Learn How to Convert Binary Numbers: From Binary to Denary and Beyond!

Converting numbers between different number systems is a fundamental concept in computer science and mathematics.

Binary to denary conversion involves translating numbers from base-2 (binary) to base-10 (decimal/denary). This process can be done manually using a binary table or through digital tools like a binary to decimal converter online. When converting manually, each binary digit (0 or 1) is multiplied by its corresponding power of 2, starting from the rightmost digit. For example, in binary to decimal conversion examples like "1011 binary to decimal", we calculate: (1×2³) + (0×2²) + (1×2¹) + (1×2⁰) = 8 + 0 + 2 + 1 = 11.

Binary shifting operations are essential in computer programming and digital electronics. A binary shift moves all digits in a binary number left or right by a specified number of positions. Binary shift multiplication occurs when shifting left (equivalent to multiplying by powers of 2), while binary shift division happens when shifting right (dividing by powers of 2). For instance, when you perform a binary shift of 3 places right on the binary number 10001110, the result demonstrates how binary shifting can efficiently perform mathematical operations. These concepts are often taught alongside truth tables, which show all possible combinations of inputs and outputs in logical operations. Students can practice these concepts through binary shift questions and explore resources like BBC Bitesize for additional learning materials. Understanding binary patterns and their manipulation is crucial for computer programming, particularly when working with Python or other programming languages that handle binary data.

Converting between different number systems, including how to convert binary to hexadecimal and how to convert denary to hexadecimal, builds upon these fundamental concepts. Common examples like 111 binary to decimal and 1010 binary to decimal help students grasp these conversion principles through practice. These skills are essential for anyone studying computer science, digital electronics, or programming, as they form the foundation for understanding how computers process and store information at the most basic level.

Binary to Denary Conversion Understanding how to convert between binary and denary decimaldecimal numbers is crucial for computer science. When converting binary to denary, each digit is multiplied by its corresponding power of 2 and then summed together. For example, the binary number 1011 converts to decimal by calculating 1×81×8 + 0×40×4 + 1×21×2 + 1×11×1 = 11.

Example: Converting binary 1010 to decimal: 1×8 + 0×4 + 1×2 + 0×1 = 8 + 0 + 2 + 0 = 10

Hexadecimal Conversions How to convert binary to hexadecimal involves grouping binary digits into sets of four nibblesnibbles and converting each group to its hex equivalent. For instance, binary 00011110 splits into 0001 11 and 1110 EE, giving hexadecimal 1E. A binary to hexadecimal conversion table is essential for quick reference.

Definition: A nibble is a group of 4 binary digits, representing half a byte.

Character Encoding Computers use character sets to represent text as binary numbers. ASCII AmericanStandardCodeforInformationInterchangeAmerican Standard Code for Information Interchange uses 7 bits to represent 128 different characters, while Unicode expands this to multiple bytes to accommodate international character sets.

Vocabulary: Character sets are standardized collections of characters with their corresponding binary representations.

Digital Image Representation Images are stored as collections of pixels, with each pixel's color represented in binary. The image quality depends on two key factors:

  • Color depth: determines the number of possible colors 2nwherenisthebitdepth2^n where n is the bit depth
  • Resolution: total number of pixels width×heightwidth × height

Highlight: File size inbitsin bits = resolution × color depth

Sound Digitization Digital sound recording involves converting analog sound waves into binary data through sampling. The quality and file size depend on:

  • Sample rate measuredinHzmeasured in Hz
  • Bit depth numberofbitspersamplenumber of bits per sample
  • Duration of the recording

Example: A 44.1 kHz sample rate with 16-bit depth for 1 minute would result in: File size = 44,100 × 16 × 60 = 42,336,000 bits

This comprehensive understanding of binary systems and digital data representation is fundamental for anyone studying computer science or working with digital systems.

Binary Number Systems and Conversions

Binary is the base-2 number system used by computers, consisting of only 0s and 1s. This section covers the fundamentals of binary numbers and how to convert between binary and denary base10base-10 systems.

Definition: Binary is a base-2 number system used by computers, representing the flow of electricity with only two digits 0and10 and 1.

In binary, each digit represents a power of 2, increasing from right to left. Most commonly, 8-bit binary numbers are used, representing denary numbers from 0 to 255.

Example: An 8-bit binary number table:

2^72^62^52^42^32^22^12^0
1286432168421

To convert binary to denary, add up the place values where there is a 1 in the binary number. For instance, 10101010 in binary equals 170 in denary 128+32+8+2128 + 32 + 8 + 2.

Highlight: The leftmost bit in an 8-bit binary number is the most significant bit, with a value of 128.

Converting from denary to binary involves subtracting the largest possible place value and placing a 1 in that position, repeating until reaching 0. Alternatively, you can divide the denary number by 2 repeatedly, noting the remainders.

Example: Converting 42 to binary: 42 - 32 = 10, 10 - 8 = 2, 2 - 2 = 0. This gives us 00101010 in 8-bit binary.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!
