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.

The Raster scan system is a scanning technique in which the electrons sweep from top to bottom and from left to right. The intensity is turned on or off to light and unlight the pixel. The beam is swept back and forth from the left to the right across the screen. When the beam is moved from the left to the right, it is ON. The beam is OFF, when it is moved from the right to the left. When the beam reaches the bottom of the screen, it is made OFF and rapidly retraced back to the top left to start again. A display produced in this way is called raster scan display.
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.
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.

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.

Photoshop is a raster image editor. Raster and Bitmap are two words for the same thing, so Photoshop is raster or Bitmap image editor, somewhere you will see raster, somewhere bitmap as explanation but it is basically same thing. Photoshop is primarily designed to work with bitmap images which are raster images in other words.
