Question

What is the atomic symbol equivalent of an image?

(a) Small group of blocks

(b) Small group of phoneme

(c) Small group of pixels

(d) Small group of points

This question was posed to me at a job interview.

Question is taken from Architecture in chapter Cognitive Radio Architecture of Cognitive Radio

Answer 1

The correct answer is:

(c) Small group of pixels

In the context of image processing and cognitive radio architecture, an "atomic symbol" often refers to the most fundamental unit or element used to represent information. For images, the basic unit of representation is a pixel. A group of pixels forms an image, and these pixels are the smallest building blocks that make up an image in digital form.

• (a) Small group of blocks: This is too vague and doesn't specifically relate to how images are represented.

• (b) Small group of phonemes: Phonemes refer to the smallest units of sound in language, not relevant to images.

• (d) Small group of points: While "points" can sometimes be used in image contexts (e.g., coordinate systems), pixels are more specifically the atomic units of digital images.

Therefore, (c) Small group of pixels is the correct answer.
