## FAQs about Binary Code

A collection of the most Frequently Asked Questions about the Binary Code and the Binary Number System:

**📖 What is the definition of Binary Code?**

Binary Code can be defined as a way to **represent information** (i.e. text, computer instructions, images, or data in any other form) **using a system made of two symbols**, which are usually “0” and “1” from the binary number system.

**💡 Who invented the Binary code and when?**

The Binary Code was invented by **Gottfried Leibniz in 1689** and appears in his article *“Explanation of the binary arithmetic”.*

**✏️ How do you translate Binary to Text?**

In order to convert binary to text, you have two options: you can either **use an online translator** (like the one provided for free by ConvertBinary.com), or you can **do it manually**.

If you want to learn how to convert binary code to text manually, you can **read this guide**, or **watch the associated tutorial**.

**🤔 What is the purpose of converting between Text and Binary Code?**

There are many possible reasons for that: for example, you may want to send someone a message that is not immediately readable, or maybe a game that you are playing is challenging you with some binary code that you need to translate in order to move forward.

Also, you may find some random binary code on the internet, and then you want to know what it means.

Perhaps you need to practice binary conversion to get a better understanding of how computers use binary, or maybe you simply enjoy playing with nerdy stuff.

**🔎 Is Binary Code still used?**Absolutely! Computers use binary – the digits 0 and 1 – to store data. A binary digit, or bit , is the smallest unit of data in computing.**Computers use binary to represent everything** (e.g., instructions, numbers, text, images, videos, sound, color, etc.) they need to store or execute.

Even if you write your program source code in a high-level language like Java or C#, which compile down to an intermediate language (bytecode and CIL, respectively), the required runtime environment that interprets and/or just-in-time compiles the intermediate language is a **binary executable**, and the operating system it runs on also consists of binary instructions.

**🖥️ Why do computers only understand 0 and 1?**Because their hardware architecture was easier to work with in the early days of electronic computing using only **zeros and ones**.

Every modern computer has a Central Processing Unit (CPU) which performs all arithmetic calculations and also performs logical operations.

The CPU is made out of millions of tiny components called transistors, which are basically **switches**. When the switch is ON it represents 1, and when it is OFF it represents 0.

Therefore all computer programs must be **ultimately translated to binary code instructions** which a computer CPU can interpret and execute.

**⚙️ Why is binary code important?**Binary is important because of its implementation in modern computer hardware.

In the early days of computing, computers made use of analog components to store data and perform their calculations. But this wasn’t as accurate as binary code, because the analog method caused small errors that, compounding on each other, caused significant issues.**Binary numbers simplified the design of computers**, since the transistors based on binary logic (where inputs and outputs can only be On, or Off) turned out to be cheaper and more simple to build, and also much more reliable to operate.

**🎓 Is knowing binary useful?**

**For a computer scientist**, having an understanding of how computers store and manipulate information **is essential**.

If you do anything with hardware, boolean logic and binary become essentially intertwined and totally indispensable.

Most modern programming languages abstract the binary representation from the programmer, but the underlying code still gets translated to binary before it is sent to the machine for processing.

**⚡ Why is binary used?**

Modern computers use binary code to store and manipulate information, because their circuitry can easily read an On or Off charge, and transmit it very reliably too.

Furthermore, the logic of binary is easy to understand and can be used to build any type of logic gates.

**👀 Is binary code universal?**

There is no such thing as a “universal binary language”. Binary is a form of encoding information (i.e. characters) onto numbers, but that doesn’t change the contents of the information.

For this reason, if you encode a sentence written in English onto Binary, as you decode it back from binary to ASCII text it will still read in English, i.e. it won’t translate automatically to other languages.
