Conversion of Keyboard Characters to Binary and Hexadecimal (Part 3 of 5)

[0:03]So to answer why we have eight here. We simply make use of the weight values here. Eight obviously because we simply get binary ones with weight value which is eight, and it is here. The rest should be zero. So simply eight plus Nothing, nothing and nothing it's eight. What about if we would like to have the value 10? What will be the value or binary digit equivalent here? So, we simply think or combine binary digits to have a sum of 10. So, basing the weight values, we simply pick 8 and 2 for us to have 10. So, the binary equivalent of 10 is simply 1 0 1 and 0 because 8 + 2 is 10. What about 12? For us to have a binary equivalent of 12, we simply pick binary or weight values to have a total of 12. So, we simply pick 8 and 4 because that's obviously obviously 12, and the rest are not useful. So, 12 binary equivalent is 1 1 0 and 0 because 8 and 4 is simply 12. What about here? So obviously, the binary digit equivalent of 4 is this 0 1 0 0 because of the weight value here. And if you'd like to have a binary equivalent of the value 15, you simply think of binary digit combinations to have a total of 15. So, it's 8 + 4 is 12, + 2 is 14, + 1 is 15. Therefore, the value 15 will have its binary equivalent of 1 1 1 and 1.
