You can often hear phrases such as "binary file" or "binary clock." What do these different concepts have in common? Apparently, they are binary. What is binary?

The prefix bi- (Latin bi-) means binary. Binary is a sign of the subject, which says that the subject consists of two parts or two elements.

## What is a binary code

A binary code is a way of recording information using only two characters. Most often, these signs are 0 and 1. For example, if you write the digit 0 with a binary code, then it will be 000, 1 is 001. But if you write the remaining digits with the binary code that we used to perceive in the decimal number system, we get : 2 - as 010, 3 - as 011, 4 - as 100, and so on.

## What is a binary file

Binary (binary) files are called because their structural components - bytes - are a combination of 8 characters written in a binary code (8 bits). That is, one byte is eight zeros or ones in different combinations. Strictly speaking, all files are binary.They also speak about text files, but they are a kind of binary.

## What does binary option mean

A binary option is a tool for buying assets, in which the investor has only two possible options for the outcome of the transaction - either to obtain a fixed, previously known profit, or to lose all investments (all or nothing).

If you buy with the help of a binary option shares of any company, for example, for a period of 24 hours and the amount of \$ 1,000, and the shares during this time increase in price by 1%, then you can make a profit, say, 80%. And you will not have \$ 1,010, but \$ 1,800. But if the shares fall in price by the same 1%, you will not have \$ 990, but nothing will be left.

## Binary connections

Binary compounds are chemicals consisting of two chemical elements. Classic examples:

• water (H2O)consisting of molecules of hydrogen and oxygen;
• all oxides, including carbon dioxide (CO2);
• ammonia (NH3).

They also speak about binary alloys, that is, alloys consisting of two metals or metal and non-metal. So, bronze is a binary alloy of copper and tin, and cast iron and steel are binary alloys of iron with carbon.

There is still a binary clock.
