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.
one Megabyte
Uncompressed storage = number of pixels \(\times\) bits per pixel.
Pixels \(= 1024 \times 1024 = 2^{20}\).
Storage \(= 2^{20} \times 8\) bits \(= 2^{20}\) bytes \(= 1\) MB.
Check: each pixel takes exactly one byte, so the image needs as many bytes as it has pixels, \(2^{20}\) bytes.
Hence, one Megabyte.
