What is a binary coding system?
A typical answer is as follows: It represents data using only two digits: 0 and 1. Each digit in binary code is called a bit. These bits combine to form larger units of data, allowing computers to process information. However, there is no doubt that a CD (Compact Disc) contains data written using a binary coding system. The data on a CD is stored as microscopic pits (depressions) and lands (flat areas) on the reflective layer. Hence, we cannot recognize only two digits: 0 and 1 on the CD surface.
Again, what is a binary coding system?

@Mohammad Tahir Ansari; from the dictionary: combine == join or merge to form a single unit or substance - I am pretty sure that the answer must be different. Still, I am looking for a relationship between 0/1 and pits (depressions)/lands (flat areas) in the context of the CD content meaning. 0/1 we can use on the paper, for example, but cannot be used on the CD surface. They cannot be also used in memory, in processors, etc.

A binary coding system is a method of representing data using only two symbols or digits: 0 and 1.
These symbols (called bits) combine to represent all kinds of data in computers. For example, text, images, and sounds are all converted into long strings of 0s and 1s for storage and processing.
