There are just two binary digits, which are 0 and 1. "Binary digits" is often shortened down to "Bits". Putting binary digits together you can make up the codes that are used to store various characters from your keyboard.
For example the binary code for "A" is 01000001. In decimal that would be 65. For "a" the binary code 01100001, which is 97 in decimal. The letters, digits, punctuation symbols and other characters on your keyboard, as well as ones that don't appear on your keyboard, but would in other countries, all have binary codes. This is the way they are stored in your computer. It is possible to get some of these other characters by using the decimal equivalent of binary codes.
If you are using a PC, open up Notepad, which you should get through Programs and Accessories from your Start menu. On the right side of your keyboard is the numeric keypad. Make sure the num Lock light is on. Press and hold down the Alt key, which is on the left of your space bar. Keeping it held down, on the numeric keypad, not the numbers across the top of your keyboard, type 65 and then let go of Alt. You should get an A. Try it again with 97 and you will get a. Try any number between 0 and 255 and you will get various characters, including ones that are not on your own keyboard. These will include letters from other alphabets like é (130) or â (131), or symbols like the one used for temperature ° (248) and many others. apex.. chaos
Gray code is where only one bit changes at a time. Binary code is where one or more bits change at a time. An example, for three bits, with binary on the left and gray on the right, with the changing bits underlined...

The advantage of binary code is that it is easy to convert to a numeric value. The advantage of gray code is that it makes very stable position digitizers, because only one bit changes at a time, resulting in uncertainty of only one bit.

The grain structure of gray cast iron falls into 4 main classifications, or types. The most desirable of the four is called Type 'A' wherein the carbon is solidified into flake like crystals, in a random distribution. The size is also classified, in sizes ranging from Size 2 to 7. The best grain structure for general service castings is Type 'A', Size 3 to 5. The smaller the size number indicates the longest flake length, and the excessively long flakes in Size 2 will render the iron somewhat weaker, so the most desirable size is a mixture of 3, 4 and 5. Some applications may call for Type 4, but generally the other Types are undesirable and are the result of defective chemistry or a process defect.
OK. I have it. What now ?
The Gray Code is a type of binary code developed by a programmer named Frank Gray. Gray code is a binary numeral system that differ than normal binary code, and is used widely to detect errors in software.
The reflected binary code, also known as Gray codeafter Frank Gray, is a binary numeral system where two successive values differ in only one bit.Here is an example of a 4-bit Gray code:0000000100110010011001110101010011001101111111101010101110011000
gray code is one which changes one bit at a time but binary code is one which changes one or more bit at a time. for example three bit binary and gray code the left one is binary and the right one is gray code.binary gray000 000001 001010 011011 010100 110101 111110 101111 100000 000
Gray Code is Reflective Binary code. One of the main disadvantages of Gray code is that it is very difficult to come up with an arithmetic logic unit to support Gray code.

I do not believe that is a valid binary number. All binary numbers must be divisible by 8
Converting Gray Code to Binary1). Write down the number in gray code.2). The most significant bit of the binary number is the most significant bitof the gray code.3). Add (using modulo 2) the next significant bit of the binary number to thenext significant bit of the gray coded number to obtain the next binary bit.4). Repeat step 3 till all bits of the gray coded number have been added inmodulo 2. The resultant number is the binary equivalent of the gray number.Converting Binary to Gray Code1).

assalam o alikum,i am hameed ullah and a student of electronic engineering. my question is that ,,,,,,,,,,, "why we converted a binary number into gray code" and what is the difference in odd parity and even parity
When going from one number to the next in Gray Code 1 bit only ever changes, whereas with binary more than 1 bit could change.
