# Digital signal binary numbers and computer use

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 computers. 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 to 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 a 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. 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 online , computers 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 digits 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 bitâ€”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 switches 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 other 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. Converting text to Binary is a two step process.

First you need to convert each letter or All computer language is based in binary code.
