UGC NET Questions (Paper – 1)

Bitmap graphics represent images as grids of individual pixels, each with its own colour value. Common formats like JPEG and PNG use this approach and are widely used for photographs. Bitmap images may lose quality if scaled excessively. Thus, the type of graphic described is bitmap.

Option A:
Option A is correct because bitmap, or raster, graphics are defined by pixel arrays and match formats like JPEG and PNG.

Option B:
Option B, vector, graphics are composed of mathematical paths and shapes and scale without loss of quality, which differs from pixel based images.

Option C:
Option C, 3D, graphics involve three dimensional models and rendering, not simple two dimensional pixel arrays.

Option D:
Option D, holographic, imagery refers to three dimensional representations created through interference patterns and is not the basic format for digital photos.
