It is simpler to code each digit as off-or-on (binary) rather than at 10 different voltages to represent the digits 0, 1, 2, ..., 9 if using decimal. There is a greater risk of errors in reading or writing information in the latter case.

Similarly, with optical data, it is safer to have a "pit" or "not-a-pit" which a laser can easily work with rather than pits of ten different depths.

### Why computer use number system?

Computers cannot understand languages. They can only compute data. Because of that, we use binary code because that is pure data.

Computers store data in binary digits - ones and zeroes. It is mainly here that hexadecimal is used, as a shortcut for binary; each hexadecimal digit corresponds to four binary digits.

### What is a difference between binary tree and binary?

I think a binary tree is a thing to help you search whereas binary is 100100101010, that thing that computers use...I think the difference is that a binary tree helps you search but binary is the thing that computers use:10010101001010 The term binary refers to the idea that there are "2" options. In terms of computers at a low level, this refers to 1's and 0's (high voltage and low voltage). A binary tree is a completely different concept. It is a type of data structure with a parent node that branches down into 2 child nodes at each level. If implemented as a binary *search* tree it is pretty efficient at searching data sets that are ordered (O(log n))
