What is the interactive computer system?
interactive computer system involves a two-way communication between computer and user.
here the observer is given some control over the image by providing him with an input device for example the video game controller of the ping pong game.
this helps him to signal his request to the computer. The computer on receiving signals from the input device can modify the displayed picture appropriately.
the picture changes according to the users command.
What is resolution?
The maximum number of points (pixels) that can be displayed without overlap on a CRT is referred to as their solution. It is also defined as maximum number of points displayed horizontally and vertically without overlapping on a display screen.
More precise definition of resolution is no of dots per inch(dpi/pixel per inch) that can be plotted horizontally and vertically. Resolution of 1280*720 means that there are 1280 horizontal lines and 720 vertical lines or 1280 pixels horizontally and 720 pixels vertically. We can say that the higher is the pixel resolution, the higher is the quality of the image. there are two types of resolutions.
1. Image resolution
Image resolution is defined as the distance from one pixel to the next pixel i.e., pixel spacing.
2. Screen resolution
screen resolution is defined as the number of pixels in the horizontal and vertical dirrection.
What is the impact of resolution on display devices?
