All modern computers **| kəm.ˈpjuː.təz** | and computer-based devices, such as smartphones, cameras, etc. use the binary system.

The binary system **| ˈbaɪ.nə.ri ˈsɪ.stəm | **uses only two figures **| ˈfɪ.****ɡ****əz |** or symbols: **| ˈsɪm.bl̩z |** 0 (zero) and 1 (one). It is very important in computers.

Each digit **| ˈdɪ.dʒɪt** **|** is called bit **| bɪt** **|**. So, with 2 bits we can express 4 different numbers: 00, 01, 10 and 11. In general, with n bits, we can express 2^{n} numbers.
