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.

It uses the Binary Numbering System.

Computers store and process data in binary form: current on or off, location magnetised or not, laser reader hits a pit or not.

Nearly all computer math is based on variants of binary numbering. Printouts of computer memory data will combine the binary numbers into four bit groups called hexadecimal digits.

Most computers use ASCII (or some similar) encoding, in which 'A' is represented as 65, or 01000001 binary. Older IBM mainframes use an entirely different encoding.

the importance of binary numbers in standard computing is basically everything. computers only understand base 2, that is a 0 (off) and a 1 (on). every piece of data passed through any part of the computer is done so using base 2 (binary). that said, there are theorised base 3 computers, called 'genetic computers' which use genes and magnetism to produce a base 3 process, but this was only done as a computer sciences project and is likely to not every be implemented in the mainstream.

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))
