# Why computers use binary and hexadecimal numbers to store data

We all know what decimal numbers are: However, many other numeral systems exist and you might have heard about or seen others, like hexadecimal numbers for example: These hexadecimal or binary numbers can easily be converted to the well-known decimal numbers. Other numeral systems exist because there are specific uses where a certain numeral system is easier to use and offers advantages over another. Binary and hexadecimal numbers are widely used in computer science.

Binary numbers can be considered the very basic representation of a number in an electronic device. This will help to explain why binary numbers are so important. The very first computers used binary numbers, and they are still used today.

Every computer is made up of many electronic components. That is why a basic knowledge of electronics is needed to understand how and why binary numbers are used in **why computers use binary and hexadecimal numbers to store data.** A computer is built with many connections and components, which are used to transfer and store data, as well as communicate with other components. Most of that storing, transferring, and communicating happens with digital electronics. In electronics, a voltage level or current flow is a way to represent a value.

For example, 5V volts or 0. The makers of electronic devices could, of course, assign any meaning that they want why computers use binary and hexadecimal numbers to store data different voltage values. You would end up with 0. This means that when building an electronic device, it is most often desired to have the energy consumption as low as possible and to have why computers use binary and hexadecimal numbers to store data low voltage.

Furthermore, electronic signals are not always very steady and can vary because of surrounding influences, like nearby internal circuits for other electronic devices. This might then lead to voltage levels where it gets difficult to distinguish which value it represents. As a result, we cannot divide the 5V into 10 steps. The values could be misinterpreted. A computer might suddenly make wrong calculations because of random interference.

This example of voltage ranges shows that it is necessary to have a safe range between two voltage levels in order to read the correct value with percent probability. There are additional methods on the software level to verify that data is read correctly, but this is out of the scope of this article.

Binary comes from the Latin language and means that something is composed of two things. Binary electronics are usually called digital electronics. Another major reason is because a lot more circuitry is needed to distinguish between more than two voltage levels.

Each additional state needs about the same amount of additional circuitry. Quantum computing, however, might one day replace the binary system. It might be the next big step in how our computers work! What does a Binary Number Mean?

Strings of 0s and 1s, Binary numbers are often used to operate computers. But why is that? Why do computers convert to and from binary and **why computers use binary and hexadecimal numbers to store data** just use base 10?

Here we are going to provide you with all the answers so that you know exactly why computers use binary numbers! Modern day computers use binary numbers to operate—this is a fact well-known to people studying computer science or to those using these machines on a more than frequent basis.

When bit is uttered, the person using it is trying to define the binary digit contraction—an item that can only hold a 0 or 1. The bits are organized into eight groups and these groups are referred to as octets or bytes. Often measuring 23 or 64 bits, the octets can be organized into words. And, this is something most people know about. Why are binary numbers used by computers? The good news is that the reasons why engineers and scientists use the binary number system for computers are easily understandable.

After all, you can easily take text today and convert into binary online. Used by computers and some other electronic devices, the binary system is based on two symbols: This indicates the turning on or off an electrical signal or a base 2 exponent. This is probably a bit confusing for you, but the good news is that this concept is explained in detail here. We finally come to the million-dollar question: Nevertheless, we will try our best to come up with answers that sound logical and support the use of binary numbers by computers.

To present numerical data in our daily life, we use the decimal number systems. Instead, computers represent numbers by using the lowest base number system used by us, which is why computers use binary and hexadecimal numbers to store data. This is the binary number system. Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system.

For this reason, binary is measured as a two-state system i. Also, to keep calculations simple and convert into binary onlinecomputers use the binary number system. But, thanks to the binary system, only four rules are required by the computers for calculations. Last but not the least, a major reason computers use the binary system is that the two-state system is the number system best suited to the optical and magnetic storage components of the computer.

If you take only a quick glance at both, you will immediately assume that the binary system takes up more space than the decimal system. The reason many people assume that the binary system takes more space than the decimal system is because of the way the former is written on the computer screen.

You can always decrease the number of why computers use binary and hexadecimal numbers to store data used for representing a number by increasing the base, but it is simply impossible to create a digital circuit that uses anything other than two as base to operate. So, ready to convert into binary online?

With the help of switches, you can encode numbers into binary format. This system could be used by several digital devices including watch, digital TV decoder box, calculator, burglar alarm, cell phone and a computer.

In the memory, values are stored in binary format. Suppose a bank of eight rocker switches were available to you and depending on whether it is on or off, each switch could represent 0 or 1.

Someone else would be able to read the number if they looked at the switches. Transistors are used in computers to implement switches. It is the single bit—something we touched upon earlier. Only a single switch is required to implement this configuration memory.

You get a byte when eight switches are combined together. Convert into binary online to get a better understanding of this. The why computers use binary and hexadecimal numbers to store data can be set on and off by the digital hardware. Did you get the answer to your question i. So, why do computers not use this system and use binary instead? The answer to this is pretty straightforward.

This means that just two numbers: On the why computers use binary and hexadecimal numbers to store data hand, if the computers used the decimal system, there would be ten possible states to a switch. This is time consuming and completely unnecessary. So, to avoid the hassle and make things such as calculations simpler, computers use the binary number system. Now, do you understand why computers use binary numbers instead of decimal numbers?

Now that you know why computers use binary numbers, it is time for you to start converting text into binary. To avoid the hassle of using a physical tool, convert into binary online.

All the characters are stored by computers as binary data numbers. The assigned strings have the ability to correspond with symbols, letters, or instructions. Encoding data is what these codes are used for in computing. With an online binary conversion tool, you can convert to and from binary.

You can also convert the base system typically used by us with this tool. Additionally, in case you require four binary digits to represent a single hex digit, you can use this tool to convert to and from binary and hexadecimal.
