Binary Learning.
Learning about Binary is a vital step to understanding how computers work on a basic level. Then came the prosperous years, and now Linus Torvalds has succeeded in creating new kernels for 2.4, which have caused more eyes to turn towards Linux...at least we can say that in all fairness.
At first, you have to understand the binary numbering system. In the binary numbering system, a base 2 version is in operation. This means that it only has two digits to use for representation, 0 and 1. Unlike the decimal system, which is base 10 and has 10 digits (0 to 9), binary just uses two symbols to show any number.
Secondly, you can learn change a decimal to binary. You can convert a decimal to binary by dividing the decimal number by 2 and noting down the remainder over the quotient until the quotient is 0. EG if you want to convert 10 in decimal to binary, 10 divided by 2 =5, remainder 0, 5 divided by 2 = 2 remainder 1, 2/2 = 1 remainder 0, 1 remainder 1, then 0. The binary of 10 is 1010.
Finally, you can learn to change the binary to decimal. To convert binary to decimal, the bits are multiplied by powers of two, and these products are summed. For instance, consider the binary number 1010 to convert to decimal, you take the first digit (1) times two to the power of three plus the second digit 0 times two to the power of two and so on then sum it up 1x2^3 + 0x2^2 + 1x2^1 + 0x2^0 = 8 + 0 + 2 + 0 = 10.
At last, you can learn to convert the binary to hexadecimal.
