How hexadecimal helped me understand binary / 2
January 28, 2018
In my previous post I went about explaining how hexadecimal works. I suggest you read that post before reading this! I'm still getting to grips with the whole blogging experience and still deciding if this is the best way to explain computing ideas. I'm toying with the idea of creating some videos, but not yet sure how I'd create them/how well they'd go down.
With this post I just wanted to quickly add a part 2 to my first post regarding hexadecimal, more specifically, how it helped me to understand binary.
While learning about hexadecimal I came across the programming mode my computers calculator (currently running elementary OS, a Linux distro). I had seen this sort of calculator before but didn't have any idea what it was for (back in my 'Windows is awesome!' days :/ ). Now it has become extremely useful and really helped bridge the gap between hexadecimal, decimal and binary. You can type in a number in decimal and it will give it to you in hexadecimal, binary, and even octal (I'd never come across this before, but as you can probably guess it is base 8).
The picture is the aforementioned calculator and the drop down list gives you the options to convert what you've typed in into a different base. It also allows you to see how these numbers work in binary, with 64 digits of binary laid out for you, with the option of turning them on and off as you like (it says 63 in the calculator, remember in computer science you count from 0!) This has proved extremely useful for me and almost negates the need to get into the grit of understanding hexadecimal, however I still think it's really important to understand what you're using to prevent further issues down the line, so don't just use this as a cop out.
To round this rambling up, I'll just say this: being able to see side by side how hexadecimal and binary are converted from a decimal number was the one thing that helped me understand the different bases the most. Hopefully this will be able to give you a clearer understanding of different bases too!
