Given an image of size 1024 × 1024 pixels in which intensity of each pixel is an 8-bit quality. It requires _______ of storage space if the image is not compressed.
UGC NET - 2014,
Answer: B
The image needs one megabyte of storage.
There are \(1024 \times 1024 = 1{,}048{,}576\) pixels and each takes 8 bits, which is one byte, so the image takes \[ 1024 \times 1024 \text{ bytes} = 1 \text{ MB}. \]
One terabyte and 8 terabytes are far too large, and 8 megabytes would be correct only for 8 bytes per pixel. A byte-per-pixel image of 1024 by 1024 pixels is the standard example of one megabyte, because 1024 times 1024 is 2 to the power 20.
