About Binary Number Systems

A binary number system is comprised of combinations of 0 and 1. This base-2 system is used internally by most modern computers or similar devices. A bit is the basic unit of information in computing where the bit is either a zero or a one.

The encoding of data in a bit can be traced back to early computing devices that used punch cards as well as in other 19th century contrivances such as the teletype machine. Communication systems like Morse code also use a binary base method to convey information.

It can be quite time consuming converting binary strings to numbers by using mental calculation. Instead, convert binary strings to regular numbers automatically by using this online converter.
