Binary Code Explained
Decoding the Language of Computers
Introduction to Binary and Binary Code
Have you ever wondered how computers understand and process information? How do they convert the images, videos, and text that we input into the machine language they require to run? The answer lies in the binary code. Binary is a base-2 numbering system that uses only two digits: 0 and 1. This language is the foundation of all computer technology, and without it, our world would be very different.
Binary code is a sequence of 0s and 1s used to represent data in a computer. It is the language that computers use to communicate with each other and with us. Each digit in binary code is known as a bit, which is short for binary digit. A bit can have one of two values: 0 or 1. These values represent the presence or absence of an electrical signal in a computer’s circuitry.
Binary Number System Explained
The binary number system is a system used to represent numbers using only two digits: 0 and 1. All digital electronics, including computers, use this system. In the binary system, each digit represents a power of 2. The rightmost digit represents 2^0, the next digit represents 2^1, the next digit represents 2^2, and so on. Each digit can either be a 0 or a 1.
For example, the binary number 1011 represents 1 x 2^3 + 0 x 2^2 + 1 x 2^1 + 1 x 2^0, which is equal to 11 in the decimal system. The binary number system is essential in computing because it allows computers to store and manipulate data using only two states, on and off.
How to Count in Binary
Counting in binary is straightforward. Start with 0 and keep adding 1 until you reach the maximum number that can be represented with the available digits. For example, if you have two digits, you can represent the numbers 0 to 3. The binary numbers for these digits are 00, 01, 10, and 11.
To count in binary, start with 0 and add 1. The next number will be 1. Add 1 again, and the number becomes 10. 1 again, and the number becomes 11. Another 1 again, and the number becomes 100. This pattern continues. Remember that each digit can only be 0 or 1.
Converting Binary to Decimal
Converting binary to decimal is also straightforward. Start with the rightmost digit and multiply it by 2^0. Move to the next digit and multiply it by 2^1. Keep moving to the left and multiplying each digit by the appropriate power of 2. Add all the results together to get the decimal equivalent.
For example, the binary number 1010 is equal to 1 x 2^3 + 0 x 2^2 + 1 x 2^1 + 0 x 2^0, which is equal to 10 in the decimal system.
Converting Decimal to Binary
Converting decimal to binary is a bit more complicated. The easiest method is to use the repeated division by 2 method. Start with the decimal number you want to convert and divide it by 2. The remainder will be either 0 or 1. Write down the remainder, and then repeat the process with the quotient. Continue this process until you reach 0. The binary number is the sequence of remainders written in reverse order.
For example, to convert the decimal number 10 to binary, you would divide 10 by 2, which gives a quotient of 5 and a remainder of 0. Write down the remainder, which is 0. Divide 5 by 2, which gives a quotient of 2 and a remainder of 1. Write down the remainder, which is 1. Divide 2 by 2, which gives a quotient of 1 and a remainder of 0. Write down the remainder, which is 0. Divide 1 by 2, which gives a quotient of 0 and a remainder of 1. Write down the remainder, which is 1. The binary number is 1010.
Translating Binary into Text using ASCII
ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard used to represent text in computers. Each character is assigned a unique 7-bit binary code. ASCII is used to translate binary into text.
To translate binary into text using ASCII, divide the binary number into 7-bit chunks. Convert each chunk into its decimal equivalent and look up the corresponding ASCII character in a table.
For example, the binary number 01000001 01000010 01000011 represents the characters A, B, and C in ASCII. The first 7 bits, 0100001, represent the decimal number 65, which corresponds to the character A. The next 7 bits, 01000010, represent the decimal number 66, which corresponds to the character B. The last 7 bits, 01000011, represent the decimal number 67, which corresponds to the character C.
ASCII Code and its Role in Binary to Text Conversion
ASCII code is essential in binary to text conversion because it assigns a unique binary code to each character. This allows computers to manipulate text in a standardized way. ASCII code was originally designed for use with English characters, but it has been extended to include characters from other languages, symbols, and control codes.
Many applications use ASCII code; for example, email, text messaging, and document encoding. Understanding ASCII code is essential for anyone who works with text in a digital environment.
Examples of Binary to Text Conversion
Here are some examples of binary to text conversion using ASCII code:
- 01001000 01100101 01101100 01101100 01101111 – Hello
- 01010100 01101000 01100101 00100000 01100011 01100001 01110100 – The cat
- 01110011 01100001 01110100 00100000 01101001 01101110 00100000 01110100 01101000 01100101 00100000 01101000 01100001 01110100 – sat in the hat
What are Bits and Bytes?
The smallest unit of measurement in binary code is a bit. A byte, on the other hand, is a group of eight bits. Bytes represent larger amounts of information, such as numbers, letters, and symbols. In computer memory and storage, data is measured in bytes, with the smallest unit being a byte.
One byte can represent up to 256 different values, which is enough to represent all the letters and numbers in the English language, as well as other characters like punctuation marks and symbols. For example, the letter ‘A’ in binary code is 01000001, while the number ‘5’ is 00110101.
How Binary is Used in Computer Systems
Every computer system is made up of a combination of hardware and software. Binary code plays a crucial role in both. In hardware, binary code is used to represent the electrical signals that run through the circuits of a computer’s Central Processing Unit (CPU). The CPU is the brain of the computer, and it processes all the information that is fed into it.
In software, binary code represents the instructions that a computer needs to run a particular program. These instructions (machine code) are executed by the CPU. Every program that you use on your computer, from a simple text editor to a complex video game, is made up of binary code that the CPU can understand and execute.
How Binary is Used in Memory and Storage
Binary code is necessary to store and retrieve data in computer memory and storage. In memory, data is stored in binary code as electrical charges. When a computer needs to access data, it retrieves the binary code from memory and converts it back into the original data format, such as text or an image.
In storage, data is stored in binary code as magnetic charges on a hard drive or as electrical charges on a solid-state drive. When a computer needs to access data from storage, it retrieves the binary code and converts it back into the original data format.
Examples of Binary Code in Everyday Life
Binary code is everywhere around us, even if we don’t realize it. Every time we use a computer, watch a video, or even make a phone call, we are interacting with binary code. For example, when you watch a video on YouTube, the platform sends data to your computer in binary code and then your computer converts this binary code into the video that you see on your screen.
When you make a phone call, your voice is converted into binary code and transmitted over the phone network. The recipient’s phone then converts the binary code back into your voice. Even when you use a simple calculator, the numbers you enter are converted into binary code before they are processed by the calculator.
Binary Operations and Logic Gates
Binary operations and logic gates include addition, subtraction, multiplication, and division are used to manipulate binary code in computer systems. Calculated using binary code, these operations make complex calculations in computer programs.
Logic gates, on the other hand, are used to perform logical operations on binary code. These gates include AND, OR, and NOT gates. They are used to make decisions based on the binary code that is input into them. For example, an AND gate will output a 1 if both of its inputs are 1, and a NOT gate will output the opposite of its input.
