What is a raster device?
Common examples of raster devices are computer monitors (e.g. cathode ray tube, LCD). The term "raster device" means a device that is composed of discrete image samples or pixels.
Advantages of raster scan?
Raster-scan:-q1) Raster displays have less resolution.q2) The lines producced are ziz-zag as the plotted values are discrete.q3) High degree realism is achived in picture with the aid of advanced shading and hidden surface technique.q4) Decreasing memory costs have made raster systems popular.Random scan:-q1) Random displays have high resolutions since the picture definition is stored as a set of line drawing commands and not as a set of intensity values.q2) Smooth lines are produced as the electron beam directly follows the line path.q3) Realism is difficult to achieve.q4) Random-scan system's are generally costlier.
Where the variables are stored in the computer?
Variable stored in the memory block inside the RAM. whenever we declare a variable it would take space in main memory and consume it's size from RAM.
How does a Backup tape work?
A backup tape works by copying information from a computer and storing it. If something happens to a computer or a hard drive, a backup tape still has the information that was also stored on the hard drive of a computer.
Is raster scan displays same as bit-mapped displays?
raster scan display -based on television technology.where as random scan display based on hard copy devices.raster scan display cannot directly pass electron beam through the scan line..but random scan directed the beam toward the scan line.
What is a raster scan system What is a picture element how it is?
Raster scan, or raster scanning: is the pattern of image detection and reconstruction in television, and is the pattern of image storage and transmission used in most computer image systems. The word raster comes from the Latin word for a rake, as the pattern left by a rake resembles the parallel lines of a scanning raster. Picture element: In a raster scan, an image is cut up into successive samples called pixels, or picture elements, along scan lines. Each scan line can be transmitted as it is read from the detector, as in television systems, or can be stored as a row of pixel values in an array in a computer system. On a television receiver or computer monitor, the scan line is turned back to a line across an image, in the same order. After each scan line, the position of the scan line is advanced, typically downward across the image in a process known as vertical scanning, and a next scan line is detected, transmitted, stored, retrieved, or displayed. This ordering of pixels by rows is known as raster order, or raster scan order.

What is shaded computer animation called?
Shaded computer animation images are known as raster graphics.
Give two main types of computer graphics?
raster and vector
How are picture stores in calligraphic and raster refresh display devices?
computer graphics
What is raster printing?
Raster printing refers to the method of printing which uses the raster image processor. The raster printing usually produces a raster image called a bitmap.
Difference between Vector graphics and roster graphics?
Raster graphics are stored as pixels, vector graphics are stored as geometric primitives. Images of the latter type can, in principle, be scaled infinitely, and pixelization will not occur.
Vector is the earliest or raster is the earliest?
Raster.
Is Photoshop a raster or vector based program?
raster
What are the best computer drawing programs available?
Photoshop for raster images. Illustrator for vector images. These are the industry standards.
When was Hermann Raster born?
Hermann Raster was born in 1827.
