a regular?
One dimensional grid
Two dimensional grid
Three dimensional grid
None of these
Explanation
Pixels on standard screens are arranged in a regular two-dimensional grid consisting of rows and columns.
